		f.setSize(400, 600);//Set the window size
		f.setLocation(500,50);//Set the window display location
		f.setVisible(true);//Display the window
		
		Button but = new Button("my button");//If the button is set to Chinese, garbled characters may appear
		f.setLayout(new FlowLayout());//The default is a border layout (the button is huge), so you need to set the layout in the main panel
