Android - Looping Through Parse Data / Assigning To ArrayAdapter
Apr 24, 2015
I am looping through data in Android, using Parse data. I came up with this as a way to get user information; the larger goal is to create a model of data that I can use in an array adapter, so I can create a custom list view (as described here [URL] .... In the example, the data are hard-coded, not pulled from a database.
public static ArrayList<Midwifefirm> getUsers() {
//Parse data to get users
ParseQuery<ParseUser> query = ParseUser.getQuery();
query.orderByAscending(ParseConstants.KEY_PRACTICE_NAME);
query.findInBackground(new FindCallback<ParseUser>() {
[Code] ....
The intention is that for every user that does not have the type patient, collect this data about them, then store it in the arrayList.
On the return statement, though, there is an error: cannot return a value from a method with a void return type.
I may be over complicating this...read through various sources to get a model for this...in the end, I want to display a list of information about specific users, after the user makes a selection of a city...it would therefore display all the information about the medical practices in that city.
I'm just starting out with learning how to process/parse XML data in Java, following online code/tutorials. I am currently only printing out "catalog."
I am working on my second javafx program and I am getting confused. The program that I am writing is a payroll calculator. A secondary window opens at the start of the program where the user first enters the number of employees and clicks submit to save the number and to close this window. Then, the user begins to enters the employee information (first name, last name, pay rate and hours worked) when the user clicks the NextEmp button, I want the data in the text fields to be entered into arrays for later use, then clear the fields for the next use. I am running into 2 issues. The first is the close event for the secondary window that pops up. I cannot figure out the syntax. The second issue that I am running into is the loop to store the data into the arrays. I believe I am getting the text field data correctly, but I cannot figure out how to stop the loop until the NextEmp button is pressed again.
I'm programming an android app where I want to send large sets of data from an MySQL Table to the app and write this data to an SQLite database.So I know i have send an HttpRequest and I can send data with json, but how can I handle large datasets like tables?I think its no good idea to just concatinate a string together in php and then send it?
while (gamesPlayed<gameQty) { userChoice = JOptionPane.showInputDialog("Rock, Paper, or Scissors?"); //Determine winner for each game if (compChoice.equalsIgnoreCase(userChoice));
[Code] ....
It seems to circle through the loop gameQty times, without comparing.
In my JSP I need to retrieve some data from MySQL. I need to assign a "email" variable to the "WHERE" clause. The variable is retrieved from the session attribute. So far, I have this code:
<sql:query dataSource="${user}" var="result"> SELECT * from users where email = ${sessionScope.email}; </sql:query>
import java.util.Scanner; public class Try{ static String name; static int age; static Scanner a = new Scanner(System.in); static Scanner b = new Scanner(System.in); static Scanner c = new Scanner(System.in); public Try(String name, int age){
[Code] ....
I was trying to make a program that asks the user to create a person or a group of persons and assign names and age to them. So I made a constractor "Try" and a method "AskUser".in AskUser() I use a do/while loop where user is asked to input a name, an age and if he likes to create another person. Now how do I take the input data each time the loop runs, and send it to constractor to create new objects with it? And how these new objects will be called?
I am able to get output from my constructor when I place a loop inside of it. However when I try to access the private variable that I thought was set by the constructor I get nothing. When I check its size it is zero as well.
Java Code:
public class WinningHand extends PokerCalculator { private int p1Size; private int p2Size; private String[] p1Hand = new String[p1Size]; private String[] p2Hand = new String[p2Size];
I have a program that using one JFrame which opens one of two JDialog windows depending on which button is pressed.
How do I assign listeners to the buttons and fields on the JDialog window? I added listeners on the View end, but how do I process them? I tried adding the '..implements ActionListener" class in the main Controller but it does not recognize/hear anything.
