Q:

Java program to move all zero 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
```
