Can you explain what your problem is?

What does the code do now?
What do you want to change about the way it executes?

Hello,I want to create a way when the game is over, the "Play Again" option appears. Where and how to put this in my code, this "while" function.

The first thing to do is break your code up into methods.
Trying to add a loop around that lot will make it even messier than it already is.

Here are a couple other observations. You have already shown here

alphabetArray[(int) Character.toUpperCase(check) - 65] = " ";

That you understand character arithmetic to help index into an array.

Yet in lines 210 thru 290 you have this brute force switch statement. With a little
thought, you might find a cleaner way to index those values. And you should
have a default case statement (just in case - no pun intended).

And, when you print out the hangman, why not just use an array to build the
hangman and add the body parts (ugh - sounds macabre) to the array as
appropriate. Then call a method to print out the hangman.
