Hello, for an assignment I have to make a program in Java that converts Hexadecimal values to decimal, Binary values to decimal and also convert from Binary To Hexadecimal. the sample output is at the end.

This assignment is designed to get you to use loops in conjunction with the standard Java String class, the Java char type, and some arithmetic. Your program will take a hexadecimal or binary number as an input, and then print out its decimal value.

Your program must have a looping menu that prompts the user to choose between hex to decimal decoding, binary to decimal decoding, or binary to hex. Binary to hex is extra credit and is not required to be implemented.

Your program must use methods. The following method signatures must be matched, and implemented and used properly. They must not print anything out.

public static long hexStringDecode(String hex) //Decode whole hex string

public static short hexCharDecode(char hexChar) //Decode single character

public static long binaryStringDecode(String bin) //Decode binary string

public static String binaryToHex(String bin) //Optional

Sample Output:

Choose an option:

1. Decode a hex string.

2. Decode a binary string.

3. Convert binary to hex.

4. Quit.