I have been asked to write a library program that will keep record of books and the year it was published. The program should ask the user how many rows he wants accept the string input from the user and display them in rows and columns. This is how i code it
package multidimension; import java.util.Scanner; public class bookrecords { public static void main(String[]args){ //declaring a scanner variable Scanner input =new Scanner(System.in);
I have a txtfile which I read and go through. My question is what are the ways I could do to read a txtfile of words and assign an empty score to each of the word in it. So each word will have a 0 value. Later on I will manipulate the score but for now I want each word to have a 0 score.What I have at the moment is reading a text file full of words eg:
private void readtextfile() { try { Scanner rd = new Scanner( new File("filename")); List<String> lines = new ArrayList<String>(); while (sc.hasNextLine()) { lines.add(sc.nextLine());
[code]...
how to make each of the words to have a score of zero 0?
byte b = 100; it works (implicit conversion of implicit int literal 100 to byte.
But if you have a methodvoid bla(byte b){}
And want to invoke it with a literal (which is an int by default):bla(8) then there is no implicit conversion.
Is the byte b = 100; just an exception in Java? And is it the rule that one has to explicitely cast (narrow) integer literals when passing to smaller-than-int types?
I'm learning about inheritance and on this problem I first have to create a class where I get/set methods and get user input for the data fields.
I suppose I should know it at this point but I don't know how to get the users name when they input it. I copied the whole code but the issue is at line 51.
import javax.swing.JOptionPane; public class Order { private String customerName; private int customerNumber; private int quantityOrdered; private double unitPrice; private double totalPrice;
Write a program that asks the user for the low and high integer in a range of integers. The program then asks the user for integers to be added up. The program computes two sums:
The sum of integers that are in the range (inclusive), and the sum of integers that are outside of the range. The user signals the end of input with a 0.
Your output should look like this:
Sample input/output
In-range Adder Low end of range: 20 High end of range: 50 Enter data: 21 Enter data: 60 Enter data: 49 Enter data: 30 Enter data: 91 Enter data: 0 Sum of in range values: 100 Sum of out of range values: 151
This is my assignment and below is my code.
import java.util.Scanner; class InRangeAdder { public static void main(String[] args) { Scanner scan = new Scanner (System.in); int low, high, data=1, rangesum=0, outrangesum=0;
[Code] ....
The problem is that the program simply gives an output of 0 for both "rangesum" and "outrangesum". I don't quite understand why that is. Also i have a quick question, the program needs me to end the program when the value of data is 0 but in order to initialize it I need to give it a value. Usually I would give it a value of 0 like I have for rangesum and outrangesum but if I do the program does not run till the loop as it considers the value of data to be 0 and ends the program right away. What would be a work around to this and when do I need to have a value to initialize an integer? for example, I do not need a value for low and high. Is this because the program recognizes that a value is going to be defined but cannot do that for the other integers as they are inside a loop?
I have a program ive been working on and it works, but the flags in the runnables seem to shift the output down 1. for instance i commented playa3. start(); to see whats going on, if i just run playa1 i got no issues, as soon as i enable playa2, i get this output:
Game continues... Dealer places King and Queen on the table.
Game continues... Dealer places Queen and Ace on the table. Player one with 'Ace' places his card on the table. Player one with 'Ace' wins the current deal. King Queen
Game continues... Dealer places Queen and King on the table. Player two with 'King' places his card on the table. Player two with 'King' wins the current deal. Queen Ace
the second time the dealer deals, player one places his cards on the table when he was supposed to do that for the first deal which he didnt. the last line there, (king queen) is just a print statement that is referring to the dealers hand that, that iteration is responding too. below is my code, i
public class P5 { public static int i, count, dealerFirstCard, dealerSecondCard, player1, player2, player3; public static String cardSet [] = {"Ace","King", "Queen"}; public static volatile boolean dealerFinished= false; public static volatile boolean playersFinished= false;
I'm having some issues, trying to solve this problem in java. I want to print some election results, and i have to loop through a vector of objects and retrieve the partial sums of each party's seats for each constituency and the national results for each party. For now i can print the results per contituency, but i'm having problems in getting the national results. Like, adding the seats for labour party in Constituency A and B and C, etc, and print the sum. And do the same for conservative party.
