Compiling problem???

When I compile any Java program wit 'javac' its splits the main class file into different parts ( ex. MyClass.class, MyClass$1.class, and so on ) Then when I load them on the web ( they are for an applet ) the webshell makes the '$' a '_' because '$'s aren't aloud!! My javac didn't used to do that. Why is it? Any ideas????

Not sure about the web part but the $'s are produced by the compiler to mark the classes or interfaces within the inheritance heirachy. For instance the following code should produce the following class files when compiled.

TopLevelClass$NestedTopLevelClass$NestedTopLevelClass1.class
TopLevelClass$NestedTopLevelInterface1.class
TopLevelClass$NestedTopLevelClass.class
TopLevelClass.class

Code:

---

public class TopLevelClass {
  static NestedTopLevelClass{
 
  interface NestedTopLevelInterface1{
  }
 
  static class NestedTopLevelClass1
  implements NestedTopLevelInterface1{
    }
  }
 }

---

SomeClass$1.class is for the first anonymous nested class you declare, $2 for the second etc.
So

Code:

---

class MyClass
{
  JButton button = new JButton();
  public MyClass() {
    button.addActionListener(new ActionListener() {
      public void actionPeformed(ActionEvent e) {
      }
    } );
  }
}

---

results in
MyClass.class
MyClass$1.class

ahhh i see... cuz i was using:

Code:

---

addWindowListener( new WindowAdapter()
{
    public void windowClosing( WindowEvent e )
    {
        //...
    }
} );
