This is the problem:
while (j <= 6) {
jDiceResult.add(javax.swing.Box.createGlue());
}
With this line, you create a infinite loop, because you check whether j<=6 but don't change the value of j, so j<=6 is always true.
I guess you want to change while to if.
I guess:
while (j <= 6) {
jDiceResult.add(javax.swing.Box.createGlue());
}
I think may be it should be:
if (j <= 6) {
jDiceResult.add(javax.swing.Box.createGlue());
}

I just want to ask if I can change the text in radio button.
For example:
here in the picture if I put a number, it will show the number factors at the radio button. ( the factor 1 will just show in Jlabel and the rest of the factor will show at the Radio button) the problem part at the private void checkbtnActionPerformed(java.awt.event.ActionEvent evt) I already tried to use .setText() but I think this will not work for radio button or button group. Is there another way to do that

I've built a Higher/Lower game, using the Swing library. When I run the code I don't get any errors or warnings. The problem appears when I try running the code, the window is empty, not the way it should be.
I use NetBeans to program.There are 2 different files in my project, here is the code...
HiLoGUI.java:
import java.awt.Dimension;
import javax.swing.*;
public class HiLoGUI extends JFrame {
private JTextField txtGuess;
private JLabel outputLabel;
private int theNumber;
public void newGame() {
theNumber = (int)(Math.random() * 100 + 1);
}
public void checkGuess() {
String guessText = txtGuess.getText();
String message = "";
int guess = Integer.parseInt(guessText);
if (guess < theNumber) {
message = guess + " is too low. Try again.";
}
else if (guess > theNumber) {
message = guess + " is too high. Try again.";
}
else {
message = guess + " is correct. You win!";
}
outputLabel.setText(message);
}
public static void main(String[] args) {
HiLoGUI theGame = new HiLoGUI();
theGame.newGame();
theGame.setSize(new Dimension(450,300));
theGame.setVisible(true);
}
}
The window should look like this:

EDIT2:
I've changed the main class of HiLoGUI.java
I was creating a wrong object.
New main:
public static void main(String[] args) {
HiLoJFrame theGame = new HiLoJFrame();
theGame.newGame();
theGame.setSize(new Dimension(450,300));
theGame.setVisible(true);
}
Now it claims that I need to create that method (newGame) in the JFrame file.
You are calling a method from the wrong class, according to the Swing docs, it is not needed to create a new JFrame object, so setting its visibility is enough. Check this out: How To Call JFrame from another Java class
I am Currently building a GUI for a tic tak toe game and i have finished it all, however when I tried to run it failed so I checked the code to find the problem and the only one i can currently find is that initComponents is red lined and I am Having a hard time finding out why.
I am currently new to Java and have only started coding recently so any assistance in this will be very appreciated.

Any testCase you can apply like proper working , (actual== expected Result) etc.
You can't test the GUI with JUnit. You can only test the methods.
For example you have a JButton with an actionListener witch calls the method calculate(1, 1):
JButton showDialogButton = new JButton("Text Button");
showDialogButton.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
calculate(1, 1);
}
});
private int calculate(int n1, int n2){
return n1 + n2;
}
Now, You cant test the JButton but you can test the method "calculate". We know that calculate(1, 1) will return us 2 so we test it:
assertEquals(2, calculate(1, 1));
This means, that you cannot "press the button with JUnit" but you can test the action the button does.
I have a series of radio buttons generated as an array and displayed in a jPanel.
I want a series of checkboxes in a second panel to be enbled when the radio buttons are in output state but not in the input (input or output are the radio choices).
I want to call the checking state method whenever any of the radiobuttons states change but don't know how to do this as they are created in an array.
Currently the method is called only when the radio button panel is actually clicked.
