WRITING METHODS

Write a class MyMethods containing the following $2$ methods:

a method named volume$()$ that accepts $3$ integer parameters named width, length, and

height. The method returns the volume of the rectangular box it represents.

For example, if parameter values are $2,3,4,$ the method returns $24$

a method named avgFaceValues$()$ that takes $2$ Die objects as parameters $($Use the Die

class developed in class$).$ The method returns the average face value of the two die

objects. For example, if the first parameter is a Die object with face value $3$ and

second parameter a Die object with face value $4,$ the method should return $3\mathrm{.}5.$

Write an application, TestMethods, that tests$($invokes$)$ the methods in problem $1.$ The

program should instantiate an instance $($object$)$ of the class MyMethods and invoke the

methods with made up parameter data. The application should have at least one invocation of

each method.

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 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

a getter for each instance data

a setter for each instance data

an equals$()$ method that 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

public class Point

private int $x,y$;

public Point $($int newX, int newY

$x=$ new ;

$y=$ new $Y$

$\}$

public String tostring$()\{$

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

$\}$

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

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

other.y$,2))$;

$\}$

$\}$

Write an application CircleTest that first creates two Points objects, point$1$ with random

coordinates from $1$ to $25,$ 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.
