Parallel Arrays - User Input Integer 1-12 / Output Name Of Month And Number Of Days In That Month
May 11, 2015
I've been working on a question using parallel arrays where the user inputs an integer 1-12 and the output will be the name of the month and the number of days in that month. This is what I have so far
import java.util.*;
public class DaysMonth
{
public static void main (String args[]) {
Scanner keyIn = new Scanner(System.in);
int[] days = new int[]{31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};
I have written program for rainfall that will store and give total, average, least and most. The program stores the input of rainfall for each month. However at the end it suppose to print out the month with the least and most rainfall. I am getting this on the print for
The month with the most rainfall: [Ljava.lang.String;@79a7bd3b
and for
The month with the least rainfall: [D@7378aae2[Ljava.lang.String;@79a7bd3b
Write a program that prompts the user to input an integer and then outputs both the individual digits of the number and the sum of the digits.
Now I have a code for spacing out the integers, and I have a separate code for adding the digits. But I am not sure how to merge them together. Both of them work independently
Spacing code: import java.util.*; public class SumoftheIntegers { static Scanner console=new Scanner(System.in); public static void main(String []args) { int num1, test, rem; int counter = 0;
[Code]...
Now the sum of the integers code:
import java.util.Scanner; public class sum { public static void main(String[] args) { // Create a Scanner Scanner input = new Scanner(System.in); // Enter amount System.out.print("Enter an integer: "); int integer = input.nextInt();
I want to be able to use the current date to solve a math problem, specifically as follows:If today is March 17, the math problem of the day should be:
(Month times Day of Month) + 99 = Answer of the Day
(3 x 17) + 99 = 150
How can I create a java script to find the current month and the current day of month, multiple those two together, then add 99 and display the answer as a result.
I have an assignment where I'm supposed to write a program where the user inputs a month between 1-12 and then the right amount number in every month. I've tweaked the code a bunch of times, but I keep getting this error message:
insert "}" to complete StatementKALENDER_3.java insert "}" to complete BlockKALENDER_3.java
The code:
import java.util.*; import java.util.Scanner; public class KALENDER_3 } public static void main(String[] args){ Scanner scanner = new Scanner (System.in); System.out.print("Skriv ett manadsnummer: ");
[code].....
I think I have just forgot to put in a few { } symbols, maybe an open loop?
I am assigned with a project that will as the user for the amount of days they would like data entered, then loop asking them for these numbers. once it reaches the entered amount of days it will display a menu for which the user can enter the number they want on the list and it will display the data. the menu has 6 items. Total, Average, Determine if its a Drought, Flood or normal rainfall, highest of data entered, lowest of data entered, and 6 is to quit the program.
So far i have total and average working properly. Still looking at how to display drought, flood, and normal.
Main problems, i cannot get highest and lowest to display correct data.
Also when entering 6, or an invalid menu choice, neither "goodbye" or "invalid choice, choose again" gets printed. Rather the loop for entering data continues.
import java.util.Scanner; public class RainAnalysis { /* * Project 1 This program will analyze the rainfall for the number of days a user inputs. */
public static void main(String[] args) { Scanner keyboard = new Scanner(System.in); int numOfDays = 0; double rainfallAmount = 0.0;
[Code] ....
Here is a sample output to show what happens when i put in 6 after the menu is displayed.
also i noticed that it does not say the correct day when displaying the lowest and highest rainfall. this is because i put count, i did not know what else to put in order to get the correct day.
how many days do you want to monitor rainfall?5
Enter the rainfall for day 1.01 Enter the rainfall for day 2.1 Enter the rainfall for day 36 Enter the rainfall for day 43 Enter the rainfall for day 51
Rainfall Data Display Menu: 1 - Display total rainfall. 2 - Display rain average for the period. 3 - Display if drought, flood, or normal conditions. 4 - Display the day and amount of the highest rainfall. 5 - Display the day and amount of the lowest rainfall. 6 - Quit the program.
Enter your choice: 4 Day5 has the highest rainfall with 6.0 inches.
Rainfall Data Display Menu: 1 - Display total rainfall. 2 - Display rain average for the period. 3 - Display if drought, flood, or normal conditions. 4 - Display the day and amount of the highest rainfall. 5 - Display the day and amount of the lowest rainfall. 6 - Quit the program.
Enter your choice: 5 Day5 has the lowest rainfall with 0.1 inches.
Rainfall Data Display Menu: 1 - Display total rainfall. 2 - Display rain average for the period. 3 - Display if drought, flood, or normal conditions. 4 - Display the day and amount of the highest rainfall. 5 - Display the day and amount of the lowest rainfall. 6 - Quit the program.
