import java.awt.Frame;
public class TestFrame
{
    public static void main(String[] args)
    {
        Frame frame = new Frame();
        //frame.setSize(500, 300);
        frame.setBounds(50,50, 500,300);
        frame.setTitle("Hello Java GUI");
        frame.setVisible(true);
    }
}

二 能设置背景色的窗口

1 代码

import java.awt.Color;
import java.awt.Frame;
class TestFrameColor extends Frame
{
    public TestFrameColor() {
        //设置标题
        this.setTitle( "Hello Java GUI" );
        //设置大小可更改
        this.setResizable( true );
        //设置大小
        //this.setSize(300,200);
        //设置大小及窗口顶点位置
        this.setBounds(50,50,500,300);
        //设置背景颜色
        this.setBackground(Color.green);
        //显示窗口
        this.setVisible(true);
    }
    public static void main(String[] args)
    {
        TestFrameColor colorFrame = new TestFrameColor();
    }
}

三 能关闭的窗口

1 代码

import java.awt.Frame;

        Frame frame = new Frame();
        frame.setSize(500, 300);
        frame.setTitle("Hello Java GUI");
        frame.addWindowListener(new WindowAdapter() {
            public void windowClosing( WindowEvent e ) {
                System.exit(0);
            }
