Assignment Tasks:

Task $1$: Done

Task $2$: Method Overloading for Conditional Sums

Overload the calculate method to add a boolean parameter

onlyPositives. When onlyPositives is true, the method should return the

sum of only the positive numbers. When false, it should return the sum of

all numbers, mirroring the functionality of the original calculate method.

Task $3$: Method Overloading for Average Calculation

Further overload the calculate method to calculate the average instead of

the sum. This version should take an additional String parameter that

specifies the operation $("$sum$"$ or "average"$).$ Depending on the

operation specified, return either the sum or the average of the positive

numbers only.
