JAVA实现远程录屏或广播屏幕

最近网络编程课到了结尾，老师让写一个大作业，运用的就是JAVA的网络支持写一个东西，有写网络聊天室，斗地主什么的，我就写了一个录屏昨天通过了验收，废话不多讲，直接上代码：

客户端：接收服务端发送的信息；

public class ReceiveImages extends Thread{

public String IP;

public static void main(String[] args){

public ReceiveImages(BorderInit frame,String IP)

try {
socket = new Socket(IP,12122);
DataInputStream ImgInput = new DataInputStream(socket.getInputStream());
ZipInputStream imgZip = new ZipInputStream(ImgInput);

imgZip.getNextEntry(); //到Zip文件流的开始处
Image img = ImageIO.read(imgZip);  //按照字节读取Zip图片流里面的图片
frame.jlbImg.setIcon(new ImageIcon(img));
System.out.println("连接第"+(System.currentTimeMillis()/1000)%24%60+"秒");
frame.validate();
TimeUnit.MILLISECONDS.sleep(1);// 接收图片间隔时间
imgZip.close();

} catch (IOException | InterruptedException e) {
System.out.println("连接断开");
}finally{
try {
socket.close();
} catch (IOException e) {}
}
}
}

}

//Client端窗口辅助类，专门用来显示从教师端收到的屏幕信息

class BorderInit extends JFrame

{

private static final long serialVersionUID = 1L;

public JLabel jlbImg;

private boolean flag;

public boolean getFlag(){
return this.flag;
}
public BorderInit()
{

this.flag=true;
this.jlbImg = new JLabel();

this.setTitle("远程监控IP:"+"127.0.0.1");
this.setSize(1366, 768);
this.setAlwaysOnTop(true);  //显示窗口始终在最前面
this.add(jlbImg);
this.setLocationRelativeTo(null);
this.setExtendedState(Frame.MAXIMIZED_BOTH);
this.setDefaultCloseOperation(DISPOSE_ON_CLOSE);
this.setVisible(true);
this.validate();

//窗口关闭事件
this.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
flag=false;
BorderInit.this.dispose();
System.out.println("窗体关闭");
System.gc();
}
});
}

}

服务端：发送数据

第一次在这里添加代码不太熟悉，以上就是这个功能的实现，用的NetBeans画的窗体，窗体的图片就不再上传了，画的简单程度谁用了谁知道，就是这样，拿走的记得说一下(●’◡’●)；
