当我在 Ubuntu 中使用 Java JDK 在终端中运行该程序时,如何使该程序退出?
我想在这个程序运行时输入“结束”,但我无法让它工作。它监听客户端并调用一个线程来为新客户端创建一个套接字。我不知道如何使这个程序结束。我什么都试过了。
我昨天开始学习java。请帮我....
import java.net.*; //jave lib
import java.io.*; //io lib
public class MultiServerConnections { //initiate class
public static void main(String[] args) throws IOException {
int portNum = 5342; //set server port number
boolean listen = true;
System.out.println("Listening for Connections"); //print message
ServerSocket server_Socket = null; //set server_Socket to null
try {
server_Socket = new ServerSocket(portNum); //set server port
} catch (IOException e) {
System.err.println("Port " + portNum + " is unavailable"); //port is taken error
System.exit(1);
}
BufferedReader stdIn = new BufferedReader(new InputStreamReader(System.in)); //set reader
String input;
//while (TCPglobals.checkRequests){
while (listen == true){
new MultiServer(server_Socket.accept()).start();
input = stdIn.readLine();
//if(TCPglobals.checkRequests == false) //|| (input = stdIn.readLine()) == "end")
if(input == "end") {
System.out.println("end connection?");
System.exit(1);
}
}//while
server_Socket.close(); //close server socket
}
}
