Write a Generic Class that adds two numbers of different data types $($Integer$,$ Double, Long$)$ and

test it using your own examples.

Problem $2$:

should compare the String data types taking into account the total number of characters; Integer

data types taking into account the total number of non$-$zero digits, and Double data types taking

into the significand $($the mantissa$)$ of the number.

Problem $4$:

Use Upper Bounded Wildcard to sum all elements of the list of elements, which the extend Number
