Java Questions :Color Code

Write a program to read a string and validate whether the given string is a valid color code based on the following rules:

- Must start with "#" symbol

- Must contain six characters after #

- It may contain alphabets from A-F or digits from 0-9

Include a class UserMainCode with a static method validateColorCode which accepts a string. The return type (integer) should return 1 if the color is as per the rules else return -1.
