## 流式布局 ##

public class TestFlowLayout { 
        public static void main(String[] args) { 
            Frame frame = new Frame();
            Button button1 = new Button("button1");
            Button button2 = new Button("button2");
            Button button3 = new Button("button3");
            //设置为流式布局
            // frame.setLayout(new FlowLayout());
            frame.setLayout(new FlowLayout(FlowLayout.LEFT));//设置靠左显示
            frame.setSize(200,200);
            frame.add(button1);
            frame.add(button2);
            frame.add(button3);
            frame.setVisible(true);
        }
    }

## 边界布局 ##

**东西南北中**

public class TestBorderLayout { 
        public static void main(String[] args) { 
            Frame frame = new Frame("TestBorderLayout");
    
            Button east = new Button("east");
            Button west = new Button("west");
            Button south = new Button("south");
            Button north = new Button("north");
            Button center = new Button("center");
    
            frame.add(east,BorderLayout.EAST);
            frame.add(west,BorderLayout.WEST);
            frame.add(south,BorderLayout.SOUTH);
            frame.add(north,BorderLayout.NORTH);
            frame.add(center,BorderLayout.CENTER);
    
            frame.setSize(200,200);
            frame.setVisible(true);
        }
    }

## 表格布局 ##

public class TestGridLayout { 
        public static void main(String[] args) { 
            Frame frame = new Frame("TestGridLayout");
    
            Button btn1 = new Button("btn1");
            Button btn2 = new Button("btn2");
            Button btn3 = new Button("btn3");
            Button btn4 = new Button("btn4");
            Button btn5 = new Button("btn5");
            Button btn6 = new Button("btn6");
    
            frame.setLayout(new GridLayout(3,2));
    
            frame.add(btn1);
            frame.add(btn2);
            frame.add(btn3);
            frame.add(btn4);
            frame.add(btn5);
            frame.add(btn6);
    
            frame.pack();
            frame.setVisible(true);
        }
    }
