Inheritance program help

I have to write is program and I have no idea where to start with it. I'm not that good at java which is why i'm seeking help.

Write a Java program to simulate the operation of the four basic gates (AND, OR, NAND, NOR), USING the principles of INHERITANCE.
a. The Gates SuperClass has 2-Inputs and 1-Output.
b. The three individual SubClasses inherit the number of Inputs [a, b] and Output [c] from the SuperClass (Gates).
c. The four SubClass gates have their own specific and independent functions:

AND: a && b OR: a || b NAND: !( a && b) NOR: !(a || b )

could anyone please give me some code or basic directions on how I should start this it would be greatly appreciated

1)Write a Java program to simulate the operation of:
A)AND: a && b
B)OR: a || b
C)NAND: !( a && b)
D)NOR: !(a || b )
2)Using:
A)the principles of INHERITANCE
B)The Gates SuperClass has 2-Inputs and 1-Output.
C)The three individual SubClasses inherit the number of Inputs [a, b] and Output [c] from the SuperClass (Gates).
D)The four SubClass gates have their own specific and independent functions:

Before you begin
Define INHERITANCE in Java.
Turn the instructions into pseudo-code

my main confusion with the assignment is what the purpose of this is and what the outcome should look like. From what I understand I'm creating a Superclass called Gates and AND OR NAND NOR will all be subclasses and that I should extend them using keyword.

Instructors get a pay-raise every time someone asks that question on a forum. It is like a bonus.

What did the instructions say the output should look like? ... Exactly like that.

Sounds like a plan. Does this plan solve the problem while following all of the rules?
