将用户字符串整数输入存入整数数组java

Question

在此赋值中，我必须将整数字符串输入＆＃34; 1234＆＃34;存储到整数数组中，程序必须反向输出数组，总和和平均值。它必须继续提示用户输入字符串，除非他们输入＆＃34; end＆＃34;。

一切正常它只是程序打印出-14,4,3,2,1，-14，我不知道如何解决这个问题我也不知道输入while循环结束程序的值是什么。任何帮助将不胜感激

import java.util.*;

public class Assign1
{
public static void main(String[] args)
{
    int sum=0;
    String input;

    Scanner scan = new Scanner(System.in);

do{
    System.out.println("Enter in a string of integers: ");
    input = scan.nextLine();

    //makes the size of the array according to the length of the user input
    int[] intArr =  new int[input.length()];

    //loop to store integers in array
    for(int i=0; i<input.length(); i++)
    {
        intArr[i]= input.charAt(i)-'0';

    }

    //loop to calculate sum of elements in array
    for(int i : intArr)
    {
        sum=sum+i;
    }
    System.out.println("Sum of array elements is: " + sum);


    //calcluates the average of elements in array
    double average = sum/input.length();
    System.out.println("Average value of array elements is: " + average);


    printReversed(intArr);
  }
  while(input!=" ");

}
public static void printReversed(int[] values)
{

    //loop that prints out elements in reverse order
    for(int i= values.length-1; i>=0; i--)
    {
        System.out.println(values[i]);
    }



}
