CountDistinctElements

In various algorithms and software, often there's a need to find the distinct elements in an array. This class helps you do exactly that efficiently.

To use this class, just make a simple object of CountDistinctElement class with the integer array of your choice. Then just call countDistinct() method which returns you the number of distinct elements in your array from above.

public int countDistinct() {
	// returns number of distinct elements in your array
}

Example code, for understanding:

public static void main(String[] args){

	int[] arr = new int[]{1, 2, 3, 4, 2, 3,1,5};
          
        CountDistinctElements cd = new CountDistinctElements(arr);
        System.out.println(cd.countDistinct()); // returns 5 as that is the number of distinct elements
}
