I'm trying to code a little text RPG. I've made a little "personality test", with 4 questions (answers a b c), where every letter stands for a type of personality. The analysis of the result is simple counting of the answers, if you have 3 answers a (4 questions), then a has won. If 2 on a, and 2 on b, a simple Random method shows weather result a or b.
Now... the test should give you a "partner" (imagine the pokemon game with 3 different starter pokemon). I have now 3 string variables, like 3 different partners. They are all declared somewhere outside, but i only need one later.
Like...the test is completed, you have your partner and how can i make now that the program is just showing me my partner? Like...when i type " System.out.println(partner); " (outside of the test loop! ) that i only get the one i got through the test?
I was trying to declare in every loop the partner String with every result. But outside the loop java isn't recognising that String, bcs...ofc...it was declared for the loop. So i had in every if or else if clause a " String partner = anwsA;" and answB and answC, thats why i cant declare them outside.
Short: i need a partner String variable that could have 3 possible results... i jut need one
I saw an example where an (inner)class is declared inside the main method, this is correct or not and why/when it's reasonable to use?so smth like this
public class myClass() { public static void myMethod(myInnerClass obj) { if (obj.method())
Where usually to instantiate and declare variables to be used in a loop. If you declare it outside to be used in the loop it will still be there when the loop is done, never to be used again and is just sitting there taking up memory. However, if you declare it inside the loop, you have the issue of it constantly creating space for said variable, but once it's out of scope it's gone. Is there any advantage performance wise to doing it either way?
I am trying to print a loop inside an array of a greater size than the loop itself. Like for example I have an array of size 7 but it has only 3 elements.
now what I want to do is print these three numbers in a loop so that my array[3]=2;array[4]=3;array[5]=4 ...... till the last one. Also the array could be any size and not just 7.
Here's the code: it's while loop inside a for loop to determine the proper length of a variable:
for (int i = 0; i < num; i++) { horse[i]=new thoroughbred(); boolean propernamelength = false; while (propernamelength==false){ String name = entry.getUserInput("Enter the name of horse "
[code]....
I was just wondering what was going on here -- I've initialized the variable, so why do I get this message? (actually the carat was under the variable name inside the parentheses.
Here's what "Why doesn't this work?" question. It concerns a small method which is part of a card game.
I'm trying to check a condition from a section of an array, without a predetermined number of times any given call to this method will require a check. How much of the array I'm checking could vary greatly.
Is it at all possible to nest a for loop yielding a variable number of boolean && conditions inside an if? Am I just missing the right bracketing or is this nesting (if that's the word) even possible in the language?
To clarify, below is broken code. Compiler isn't letting me accomplish this goal as I envision it.
public boolean isFlanking() { boolean f; int reach = Math.abs(selectorX - targetX); if(rival.getDeck()[selectorX].getPile().isEmpty() == true &&
Basically the problem is I've been trying to loop my switch (if this is even possible) until the user enters a correct number between 1 and 4. But for some reason when the user enters a correct number (1,2,3,4) the loop runs again. Even when the user enters a wrong number the switch ignores the default and repeats what is in the do.
Am I just trying to loop something that cannot be looped or have I gone?
I made this calculator in C++ and it worked wonderful so I decided to make it in java. When I run the program it gives me no errors but my if statements inside my while loop don't work
import java.util.Scanner; public class ohmlaw { public static void main(String args[]) { float current; float resistance; float voltage; String calchoice = new String(); Scanner cc = new Scanner(System.in);
cannot break from while loop. Whenever I am trying to exit from startCustomerManagement-> backEnd() -> mainScreen()..It gets stuck between mainScreen and backEnd screen. However I can exit from backEnd()->startCustomerManagement() screen

I have used netbeans to build my app. So there creating jTable is out of my control as that part was inside auto-generated code. I have just used the jTable.setValue().
My problem is, above method is inside a button click event. Updated values not displaying until the loops ends.
I can't figure out how to have all of the random characters generated to go into the String. Below I can only get the last character to covert over to a String.
System.out.println("Original random character string:"); String printingString = "a"; for (int i = 0; i < 50; i++)//loop to obtain 50 random characters { char randomChar = (char) ((Math.random() * 255) +32); System.out.print(randomChar); printingString = Character.toString(randomChar); } return printingString; }
Here, I want to avoid using the line **return"";** and instead return all of the values I output with **System.out.println();**
I have tried using a **StringBuilder** method, but this outputs nothing when I run my test program. I am guessing that StringBuilder must work differently in a while loop, but I can't find how!

public String toString(){ int topLine = size; int topCurrentLine = size; int bottomLine = 1; int bottomCurrentLine = size;
The code is supposed to insert HTML formatting on a specified string. (i.e o<b>the</b>r )Most of the code works correctly as I verified the outputs without a while loop. The loop is causing a string out of bounds error. I've tried adding the if statement and also formatting the (result += line) nothing is getting appropriate results...
public static String addFormat(String webpage, String toMatch, String format) { String result = ""; String insert = ""; format = format.toLowerCase(); switch (format){ case "bold": insert = "<b>" + toMatch + "</b>";
The problem is to figure out the number of cartons needed to box up the strawberries picked by the farmer and his wife. The farmer picks 8.4 lbs per hour and the wife pick 10.8 pounds per hour. They pick from 8 am until 4Pm (8 hours). You can put 20 pounds per box.I understand the word problem and how to declare and initialize variables. I'm just confused how to display the math into java to solve it.
Write a program that declares and concatenates various strings. Declare strings for your first name, middle initial and last name, along with one for your address, city, state and zip. Make an additional string called firstLine, which will be a concatenation of first name, space, middle initial, period, space, and last name. Assign each of these strings a value, and then print the information in the following format:
First Line (First name Middle initial (period) Last name)
Address
City, State
Zip
For example:
John Q. Public
1234 Any Street
Cleveland, Ohio
44101
Now reassign the strings in the same program (Do not create a separately compiled program!) and repeat the printout for different information. When you are finished, your program will print out two groups as above.
The information should be placed into the seven separate strings, then a first line should be formed by concatenating first name, space, middle initial, period, space, and last name. The city and state line should be formed by printing city followed by a comma, a space, then the state (NOT by concatenation). This is so you can see different ways of making lines."
I have a jtable which i want to put an array into... and Really don't know how.. I dont want to use array list mainly because it looks way to complicated so there must be some other way using defaultablemodel but i dont know how..
So here's my code: just a snippet which includes the testing of the jtable
I want to declare a 2 dimensional array in java which has 3 column and unlimited number of rows, i want to give a special name to each column . The type of first column is string second one is int and the last one is string
Column1_name Column2_name Column3_name String value Int value String value . . . . . .
import java.util.Scanner;//Imports Scanner public class operadoreslogicos//imports a public class { public static void main (String [] args)//defines the state of a class { Scanner input = new Scanner (System.in);//Inputs a scanner to read user //keyboard boolean cierto = true,// Declares variables as boolean and applies a value
[Code] .....
The word string is supposed to turn purple when I type it, but it just stays normal, so it doesn't declare hello and bye as variables.
