java - 为什么代码无法访问？

Question

以下内容在“out.close();”上给我一条“代码无法访问”消息我找不到问题，因为它与我运行过的其他有效代码或多或少相同!

import java.io.*;
import java.net.*;

public class MyClient {
    private static String SERVER = "127.0.0.1";
    private static Integer PORT = 8765;
    public static void main(String[] args) throws IOException {
        // Connect to the server and create the writer and reader
        Socket socket = new Socket(SERVER,PORT);
        PrintWriter out = new PrintWriter(socket.getOutputStream(),true);
        BufferedReader in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
        // Loop forever
        while(true) {

            out.println("Question:");
            String sum = System.console().readLine();
            out.println(sum);

            String line = in.readLine().trim();
            if(line==null || line.startsWith("Finished")) {
                socket.close();
                return;
            }
            else if (line.startsWith("My answer is: ")){
                System.out.println(line);
                String message = System.console().readLine();//correct or wrong!!
                out.println(message);
            }       
        }
        // Close the in and out and socket
        out.close();
        in.close();
        socket.close();
    }
}

您正在从 while 循环中执行return。您应该改为break。