I'm building a text based "game" where you are communicating with this android creature called Gargoid , at a VERY primitive level . how it works is, simply the user type in a sentence which is decoded for meaning by comparing it with a built in list of words in order to figure out what the user is saying, and then reply with a a relevant response also from a list of built in words. the whole thing would look something like this,
user: what is your name Gargoid : my name is Gargoid, nice to meet you user: how is the weather Gargoid: the weather is wonderful
so far I have 11 arrays which are the following
String[] for user typed in words used for comparison to find meaning ..An Array of String[] , 7 so far, to hold what I call the Gargoid dictionary for example String[] greeting={hi,hello,aloha}, words that indicates greeting int[] called frequency to determine which of the 7 arrays have the greatest "relevancy" to what is being said. and finally another String[] for responses here's the actual code, I want you guys to tell me if there's a way to reduce all this never ending number of arrays? and also is this code a good application of object oriented programming?
MainClass public class GargoidMain { public static void main(String[] args) { TheKeyBoard keyboard=new TheKeyBoard(); TheTranslator translator=new TheTranslator(); TheBrain brain=new TheBrain(); translator.translate(keyboard.userSaysWhat()); brain.respond(translator.userSays());
Using JOptionPane,ask for 10 numbers from the user.Use an array to store the values of these 10 numbers.Output on the screen the number with the greatest value.
I am trying to use parallel arrays to store names and job titles, then display the name/job title combo depending on which is entered. I have always struggled with arrays, so I'm sure that's where my issue is, but I am not sure how to resolve this one. I tried to use the toString() method with the jobs to see if that would allow the job title to match to one of the titles listed, and I tried to not use the toString() method with the names to see if that would allow the name entered to match to one of the names listed in the array. Both options only display the "invalid" message no matter what I enter. What would be the best choice to use the arrays to properly display the information ....

Im working on an assignment with the following instructions:
Create a Date class with the following capabilities:
a)Output the date in multiple formats such as MM/DD/YYYY June 14, 1992
b )Use overloaded constructors to create Date objects initialized with dates of the formats in part a).
You should only have 3 member data: integer month, integer day, and integer year. Also, you should have at least 2 constructors and 2 methods in your Date.java.
I'm working on a program that prompts the user to enter the year and first day of the year and displays the calendar table for that year on the console. For example, if the user entered the year 2005, and 6 for Saturday, Juanuary,1, 2005, the program should then display the calendar for each month of the year.
I have written the program and solved the problem for the most part. Only, I'm having terrific difficulty getting the output to properly format. I'm *almost* there. I'll post my program below and then output.
import java.util.Scanner; public class DisplayCalendar { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); System.out.print("Enter the year: "); int year = scanner.nextInt();
I have to create a method to find the current month with the input being a number of milliseconds using System.currentTimeMillis(). Now I was able to solve the problem with the following extremely cumbersome method:
public static int monthLeap(long ms) { int result = 0; int jan = 31, mar = 31, may = 31, jul = 31, aug = 31, oct = 31, dec = 31; int apr = 30, jun = 30, sep = 30, nov = 30; int feb = 28; int febLeap = 29;
[Code] ....
I first go through a loop that goes through all the years and subtracting the number of days of a normal year or a leap year in milliseconds from the total milliseconds. At the end I should have a rest value of milliseconds that represents the amount of milliseconds that have passed already this year. Out of this number I then find the month we are currently in.
My problem is that the above method is way to large and I get a checkstyle warning: "NPath Complexity is 12,288 (max allowed is 80)".
I know that this can somehow be solved with a for loop iterating through the time and counting up months until there is no more month left. My problem though is the different lengths of the months. If each month was the same I could just subtract the amount of days in each month from the rest value.
(Since I already got it down to <= 12 months, I shouldnt bother with the extra days to find the month. Yet if I want to find the month when the date is the first or last day of the month it is important to be very precise) ....
I have created an enumerated data type that represents months. In my program I have asked the user for the month. I hold the month entered by user into a string variable. From that string variable I'm trying to display the month using my enumerated data type. I know I can use if statements, but is there another simple way to do it?
import java.util.Scanner; public class demo { //Enum class called month that has constants in it representing months enum month{january,february,march,april,may,june, july,august,september, october,november, december};
Goal is to: Write a program that prompts the user to input an integer and then outputs both the individual digits of the number and the sum of the digits.
