Question

Why is my constructor not applying the variables?:

import java.awt.geom.Point2D;

public class Waypoint extends Point2D.Double{

private double s;
private String street;

public Waypoint(double x, double y, double s, String street) {
    super(x,y);
    s=9;
    street="Street";
}
   }

What is missing here?

Answer 1

Change

import java.awt.geom.Point2D;

public class Waypoint extends Point2D.Double{

    private double s;
    private String street;

    public Waypoint(double x, double y, double s, String street) {
        super(x,y);
        s=9;
        street="Street";
    }

To

import java.awt.geom.Point2D;

public class Waypoint extends Point2D.Double{

    private double s;
    private String street;

    public Waypoint(double x, double y, double s, String street) {
        super(x,y);
        this.s = s;
        this.street = street;
    }

You are not using the values passed to the constructor.
