Java program to move all zero at the end of the array

In this java program, we are implementing a logic in which all zeros (0) of given array will be moved at the end of the array.

Given an integer array with zeros (0’s) and we have to move all zeros at the end of the array using java program.

Example:

    Input array: 5, 1, 6, 0, 0, 3, 9, 0, 6, 7, 8, 12, 10, 0, 2
    After moving 0 at the end 
    Output array: 5, 1, 6, 3, 9, 6, 7, 8, 12, 10, 2, 0, 0, 0, 0

Program to move zeros at the end of the array in java

public class MoveZeros
{
	 static void moveZeroElementToEnd(int[] arr)
	 {  
		 // declare and initialize.
		 int size = arr.length;  
	     int count = 0;  
	  
	     // access all array elements.
	     for (int i = 0; i < size; i++)
	     {  
	    	 if (arr[i] != 0)
	    	 {  
	             arr[count++] = arr[i];  
	         }  
	     }  
	  
	     while (count < size)  
	     arr[count++] = 0;  
	 }  
	  
	 public static void main(String[] args) 
	 {  
		 // take default elements in array.
	     int[] arr = {5, 1, 6, 0, 0, 3, 9, 0, 6, 7, 8, 12, 10, 0, 2};  
	     moveZeroElementToEnd(arr);   
	     
	     // print elements after moving 0's to end
	     System.out.print("Array after moving zeros to end : ");  
	  
	     for (int i = 0, size = arr.length; i < size; i++)  
	     System.out.print(arr[i] + " ");  
	 }  
}

Output

    Array after moving zeros to end : 5 1 6 3 9 6 7 8 12 10 2 0 0 0 0
