在线网络速度测试JAVA程序（二）：GUI客户端

在jperf.java程序中，实现了控制台模式的服务端和客户端程序；本文中实现了GUI图形窗口的客户端，为接下来WEB中使用的applet打下基础。以前用JAVA都只是做B／S开发，所以这是第一次写图形界面的程序，因此，重温了《JAVA核心技术卷一》的第7－9章节。

jperfwin.java

            {
                appframe frame=new appframe();
                frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

            }
        });
    }

}

编译代码：javac *.java

运行程序：java jperfwin，程序界面如图，实现的功能其实和控制台是一样的，都是调用jperf.java类执行测试。
