Question

通过控制台测试输出的正确方法是什么。我正在托管服务器和客户端来测试Collatz猜想输出，并且不希望计算机浪费时间重复先前解决的方程式。

目前，控制台输出一组如下

1,0 
2,1 
3,7 
4,2 
5,5 
6,8 
7,16 
8,3
(continuing on)

当它达到8,3时怎么能让它停止？

这是服务器的代码，希望不需要它。

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

public class Server {
    public static void main(String[] args) {
        new Server();
    }

    public Server() {
        try {
            ServerSocket sSocket = new ServerSocket(5000);
            System.out.println("Server started at: " + new Date());
            while(true) {
                Socket socket = sSocket.accept();
                ClientThread cT = new ClientThread(socket);
                new Thread(cT).start();
            }
        } catch(IOException exception) {
            System.out.println("Error: " + exception);
        }
    }

    class ClientThread implements Runnable {
        Socket threadSocket;

        public ClientThread(Socket socket) {
            threadSocket = socket;
        }

        public void run() {
            try {
                PrintWriter output = new PrintWriter(threadSocket.getOutputStream(), true);
                BufferedReader input = new BufferedReader(new InputStreamReader(threadSocket.getInputStream()));
                output.println("You have connected at: " + new Date());
                while(true) {
                    String chatInput = input.readLine();
                    System.out.println(chatInput);
                }
            } catch(IOException exception) {
                System.out.println("Error: " + exception);
            }
        }
    }
}

这是客户的代码

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

public class Client
{
public static void main(String[] args)
{
    new Client();
}

public Client()
{
    Scanner scanner = new Scanner(System.in);
    try {
        Socket socket = new Socket("localhost",5000);
        PrintWriter output = new PrintWriter(socket.getOutputStream(), true);
        BufferedReader input = new BufferedReader(new InputStreamReader(socket.getInputStream()));
        String inputString = input.readLine();
        System.out.println(inputString);
        boolean  start =true;
        int startnumber = 1;
        while(true) {
            int k=0;
            int stepnumber = 0;
            BigInteger i = BigInteger.valueOf(startnumber);

            while(i.compareTo(BigInteger.ONE) > 0){
                if(i.testBit(0)){
                    stepnumber +=1;
                    i = i.multiply(BigInteger.valueOf(3));
                   i = i.add(BigInteger.ONE);
                    k++;
                }
                else {
                    stepnumber +=1;
                    i = i.divide(BigInteger.valueOf(2));
                    k++;
                }
            }
            startnumber+=1;
            int finalstartnumber = startnumber -1;

            output.println(finalstartnumber + ","+ stepnumber + " ");
        }
    } catch (IOException exception) {
        System.out.println("Error: " + exception);
    }
}
}
