**1.流式布局**

public class TextFlowLayout {
        
        public static void main(String[] args) {
        
            Frame frame = new Frame();
            //组件-按钮
            Button button1 = new Button("button1");
            Button button2 = new Button("button2");
            Button button3 = new Button("button3");
            frame.setVisible(true);//设置可见性
            frame.setSize(200,200);//设置初始大小
            frame.setLocation(200,200);//设置初始位置
            //设置流式布局
            //这里选择CENTER三个按钮居中
            frame.setLayout(new FlowLayout(FlowLayout.CENTER));
           //把按钮添加上去
            frame.add(button1);
            frame.add(button2);
            frame.add(button3);
            //监听事件 监听窗口关闭事件 System.exit(0);
            //适配器模式
            frame.addWindowListener(new WindowAdapter() {
        
                @Override
                public void windowClosing(WindowEvent e) {
        
                    System.exit(0);
                }
            });
        }
    }

**2.东西南北中布局**

public class BorderLayout {
        
        public static void main(String[] args) {
        
            Frame frame = new Frame();
            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.setLocation(200,200);
            frame.setVisible(true);
    
            frame.setSize(200,200);
            frame.add(east, java.awt.BorderLayout.EAST);
            frame.add(west, java.awt.BorderLayout.WEST);
            frame.add(south, java.awt.BorderLayout.SOUTH);
            frame.add(north, java.awt.BorderLayout.NORTH);
            frame.add(center, java.awt.BorderLayout.CENTER);
            //监听事件 监听窗口关闭事件 System.exit(0);
            //适配器模式
            frame.addWindowListener(new WindowAdapter() {
        
                @Override
                public void windowClosing(WindowEvent e) {
        
                    System.exit(0);
                }
            });
        }
    }

**3.表格布局**

public class GirdLayout {
        
        public static void main(String[] args) {
        
            Frame frame = new Frame();
            Button btn1 = new Button("btn1");
            Button btn2 = new Button("btn2");
            Button btn3 = new Button("btn3");
            Button btn4 = new Button("btn3");
            Button btn5 = new Button("btn5");
            Button btn6 = new Button("btn6");
    
            frame.setSize(200,200);
            frame.setVisible(true);
            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();//java 自动排序
            //监听事件 监听窗口关闭事件 System.exit(0);
            //适配器模式
            frame.addWindowListener(new WindowAdapter() {
        
                @Override
                public void windowClosing(WindowEvent e) {
        
                    System.exit(0);
                }
            });
    
        }
    }

**4.三种布局的嵌套使用**

//建立四个面板，采用嵌套
    public class Text1 {
        
        public static void main(String[] args) {
        
            Frame frame = new Frame();
            //布局
            frame.setLayout(new GridLayout(2,1));
            //frame窗口基本功能
            frame.setLocation(200,200);
            frame.setSize(300,300);
            frame.setVisible(true);
            frame.setBackground(Color.BLUE);
            //四个面板
            Panel p1 = new Panel(new BorderLayout());
            Panel p2 = new Panel(new GridLayout(2,1));
            Panel p3 = new Panel(new BorderLayout());
            Panel p4 = new Panel(new GridLayout(2,2));
            //最外层为两行一列的窗口
    
            p1.add(new Button("btn1"),BorderLayout.EAST);
            p1.add(new Button("btn4"), BorderLayout.WEST);
            //Grid表格式会自动排序
            p2.add(new Button("btn2"));
            p2.add(new Button("btn3"));
            p1.add(p2, BorderLayout.CENTER);
            p3.add(new Button("btn5"), BorderLayout.EAST);
            p3.add(new Button("btn10"), BorderLayout.WEST);
            p4.add(new Button("btn6"));
            p4.add(new Button("btn7"));
            p4.add(new Button("btn8"));
            p4.add(new Button("btn9"));
            p3.add(p4, BorderLayout.CENTER);
            frame.add(p1);
            frame.add(p3);
            //监听事件 监听窗口关闭事件 System.exit(0);
            //适配器模式
            frame.addWindowListener(new WindowAdapter() {
        
                @Override
                public void windowClosing(WindowEvent e) {
