Answer 1

What does myFrame.this mean? I looked in the JFrame
class, and there is no 'this' field listed.
Shouldn't that just be MyFrame?"this" always refers to the current instance of the current object, right? So instead of:
  setTitle("Hello World");you can do something like:
  this.setTitle("Hello World");(Although, why would you?)
But, let's suppose you do something like this:
  public class MyClass {
    private String test = "test1";
    private class ThreadEntryPoint implements Runnable {
      private String test = "test2";
      public void run() {
        System.out.println("test = " + this.test);
      ThreadEntryPoint entryPoint = new ThreadEntryPoint();
      entryPoint.run();
      ...Is this going to print test1 or test2? The answer is "test2", since that's the "test" variable defined in the inner class. But, since ThreadEntryPoint was not declared as a static class, if the inner class didn't have a "test" variable, the reference to "test" could refer to the outter variable. If you remove the "test2" variable in the code above, it will still compile and print "test1".
But what if you wanted to print "test1" without removing "test2"? This is where the mechanism you are inquiring about comes in; it allows you to reference variables in outter classes which are occluded by variables in the inner class. So, you could write something like:
    System.out.println("TheadEntryPoint.test = " + TheadEntryPoint.this.test);
    System.out.println("MyClass.test = " + MyClass.this.test);
