Code in Python

def computeDifference(self):
        self.maximumDifference = max(self.__elements) - min(self.__elements)

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;


}

Can someone explain to me while the following code only returns zeroes (JAVA):

public int computeDifference(){ Arrays.sort(elements); int len = elements.length-1;

    int maximumDifference = Math.abs(elements[0] - elements[len]);
    return maximumDifference;
}

C#

    public Difference(int[] elements)
    {
        this.elements = elements;
        this.maximumDifference = 0;
    }

    public int computeDifference()
    {
        Array.Sort(elements);
        
        //getting max and min values and getting the abs difference of them
        maximumDifference = Math.Abs(elements[0] - elements[elements.Length-1]);
        
        return maximumDifference;
    }

JAVA SOLUTION

class Difference { private int[] elements; public int maximumDifference;

// Add your code here
public Difference(int[] elements){
    this.elements = elements;
}

public void computeDifference(){        
    Arrays.sort(elements);

    int min = Arrays.stream(elements).min().getAsInt();
    int max = Arrays.stream(elements).max().getAsInt();
    maximumDifference = max - min;

}
