getText(); problem

[The_Sponzy_Paradox]

I cannot seem to get my getText() and setText to work it throws these errors:

I cannot seem to get my getText() and setText to work it throws these errors:

Read up on scope of variables. Where do you declare the test variable? Based on this, where is the only place that the test variable is visible? If you want test to be visible in other methods of the class, where should it be declared?

Please let me know if this does or doesn't make sense.

Best of luck!

I declared the variable in my init() method I think so umm I cant say it makes much sense to me:confused:. That is why I am confused as to why it does not seem to function

here is all the references to the code:

public void init()
JTextField test = new JTextField();
//blah
test.setSize(inputheight, inputwidth);
test.setLocation(startingpoint, 0);
test.setText("vvcgmki~: ");
test.setForeground(Color.green);
test.setBackground(Color.black);
c.add(test);
test.addActionListener(this);

public void actionPerformed(ActionEvent e)
	{
		String input = test.getText();
		test.setText("Input Sucessful");
		test.setText(input);

	}

Please look at the code and comments here. Does this help you understand things better?

public class Fubar {
  // this guy is visible throughout the class
  private int privateClassVar = 0;
  
  public void methodA() {
    // this guy is *only* visible inside of methodA
    int methodAVar = 0;
  }
  
  public void methodB() {
    System.out.println(privateClassVar);  // no problem here
    System.out.println(methodAVar);  // BIG problem here!
                                  // methodB cannot see the var
                                  // that is hidden inside of methodA
  }
}

So I need to do something like this:

public class CoiGOctogon25 extends JApplet implements ActionListener
{
		int  appwidth, appheight, inputheight, inputwidth, startingpoint;
		//add in a dynamic meathod binding array
		JPanel Octogon_Panel = new JPanel();
		JTextField test = new JTextField();
		appwidth = getSize().width;
		appheight = getSize().height;
		inputheight = (int)(appheight * .33);
		inputwidth = appwidth;
		startingpoint = appheight - inputheight;
		Container c;

	public void init()
	{
		c.getContentPane();
		c.setBackground(Color.lightGray);
		Octogon_Panel.setLocation((startingpoint + 36), 0);
		c.add(Octogon_Panel);
		Octogon_Panel.repaint();
		test.setSize(inputheight, inputwidth);
		test.setLocation(startingpoint, 0);
		test.setText("vvcgmki~: ");
		test.setForeground(Color.green);
		test.setBackground(Color.black);
		c.add(test);
		test.addActionListener(this);
	}

	public void actionPerformed(ActionEvent e)
	{
		String input = test.getText();
		test.setText("Input Sucessful");
		test.setText(input);

	}

I still get this error:

C:\Users\Kyle\Documents\CoilGunOctogon25.java:29: <identifier> expected
appwidth = getSize().width;

what is the identifier that it is talking about

You can declare variables in the class and outside of methods/constructors, but that's about it. You can't do statements like that outside of methods/constructors/etc.

Applets are no different from other classes in this regard.
