I can't figure out what went wrong ! I'm trying to run a simple sockets comunication. I'm using Eclipse Mars 2 and by the way, it cashes and quits in debug mode and when I try to run Junit tests ! I don't know why !

I get the error message above on the server, and a java.util.NoSuchElementException on the client ! precisely when I try to get the result from the server ( temp = scanner2.nextInt(); in Client.java )
Server class
package main;
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) throws IOException {
ServerSocket serverSocket = new ServerSocket(1234);
System.out.println("Waiting for the client...");
Socket socket = serverSocket.accept();
System.out.println("Client connected");
Scanner scanner = new Scanner(socket.getInputStream());
int number = scanner.nextInt();
int temp = number * 2;
PrintStream printStream = new PrintStream(socket.getOutputStream());
printStream.println(temp);
}
}
Client class
package main;
import java.io.IOException;
import java.io.PrintStream;
import java.net.Socket;
import java.net.UnknownHostException;
import java.util.Scanner;
public class Client {
public static void main(String[] args) throws UnknownHostException, IOException {
int number, temp = 0;
Scanner scanner = new Scanner(System.in); // to read input from user
Socket socket = new Socket("127.0.0.1", 1234);
Scanner scanner2 = new Scanner(socket.getInputStream()); // used to accept results from the server
System.out.println("Enter any number");
number = scanner.nextInt();
PrintStream printStream = new PrintStream(socket.getOutputStream());
printStream.println(number); // send the number to the server
temp = scanner2.nextInt();
System.out.println(temp);
}
}
