Move All Zeroes to End of Array – Java Code

Write a java program to move all zeroes to end of array. In this tutorial, We are going to discuss another interesting problem which generally asked in an technical interviews.

Given an array of random integers move all zeroes of a given array to then end of an array. The order of all other elements of an array should be same.

For example, if a given array is {1, 2, 0, 4, 0, 5, 3, 8}, than the output should be {1, 2, 4, 5, 3, 8, 0, 0}.

Algorithm Move All Zeroes to End of Array

i) Traverse an array from left to right.

ii) While traversing an array maintain the count of non-zero elements in an array.

iii) For non-zero element, put the array element in arr[count] and increment the count.

iv) After complete traversal, non-zero element is already moved forward. Now, we can run a loop to put all zeros at the end of an array.
