Question

我在netbeans中创建一个java客户端/服务器套接字程序，它应该接受一个数字，然后返回平方根/平方数。它允许我输入一个数字，然后我得到以下声明：客户端中发现异常：java.util.NoSuchElementException。

我不确定为什么会这样做，请帮忙！

这是我的两个类的代码：

客户端：

package question1.clientserver;

import java.net.*;
import java.io.*;
import java.util.Scanner;

public class Client {

 public static void main(String[] args) throws IOException {
    try {
        int number, temp;
        Scanner sc = new Scanner(System.in);
        Socket s = new Socket("127.0.0.1", 1452);
        Scanner sc1 = new Scanner(s.getInputStream());
        System.out.println("Enter any number to be squared");
        number = sc.nextInt();
        PrintStream p = new PrintStream(s.getOutputStream());
        p.println(number);
        temp = sc1.nextInt();
        System.out.println(temp);
    } catch (Exception e) {
        System.out.println("Exception found in Client: " + e);
    }
}
}

这是我的服务器代码

package question1.clientserver;

import java.io.IOException;
import java.io.PrintStream;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.Scanner;

public class Server {

public static void main(String[] args) {
    while (true) {
        System.out.println("Waiting for connection, please stand by...");

        try {
            int number, temp;
            ServerSocket s1 = new ServerSocket(1452);
            Socket ss = s1.accept();
            System.out.println("Connection has been established");
            Scanner sc = new Scanner(ss.getInputStream());
            number = sc.nextInt();

            temp = number * number;

            PrintStream p = new PrintStream(ss.getOutputStream());

            p.println(temp);
        } catch (Exception e) {
            System.out.println("Exception in Server while creating connection" + e);
        }

    }
}
}
}

如果您有任何想法或建议，请告诉我们！

栈跟踪

run: Enter any number to be squared 
25 (which is what i type in for example) 
Exception found in Client: java.util.NoSuchElementException 
Build Successful (total time: 31 seconds)

为什么我在这个Java客户端/服务器设置中得到NoSuchElementException？
