Create a class named Board. The class has the following instance variables, constructors, and methods. • Private instance variables brand of type String, color of type String, width of type int, and height of type int. • A public empty no-arg constructor • A public constructor that has four parameters and sets the instance variables accordingly. Use the reference this in your implementation. • Public getter and setter methods for each of the instance variables color and width. Use the reference this in the setter methods. • A public static method that takes two parameters of type Board and returns a boolean value. The method returns true if the instance variables width and height of the first argument is equal are to the instance variable width and height of the second argument, respectively. The method's header is as follows: public static boolean equals (Board bl, Board b2) The method should also return true if b1 is equal to b2 (reference variable comparison). • A public method named display() that displays the instance variables of the invoking object in a format of your choice.

• A public empty no-arg constructor
A public constructor that has four parameters and sets the instance variables
accordingly. Use the reference this in your implementation.
• Public getter and setter methods for each of the instance variables color and
width. Use the reference this in the setter methods.
• A public static method that takes two parameters of type Board and returns a

height of the second argument, respectively. The method's header is as
follows:
public static boolean equals (Board bl, Board b2)
The method should also return true if b1 is equal to b2 (reference variable
comparison).
