Create a Class named Operation. Create four instance variables num$1,$ num$2,$ Sum for addition, and Difference for subtraction. Then, create methods for ComputeSum and ComputeDifference, create the set methods for num$1$ and num$2,$ and get methods for Sum and Difference. The operation accepts two integers.

Operation

num$1$: int

num$2$: int

sum: int

difference: int

ComputeSum$()$: void

ComputeDifference$()$: void

set method for num$1$ and num$2$

get method for sum and difference

optional:

displayResults$()$

$2.$ Create another class named $$OperationTest$.$ This class will read two integers. Define an object of type Operation. Compute and output the Sum and Difference using the method defined in the class $$Operation
