In Java How To Find Finding Duplicates In Array?

In this tutorial, we will Learn In Java How To Find Finding Duplicates In an Array? We can do so using comparing each element of the array with each element of the array except the original elements. Using nested for loop with the help of if else conditional operations.


Array In Java And Its Elements

Array in java can store any non Null value in it and store them at a particular place that we call elements and each element have a location that we call an index number so that we can access the element directly with the complexity of constant and make it simple as compare to other data structures so let understand it in details.

Finding Duplicates In Array

We can find the duplicate array simply by applying two nested for loops so that we can compare each element with other elements of the array and that makes the complexity of this program quadratic that is O(n^2) and to implement the same in simple ways you can follow the code given below.


int[] arr = [1, 2, 3, 4, 2, 7, 8, 8, 3];   
System.println (" Duplicate elements in given array: ");  
// Searches for duplicate element  
for i in range(0, len(arr)):  
    for j in range(i+1, len(arr)):  
        if(arr[i] == arr[j]):  

            System.println( arr[j]);

Here in the above example we have an array arr with a number of elements as duplicates or we can say there are repeating so to remove them we applied nested for loop. And we have printed the array after removing duplicate values.
