3种布局管理器

  1. 流式布局
  2. 东西南北中
  3. 表格布局
    流式布局：
package com.mingmao.gui.amt;

import java.awt.*;

public class TestFlowLayout {
    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");

        //设置为流式布局
        //frame.setLayout(new FlowLayout());//默认是居中
        //frame.setLayout(new FlowLayout(FlowLayout.LEFT));
        frame.setLayout(new FlowLayout(FlowLayout.RIGHT));

        frame.setBounds(100,100,500,500);

        //把按钮添加上去
        frame.add(button1);
        frame.add(button2);
        frame.add(button3);

        frame.setVisible(true);
    }
