 				//代表dialog的父窗口么。
 				dialog.setTitle("Antoher");

 				//这个Frame代表什么呢。
 				//代表dialog的父窗口么。
 				dialog.setTitle("Hello");
 				dialog.setVisible(true);
 				dialog.setLocation(300, 200);

 			//			dialog.setVisible(false);
 						//为什么执行上面的语句，系统会提示我需要将dialog修改成final;
 						//如何设置关闭该对话框？
 						//dialog没有destory或者exit方法。
 						//而且
 						dialog.dispose();
 					}
 					
 				});
 			}
 
 			@Override
 			public void mousePressed(MouseEvent e)
 			{
 				System.out.println("Pressed: "+e.getButton());
 				
 			}
 
 			@Override
 			public void mouseReleased(MouseEvent e)
 			{
 				System.out.println("Release: "+e.getButton());
 				
 			}

 			@Override
 			public void mouseExited(MouseEvent e)
 			{
 				// TODO Auto-generated method stub
 				
 			}
 			
 		});
 		
 	}
 }
 

such as the above code :

 button.addActionListener(new ActionListener(){
 
 			@Override
 			public void actionPerformed(ActionEvent e)
 			{
 				// TODO Auto-generated method stub
 				System.out.println("ActionPerformed:"+e);
 				final Dialog dialog = new Dialog(new Frame());
 				//这个Frame代表什么呢。
 				//代表dialog的父窗口么。
 				dialog.setTitle("Antoher");
 				dialog.setVisible(true);
 				dialog.setLocation(100, 200);
 				dialog.setSize(300, 300);
 				dialog.setBackground(Color.BLUE);
 			}
 			
 		});
 

and

 public void mouseClicked(MouseEvent e)
 			{
 				// TODO Auto-generated method stub
 				System.out.println("Click: "+e.getButton());
 				final Dialog dialog = new Dialog(new Frame());
 				//这个Frame代表什么呢。
 				//代表dialog的父窗口么。
 				dialog.setTitle("Hello");
 				dialog.setVisible(true);
 				dialog.setLocation(300, 200);
 				dialog.setSize(300, 300);
 				dialog.setBackground(Color.BLUE);
 				
 				dialog.addWindowListener(new WindowAdapter(){
 
 					@Override
 					public void windowClosing(WindowEvent e)
 					{
 						// TODO Auto-generated method stub
 				//		super.windowClosing(e);
 						System.out.println(e);
 			//			dialog.setVisible(false);
 						//为什么执行上面的语句，系统会提示我需将dialog修改成final;
 						//如何设置关闭该对话框？
 						//dialog没有destory或者exit方法。
 						//而且
 						dialog.dispose();
 					}
 					
 	

seemingly will play the same effect.
------ Solution ---------------------------------------- ----
usually I have used actionlistener rarely used mouseClick, specific differences is not clear , it may depend on the source code for these two classes , and passing under study
------ Solution - ------------------------------------------
button ActionListener either response has focus , press the Enter / spacebar , and can respond to mouse clicks.

The best option is to use ActionListener.
------ For reference only -------------------------------------- -
better choice is to use the Action to create a JButton.
