Question 1. Create a program that is similar to the previous one but has the following differences:

Instead of reading integer arguments, it reads floating-point arguments.

It displays the sum of the arguments, using exactly two digits to the right of the decimal point.

For example, suppose that you enter the following:

java FPAdder 1 1e2 3.0 4.754

The program would display 108.75. Depending on your locale, the decimal point might be a comma (,) instead of a period (.).

Question 2. Write a program that converts a hexadecimal digit into a decimal value.
