布局练习：

一.

public class PracticePanelDemo {
    public static void main(String[] args) {
        Frame frame = new Frame();
        frame.setBounds(500,500,400,300);
        frame.setVisible(true);

        

    }
}

二.首先分上下布局

package lesson01;

import java.awt.*;

public class PracticePanelDemo {
    public static void main(String[] args) {
        //总的Frame
        Frame frame = new Frame();
        frame.setBounds(500,500,400,300);
        frame.setVisible(true);
        //分为上下结构
        frame.setLayout(new GridLayout(2,1));
       

        Panel panel01 = new Panel();


    }
}

三.先搞定上部分

panel01:

panel02:

import java.awt.*;

public class PracticePanelDemo {
    public static void main(String[] args) {
        //总的Frame
        Frame frame = new Frame();
        frame.setBounds(500,500,400,300);
        frame.setVisible(true);
        //分为上下结构
        frame.setLayout(new GridLayout(2,1));

        //四个面板  先设计面板 再将面板加入窗口中
        //东西南北中布局
        Panel panel01 = new Panel(new BorderLayout());
        //表格布局
        Panel panel02 = new Panel(new GridLayout(2,1));

        Panel panel03 = new Panel(new BorderLayout());
        Panel panel04 = new Panel(new GridLayout(2,2));

        //给面板添加组件、
        panel01.add(new Button("east"),BorderLayout.EAST);
        panel01.add(new Button("west"),BorderLayout.WEST);
        panel02.add(new Button("p2-1"));
        panel02.add(new Button("p2-2"));
        //上面ok
        panel01.add(panel02,BorderLayout.CENTER);
        frame.add(panel01);



    }
}

四.接着搞定下面部分

package lesson01;

import java.awt.*;

public class PracticePanelDemo {
    public static void main(String[] args) {
        //总的Frame
        Frame frame = new Frame();
        frame.setBounds(500,500,400,300);
        frame.setVisible(true);
        //分为上下结构
        frame.setLayout(new GridLayout(2,1));

        //四个面板  先设计面板 再将面板加入窗口中
        //东西南北中布局
        Panel panel01 = new Panel(new BorderLayout());
        //表格布局
        Panel panel02 = new Panel(new GridLayout(2,1));

        Panel panel03 = new Panel(new BorderLayout());
        Panel panel04 = new Panel(new GridLayout(2,2));

        //给面板添加组件、
        panel01.add(new Button("east-1"),BorderLayout.EAST);
        panel01.add(new Button("west-1"),BorderLayout.WEST);
        panel02.add(new Button("p2-1"));
        panel02.add(new Button("p2-2"));
        //上面ok
        panel01.add(panel02,BorderLayout.CENTER);
        frame.add(panel01);

        //同理搞定下面
        panel03.add(new Button("east-2"),BorderLayout.EAST);
        panel03.add(new Button("west-2"),BorderLayout.WEST);
        //利用for循环解决下面四个组件
        for (int i = 1; i <= 4; i++) {
            panel04.add(new Button("p4-"+i));
        }
        panel03.add(panel04,BorderLayout.CENTER);
        //下面ok
        frame.add(panel03);


    }
}

五.再加个鼠标监听事件，布局搞定

package lesson01;

import java.awt.*;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import java.awt.event.WindowListener;

public class PracticePanelDemo {
    public static void main(String[] args) {
        //总的Frame
        Frame frame = new Frame();
        frame.setBounds(500,500,400,300);
        frame.setVisible(true);
        //分为上下结构
        frame.setLayout(new GridLayout(2,1));

        //四个面板  先设计面板 再将面板加入窗口中
        //东西南北中布局
        Panel panel01 = new Panel(new BorderLayout());
        //表格布局
        Panel panel02 = new Panel(new GridLayout(2,1));

        Panel panel03 = new Panel(new BorderLayout());
        Panel panel04 = new Panel(new GridLayout(2,2));

        //给面板添加组件、
        panel01.add(new Button("east-1"),BorderLayout.EAST);
        panel01.add(new Button("west-1"),BorderLayout.WEST);
        panel02.add(new Button("p2-1"));
        panel02.add(new Button("p2-2"));
        //上面ok
        panel01.add(panel02,BorderLayout.CENTER);
        frame.add(panel01);

        //同理搞定下面
        panel03.add(new Button("east-2"),BorderLayout.EAST);
        panel03.add(new Button("west-2"),BorderLayout.WEST);
        //利用for循环解决下面四个组件
        for (int i = 1; i <= 4; i++) {
            panel04.add(new Button("p4-"+i));
        }
        panel03.add(panel04,BorderLayout.CENTER);
        //下面ok
        frame.add(panel03);

        frame.addWindowListener(new WindowAdapter() {
            @Override
            public void windowClosing(WindowEvent e) {
                System.exit(0);
            }
        });


    }
}
