Calling a base class constructor from derived class in Java

Question

I have a class as follows:

public class Polygon  extends Shape{

    private int noSides;
    private int lenghts[];

    public Polygon(int id,Point center,         


        

Answer 1

Your constructor should be

public Regularpolygon extends Polygon{

public Regularpolygon (int id,Point center,int noSides,int lengths[]){
super(id, center,noSides,lengths[]);

// YOUR CODE HERE

}

}
