本文介绍了三种Java AWT/Swing布局管理器：GridLayout使组件以表格形式排列；BorderLayout将容器分为五个区域；FlowLayout则按添加顺序从左到右排列组件。

javax.swing.BoxLayout

===================

java.awt.GridLayout

import java.awt.*;
import java.applet.Applet;
public class ButtonGrid extends Applet {
     public void init() {
         setLayout(new GridLayout(3,2));
         add(new Button("1"));
         add(new Button("2"));
         add(new Button("3"));
         add(new Button("4"));
         add(new Button("5"));
         add(new Button("6"));
     }
}

===================

java.awt.BorderLayout

import java.awt.*;

import java.applet.Applet;

public class buttonDir extends Applet {
   public void init() {
     setLayout(new BorderLayout());
     add(new Button("North"), BorderLayout.NORTH);
     add(new Button("South"), BorderLayout.SOUTH);
     add(new Button("East"), BorderLayout.EAST);
     add(new Button("West"), BorderLayout.WEST);
     add(new Button("Center"), BorderLayout.CENTER);

}
}
