A Java command line game where the user must guess a number from 1-20.

Requirements:

1. The game asks the user for their name, guess, and whether or not they would like to play again.
2. The game must generate a random number from 1-20.
3. The game has input validation using try catch blocks for the name (no empty string and no special characters).
4. The game has input validation using try catch blocks for the guesses (no empty string and must be a number from 1-20).
5. The game has input validation using try catch blocks for whether the user wants to play again (no empty string and only y/Y or n/N).
6. The game must reset if the user answers yes and ends if the user says no.
7. The game has a counter to keep track of how many valid guesses the user makes before winning.
8. If the user's guess is wrong, the program will tell the user whether their guess is too high or too low.
