This is Java Programming:

Covert a Hexadecimal to decimal. Then write a program that can convert a binary to decimal (only for integer case).

There are two ways to do so:

Easy way: Directly use Java built-in method to do this. In this case, only couple lines of code. Hint: Study Integer class in Java.

Hard way: Write your own code to convert a binary to decimal from scratch. The input is a binary string. The program output is its corresponding decimal value. This way you need to design the algorithm.

You need to do both ways and test them correctly.
