使用扫描程序无限扫描JSONObject程序时发生Java错误

我在编写这个程序时遇到这个错误，我只是想通过扫描器将json对象传递给JSONobject，然后打印json对象

但是扫描仪是无限循环的

package com.readvalues.main;

import java.util.Scanner;
import net.sf.json.JSONObject;

public class ReadValues 
{
    public static void main(String[] args)
    {
        String x="";
        try 
        {   
            System.out.println("Enter the data");
            Scanner scanner = new Scanner(System.in);
            while(scanner.hasNext())
            {
                x = x + scanner.next();
            }

            JSONObject jsonObject = JSONObject.fromObject(x);
            System.out.println(jsonObject);
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }
    }
}

我已经尝试了所有方法，扫描仪正在等待输入。。。 scanner.nextLine会有所帮助。

使用scanner.nextLine时，它会等待整数值。您正在输入一个json字符串，这就是它抱怨的原因。您需要将其更改为scanner.next，它需要一个字符串

同样，这样编写的循环永远不会结束。它将要求您永远从输入中读取字符串。您可能会考虑一些退出条件； 这是我在那里输入的程序的一个错误，我实际上使用了scanner.next循环永远不会结束，因为你还没有告诉它什么时候结束。一个常见的场景是，例如，检查某个字符串，当输入该字符串以结束循环时（这是我在那里键入的程序的错误），我实际上使用了scanner.next
