package com.dryant.lesson1;import java.awt.*;public class TestFlowLayout {public static void main(String[] args) {Frame frame = new Frame();Button button1 = new Button("bt1");Button button2 = new Button("bt2");Button button3 = new Button("bt3");Button button4 = new Button("bt4");Button button5 = new Button("bt5");//frame.setLayout(new FlowLayout());设置流式布局frame.setLayout(new FlowLayout(FlowLayout.LEFT));//设置流式布局左对齐frame.setSize(200,200);frame.add(button1);frame.add(button2);frame.add(button3);frame.add(button4);frame.add(button5);frame.setVisible(true);}
}

二、东西南北中布局

package com.dryant.lesson1;import java.awt.*;public class TestBorderLayout {public static void main(String[] args) {Frame frame = new Frame();///frame.setLayout(new BorderLayout());frame.setSize(500,500);Button button1 = new Button("east");Button button2 = new Button("按钮西");Button button3 = new Button("按钮南");Button button4 = new Button("按钮北");Button button5 = new Button("按钮中");frame.setVisible(true);frame.add(button1,BorderLayout.EAST);frame.add(button2,BorderLayout.WEST);frame.add(button3,BorderLayout.SOUTH);frame.add(button4,BorderLayout.NORTH);frame.add(button5,BorderLayout.CENTER);}
}

三、表格布局

package com.dryant.lesson1;import java.awt.*;public class TestGridLayout {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("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.setVisible(true);frame.setSize(300,300);}
}
