This is the code in java

Difference(int[] elements){
    this.elements = elements;

}

public void  computeDifference(){
   int smallest = 101;
   int largest = 0;

    for(int i = 0; i < elements.length; i++){
        if(elements[i] > largest){
            largest = elements[i];
        }
        if(elements[i] < smallest){
            smallest = elements[i];
        }
    }
    maximumDifference = largest - smallest;
