Finding Duplicate Elements in an Array | Java Interview Programmes | Program 8

Explanation of the code:

The array a contains the elements for which we want to find duplicates.

The variable length is assigned the length of the array a.

The outer loop (for loop with variable i) iterates through each element of the array.

The inner loop (for loop with variable j) starts from the position after the current i and iterates through the rest of the array.

Inside the inner loop, the if statement checks if the element at position i is equal to the element at position j. If they are equal, it means a duplicate is found.

If a duplicate is found, the duplicate element (the value at position i) is printed.
