Answer 1

this in

this.dispose();

refers to the MouseAdapter , hence the compilation errors you are seeing.

You need to invoke dispose on the JFrame

JFrameClassName.this.dispose();

Also consider using a JDialog rather than a JFrame as the second window. Read The Use of Multiple JFrames, Good/Bad Practice?

Answer 2

You should write

YourClassName.this.dispose();

which points to your jframe .
