Java

Question

Define a class named ShapeList
ShapeList must extend ArrayList<Shape>
ShapeList must have a method with signature: ShapeList largestShapes()
The largestShapes method must return a ShapeList that contains all Shapes with the largest area
ShapeList must have a method with signature: boolean hasDistinctAreas()
The hasDistinctAreas method returns true means that:
for all Shape A and Shape B in the ShapeList, if A and B have the same area, then A.equals(B) is true
in other words, it returns true if distinct shapes have distinct areas

My code is below. What wrong with this? Can someone help me
import java.util.ArrayList;

public class ShapeList extends ArrayList<Shape> {

public void largestShapes(){
int resultList[] = new int[this.size()];
int largestArea =0;
for (int i=0; i< this.size(); i++){
if (computeArea(this[i])) > largestArea){
largestArea = computeArea(this[i]);
}
return resultList[];
}
}

public boolean hasDistinctAreas(){

Answer 1

This sure isn't a question.
Please post it on your personal feed or as a Java lesson

Answer 2

Why did you even import ArrayList if it isn't in your code?
Plus, you could use ArrayList in line 1 of largestShapes()
