Question

i have class point:

public class Point
{
    private double _x;
    private double _y;

}

also i have getX(), getY() methods.
i need to define 2 methods:

1. public boolean isAbove(Point other)
2. public boolean isUnder(Point other)

So this is what I have come up with:

public boolean isAbove(Point other)
{
    if (this._y <= other._y)
    {
        return false;
    }
    else
    {
        return true;
    }
}

public boolean isUnder(Point other)
{   

}

I have tried several things on isUnder and get different results. What is the correct way to write those 2 methods ?

** important **

I have to use isAbove() method on isUnder() !!

Answer 1

isUnder can be implemented like this

public boolean isUnder(Point other)
{   
     return (this._y != other.getY()) && !isAbove(other);
}

and isAbove can be

public boolean isUnder(Point other)
    {   
         return (this._y > other.getY());
    }
