BorderLayout
fm.add(bt1, bd.EAST);     <==位置需用大寫

還蠻有美感的所以貼一下


 // AWT, Button類別

import java.awt.*;
import java.awt.event.*;


public class awttest extends Frame implements ActionListener
{
//static Frame fm=new Frame("Button class");
static Button bt1=new Button("1");   // 建立按鈕物件
static Button bt2=new Button("2");
static Button bt3=new Button("3");
static Button bt4=new Button("4");
static TextField tf1=new TextField("5");

public static void main(String args[])
{
awttest fm=new awttest();
BorderLayout bd=new BorderLayout();
fm.setLayout(bd);
fm.setSize(200,150);
bt1.addActionListener(fm);
fm.add(bt1, bd.EAST);   // 在視窗內加入按鈕
fm.add(bt2, bd.WEST);
fm.add(bt3, bd.SOUTH);
fm.add(bt4, bd.NORTH);
fm.add(tf1, bd.CENTER);
fm.setVisible(true);
}

public void actionPerformed(ActionEvent e)
{
int r1;
r1=(int) (Math.random()*49)+1;
System.out.println(r1);
