Please write simple java code & explain. WRITING CLASSES

Given the class Point below, define a class Circle that represents a circle with a given center and radius. The Circle class should have an attribute named center as well as an integer attribute named radius. The center is a Point object, defined by the class Point. The class should also have these members:

the constructor of the class, which should take parameters to initialize all attributes

getters for each instance data

setters for each instance data

an equals$()$ method that compares two circle objects for equality. The method returns true if two circles have same radii and false otherwise

a circumference$()$ method that returns the circumference of the circle

a toString$()$ method that returns the summary of a Circle object, e$.$g$.$

"Circle with radius $5,$ center x:$0,$y:$0"$

public class Point$\{$

private int x$,$ y;

public Point$($int newX, int newY$\{$

x $=$ newX;

y $=$ newY;

$\}$

public String toString$()\{$

return $"$x:$"+$x$+","+"$y:$"+$y;

$\}$

public double distance$($Point other$)\{$

return Math.sqrt$($Math$.$pow$($x$-$other.x$,2)+$Math.pow$($y$-$other.y$,2))$;

$\}$

$\}$

Write an application CircleTest that first creates two Points objects, F point$1$ with random coordinates from $1$ to $20,$ inclusive, and point$2$ with coordinates $0,0.$ The program will then instantiate two circles with the following radius$/$center requirements:

Radius entered from the keyboard and point$1$ as the center

Radius $5$ and point$2$ as the center

The program prints to the screen:

the summary of each circle

one of these two values:

the distance between their centers if the two circles are $$equal$$ OR

the average circumference, otherwise.

For full credit, you MUST use the circle objects and their instance methods when producing the two values to display.
