Thread: Send Int to Another Class Help

Hello!

I'm attempting to increment the correct answers of radio buttons in Window2.java then I am trying to pass the final value to Window3.java to display it in a JLabel. I have attached the files through zip

Window2.java
In earlier code I have
28. public int countCorrectAnswers;

64. countCorrectAnswers = 0;

	//create question 1 and it's radio buttons
		JLabel question1 = new JLabel("What's the title of the short story?");
 
		JPanel answers1 = new JPanel();
		question1Option1 = new JRadioButton("Camping Trip"); 
		question1Option2 = new JRadioButton("Camp Food");			//correct answer
		question1Option3 = new JRadioButton("Cooking Made Easy");
		question1Option4 = new JRadioButton("Food is Great when Camping");
 
		question1Group = new ButtonGroup();
		question1Group.add(question1Option1);
		question1Group.add(question1Option2);
		question1Group.add(question1Option3);
		question1Group.add(question1Option4);
 
		answers1.add(question1Option1);
		answers1.add(question1Option2);	//correct answer
		answers1.add(question1Option3);
		answers1.add(question1Option4);
 
	if (question1Option2.isSelected())
		countCorrectAnswers++;

The above occurs 5x for 5 questions



Window3.java

public class Window3 extends JFrame
{
	private JLabel results;
	private JPanel buttonPanel;
	private JButton button;
 
	private JMenuBar menuBar;
	private JMenu fileMenu;
	private JMenu aboutMenu;
	private JMenuItem exitItem;
	private JMenuItem infoItem;
 
	public Window3()
	{
	//	Set GUI information & layout; display window
 
		setTitle("Results of Short Story & Quiz");
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		setLayout(new BorderLayout());
 
		buildMenuBar();
 
 
	[B]// I want to access countCorrectAnswers from Window2.java in order to display in the following JLabel[/B]
 
		JLabel results = new JLabel("You answered " + countCorrectAnswers + " out of 5 correct. That is a ###%.");
		add(results, BorderLayout.CENTER);
 
		buildButtonPanel();
		add(button, BorderLayout.SOUTH);
 
		pack();
		setVisible(true);
	}

I have countCorrectAnswers defined and initialized in Window2.java

No, Window2.java should be the only location where the variable is defined as a public int

I need it printed in Window3.java

I receive the following compiler error:

----jGRASP exec: javac -g Window3.java

Window3.java:29: error: cannot find symbol
JLabel results = new JLabel("You answered " + countCorrectAnswers + " out of 5 correct. That is a ###%.");
^
symbol: variable countCorrectAnswers
location: class Window3
