Consider the following class:

public class Point $\{$

private int x;

private int y;

public Point$($int xCoord, int yCoord$)$

$\{$

x $=$ xCoord;

y $=$ yCoord;

$\}$

public void move$($int dx$,$ int dy$)\{$

x $+=$ dx;

y $+=$ dy; $\}$

public String toString$()\{$

return x $+","+$ y; $\}$

$\}$

Identify the following:

a$.$ Fields

b$.$ Methods

c$.$ What is another method that you might want when creating a class about x$,$y points?
