Free$-$Response Practice: Point$3$D Class

Consider the following class:

public class Point

$\{$

private int $x$;

private int $Y$;

public Point$($int newX, int newY$)$

$\{$

$x=$ new ;

$y=$ new ;

$\}$

public int getX$()$

$\{$ return $x$; $\}$

public int gety$()$

$\{$ return $y$; $\}$

$\}$

Write the class Point $3$D that extends this class to represent a three$-$dimensional point with $x,y,$ and $z$ coordinates. Be sure to use appropriate inheritance. Do not duplicate code.

You will need to write:

A constructor that takes three int values representing the $x,y,$ and $z$ coordinates

Appropriate mutator and accessor methods $($setters and getters$)$
