我对Java线程有困难。在这个程序中,我希望它同时读取TCP和UDP,但是在我的代码中,只有当发送TCP请求时,代码才会进入UDP。使用Java中的线程进行套接字编程
我希望他们同时工作,任何人都可以帮助我吗?
这是我到目前为止有:
public class Newthreads {
ServerSocket socket;
DatagramSocket udpSocket;
private int id=1;
public Newthreads() throws IOException {
socket=new ServerSocket(9000);
udpSocket=new DatagramSocket(5000);
System.out.println("listening on 7000");
System.out.println("udp listening at 5000");
ClientServerThread clientThread=new ClientServerThread(socket);``
clientThread.start();
SlientServerThread e =new SlientServerThread(udpSocket);
e.start();
}
public static void main(String[] args) throws IOException {
new Newthreads();
}
}
class ClientServerThread extends Thread {
Socket clientSocket;
int child;
public ClientServerThread(ServerSocket conn) throws IOException {
//To change body of created methods use File | Settings | File Templates.
System.out.println("i m here");
clientSocket=conn.accept();
}
public void run() {
System.out.println("executing TCP");
}
}
class SlientServerThread extends Thread {
Socket conn;
DatagramPacket recvPacket;
private byte[] recvdata=new byte[10];
SlientServerThread(DatagramSocket tcpSocket) throws IOException {
recvPacket=new DatagramPacket(recvdata,recvdata.length);
tcpSocket.receive(recvPacket);
System.out.println("hey thread 2");
}
