In Java, Method-ize the Hex to Decimal Program we wrote (Program 4.2) rewriting the program to implement a method to handle the conversion of the hexadecimal string into a decimal value

Program Behavior: The main method should prompt the user for the needed input, then call a new method to calculate the decimal value of the hexadecimal value retrieved from the user. The new method should return the decimal to the main method which will then print the value or an error message.

The new Method should receive a String and return an integer. If an invalid hexadecimal value was entered by the user, the method should return a -1.
