java - Scanner.nextInt 给出 InputMismatchException : For input string: "222234411110000"

Question

在我的程序中，我需要在两个奇数之间插入-，在偶数之间插入*并忽略如果有 0。例如:

Input = 99946   Output = 9-9-94*6
Input = 56647304    Output = 56*6*47-304

方法 getDigits() 将输入的 number 的数字放入数组单元格中。方法 insertDashesAsteriks() 返回正确连接的 String。

但是当我用下面的例子运行我的程序时:

Please enter the numbers so they could be rearranged:
222234411110000

Exception in thread "main" java.util.InputMismatchException: For input string: "222234411110000"
    at java.util.Scanner.nextInt(Unknown Source)
    at java.util.Scanner.nextInt(Unknown Source)
    at DashInsert2.main(DashInsert2.java:9)

然后我得到 InputMismatchException。为什么我会收到错误消息？

import java.util.Scanner;

public class DashInsert2 {

    public static void main(String[] args)
    {
        Scanner kbd = new Scanner(System.in);
        System.out.println("Please enter the numbers so they could be rearranged: ");
        int nums = kbd.nextInt();

        int[] numArray = getDigits(nums);
        System.out.println("The array representation of the numbers is \n");
        System.out.println();

        String result = insertDashesAsteriks(numArray);
        System.out.println("The result is " + result);

    }

    public static int[] getDigits(int numbers)
    {
        int length = Integer.toString(numbers).length();
        int[] temp = new int[length];

        for(int i = 0; i < length; i++)
        {
            temp[i] = numbers % 10;
            numbers = numbers / 10;
        }

        return temp;
    }

    public static String insertDashesAsteriks(int[] numArray)
    {
        String temp = "";
        for(int i = 1; i < numArray.length; i++)
        {
            if(numArray[i] % 2 == 0 && numArray[i-1] % 2 ==0)
            {
                temp = numArray[i-1] + "*" + numArray[i] + "*";
            }
            else if(numArray[i] == 0 || numArray[i-1] == 0)
            {
                temp = numArray[i-1] + "" + numArray[i] + "";
            }
            else if(numArray[i] % 2 != 0 && numArray[i-1] % 2 != 0)
            {
                temp = numArray[i-1] + "-" + numArray[i] + "-";
            }
        }

        return temp; 
    }
}

Answer 1

int 的最大值为 2,147,483,647

您输入了:222,234,411,110,000