First I don't know where I made mistakes here, and the only error it finds right now is that str2 was not initialized and I cannot figure out where/when to initialize it.
import javax.swing.JOptionPane; public class DigitsAndSum { public static void main (String[] args) { String str1; String str2; int int1 = 0; int int2 = 0;
Write a class Month that represents one of the twelve months of the year. It should have three attributes for
the name of the month,
the number of days in the month, and
the birthstone.
Also add constructors and getter/setter methods to access the attributes.
You may use the following code to test your class.
Java Code:
import java.util.*; public class Month { // ADD CODE HERE!!! public static void main(String[] args) { Month[] months = new Month[12];
[Code] ....
So what I have added so far is (under public class month { :)
Java Code:
String monthName, monthBirthStone; int monthDays; public Month (String name, int days, String birthstone) { monthName = name; monthBirthStone=birthstone; monthDays=days; } mh_sh_highlight_all('java');
So I believe that is the constructor. I still do not understand several things:
What would I need the getter and setter for?
I tested it using just the above code, and using month 1 I got:
Month@5a1cfb56
This makes sense as I obviously didn't do anything in order to get it in a String format for the array. But I do not understand this still - how would I get the constructor to output a string (to then be in the array?)

Detect a bug in Java, specifically in the Calendar class will getDisplayName method. I put in the message code showing the error. If the code is executed you can see that the month March be repeated 2 times jumping the month of February.
Code Example:
import java.util.Calendar; import java.util.Locale; public class BugInCalendarDisplayName { public static void main(String[] args) { Calendar aMonth = Calendar.getInstance(); aMonth.set(Calendar.MONTH, 0);
[Code] ....
Obtained results of the code execution:

I am not sure how to incorporate the rate per month and the three rate zones.
Problem: Electricity billing charges vary with the season and amount used.
Southwest Power and Light provides electricity at the basic rate of $ 0.10 per kilowatt for the months December through February, 0.12 per kilowatt for the months of March through May, and 0.15 per kilowatt for the remaining months.
Customer billing is divided into three rate zones: 0-350 kilowatts, 351 – 500 kilowatts, and above 500 kilowatts. Usage up to 350 kilowatts is billed at the basic rate. Usage between 350 and 500 kilowatts is billed at 10% above the basic rate. Above 500, billing is 25% above the basic rate. These surcharges apply only to the usage falling within the respective rate zone.
Create a method called mirrorImage, which takes two integer arrays as input parameters. You may assume that the two actual parameters have the same length. Your method should return true if the arrays are the reverse of each other. Otherwise mirrorImage should return false.
Examples:
data1:{1,2,3} data2:{3,2,1} ==> true

I'm pointing a place outside of the array or something
Write a program to maintain a list of the high scores obtained in a game. The program should first ask the user how many scores they want to maintain and then repeatedly accept new scores from the user and should add the score to the list of high scores (in the appropriate position) if it is higher than any of the existing high scores. You must include the following functions:
-initialiseHighScores () which sets all high scores to zero.
-printHighScores() which prints the high scores in the format: “The high scores are 345, 300, 234”, for all exisiting high scores in the list (remember that sometimes it won’t be full).
-higherThan() which takes the high scores and a new score and returns whether the passed score is higher than any of those in the high score list.
-insertScore() which takes the current high score list and a new score and updates it by inserting the new score at the appropriate position in the list
System.out.print("To begin, please enter 1 to choose stand tickets or 2 to choose terrace tickets for your party. "); int standOrTerraceTickets = aScanner.nextInt(); while (standOrTerraceTickets != 1 && standOrTerraceTickets != 2) { System.out.print("Invalid input. Please enter 1 for stand tickets or 2 for terrace tickets. "); standOrTerraceTickets = aScanner.nextInt(); }
Okay I thought I had this working properly so that when the user entered anything other than 1 or 2 they would keep getting an error invalid input, however, that only works when the user enters an integer. If the user enters anything other than a number, the program crashes. How does one prevent this from happening?
The assignment was to create 3 parallel arrays to make a student database.The first array will contain 4 digit student id's, the second a string array with student names, and the third array is student gpa's. The user is to receive a dialog box asking to enter the student id, and if the id is correct the user is to see the student name and grade. If the user input does not match any value in the student id array, the user is to receive a message stating invalid id. Here is the code I have so far.
For some reason no matter what the user enters, the information for the last array entry is displayed.
public class parallelStudent { public static int sequentialSearch(int[] array, int value) { int index; //loop control variable int element; //element the value is found at boolean found; //flag indicating search results
