Question

Write a program for the following.

Create an array ZR[] of type int and size 10 and fill it with variables. Create another array NZR[ ] that contains only the non zero elements of array ZR[ ].

For example:

Input	ZR[ ]	100	405	84	0	25	0	0	45	0	0
Output	NZR[ ]	100	405	84	25	45

import java.util.Scanner;
public class FilterZeros 
{
    public static void main(String[] args) 
    {
        Scanner sc = new Scanner(System.in);        
        int ZR[] = new int[10];        
        System.out.println("Enter 10 integers for array ZR:");
        int nonZeroCount = 0;        
        for (int j = 0; j < ZR.length; j++) 
        {
            ZR[j] = sc.nextInt();
            if (ZR[j] != 0)
            {
                nonZeroCount++;
            }
        }        
        int NZR[] = new int[nonZeroCount];
        int nzIndex = 0;
        for (int j = 0; j < ZR.length; j++) 
        {
            if (ZR[j] != 0) {
                NZR[nzIndex] = ZR[j];
                nzIndex++;
            }
        }        
        System.out.print("NZR[ ]\t");
        for (int j = 0; j < NZR.length; j++) 
        {
            System.out.print(NZR[j] + "\t");
        }        
        sc.close();