This is what i have.
Java Code:
while (i < h.geral.size()) { show += "Constituency - " + ((Party) h.geral.elementAt(i)).getConstituency() + "
int x = 10; do{ System.out.print("value of x : " + x ); x++; System.out.print(""); }while( x + x == 22 );
When i put x+x==22 than it gives 2 values of x which are 10 and 11, they are wrong but when i put any other value like x+x==24 it just shows 1 value which is 10. I am not able to understand what mistake is there. I have been searching it for past whole month but didn't got any reason.
The player is defined as having 8 attributes which are in the array. The user enter attribute ratings that are restricted between 1 and 10. The total number of attribute points per player to allocate is 60. So my checks are that the inputted numbers are between 1 and 10 and the sum of them is 60. I continue to get an infinite loop when the code hits the if statement defining jamesTotalQuarter != 60. The code works however if the total is 60. What I want it to do is if the total != 60 revert back to the top of the code to allow the user to re-input their ratings. I've tried different combinations of continue and break statements without the outcome I'm looking for.
[public static void lebronJames() { // TODO Auto-generated method stub Scanner input = new Scanner(System.in);
//Declare an array to hold 8 intgers values int lebronJamesAttributes[] = new int[8]; int attribute = 0; System.out.println("Please allocate your attribute points for Lebron James in the following order. Your point allocations per attribute should be between 1 and 10. You have a total of 60 points to allocate"); System.out.println("-----------------"); System.out.println("Close Range" + "
I have written a small program that creates a loop that only fails to continue once we reach a StackOverflowError exception. It looks just like:
class MyFirstApp { static int counter; public static void main(String[] args) { counter++; System.out.println(counter + " in main."); roundAbout(); }
public static void roundAbout() { counter++; System.out.println(counter + " in roundAbout."); main( new String[0] ); } }
The idea of the program is to go between each method without using an object. Each time the method is entered the static int counter variable is incremented and outputted along with its respective loop. The loop does, however, fail eventually.
By calling the between the methods we build a tower of stack frames that eventually topples. The number of times this runs before the StackOverflowError occurs varies, though. Sometimes I get 6553, 6554 or something else close to these values.
Is there a way to pop a method of the stack or clear part of the stack so I can keep this going? I don't know where I would use this but it would be nice to know.
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 have date in string ex: 2014-08-08T17:38:58.316+05:30 and want to convert into 2014/08/08 17:38:58. I am using below code :
String date1="2014-08-08T17:38:58.316+05:30"; SimpleDateFormat formatter, FORMATTER; formatter = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"); String oldDate = "2011-03-10T11:54:30.207Z"; Date date = formatter.parse(oldDate.substring(0, 24)); FORMATTER = new SimpleDateFormat("dd-MMM-yyyy HH:mm:ss.SSS"); System.out.println("OldDate-->"+oldDate); System.out.println("NewDate-->"+FORMATTER.format(date));
this giving me required value, but when i replace oldDate with date1 it shows me exception that not parse to date. Actually i am getting date in string of 2014-08-08T17:38:58.316+05:30 which i need to convert into date 2014/08/08 17:38:58. To convert into date i am using below code :
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd/M/yyyy hh:mm:ss"); Date datecomp1 = simpleDateFormat.parse(String );
The issue is to convert 2014-08-08T17:38:58.316+05:30 into 2014/08/08 17:38:58.
I want to parse a java file (i.e., I need write some code which understand the content of a given java file--> the name of this java file will be entered as input). Then, after my code understand the content of the given java file, map this java file into another target language or platform. the output from my code is the new file which can run on the target language or platform.in the current state, I want to write some code which can understand a java file and can parse its content and display it on the console.
