        //calling the constructor of the socket class
        Socket socket = new Socket();
        int tc=89;
        //sets the traffic class for this socket
        socket.setTrafficClass(tc);
        //getTrafficClass() returns the traffic class
        System.out.println("Traffic class: "+socket.getTrafficClass());
    }
}

输出

import java.io.IOException;
import java.net.*;
public class JavaSocketGetTrafficClassExample2  {
    public static void main(String[] args) throws IOException {
        //calling the constructor of the socket class
        Socket socket = new Socket();
        //closing the socket
        socket.close();
        int tc=89;
        //sets the traffic class for this socket
        socket.setTrafficClass(tc);
        //getTrafficClass() returns the traffic class
        //will return an exception, as the socket is already closed
        System.out.println("Traffic class: "+socket.getTrafficClass());
    }
