Using Java, write the following code for a program to convert Hexadecimal to Decimal. Write a class hex with: -a public static method parselnt that accepts one String parameter named hex, computes the decimal value, and returns the int computed -a private static method value that accepts one char parameter named hexChar, determines and returns its int value -a public static method isValid that accepts one String parameter named hex, computes and returns true if the parameter is a valid hexadecimal string and false otherwise. Then, write a second class HexProcessor that invokes isValid to verify that the user input represents a valid hexadecimal string before invoking parselnt to determine the equivalent decimal value.
