ΒΆ Fix the code
Copy the below code into a notepad (not an IDE so you don't get any help) and try to fix the code to get it to run and print the chess board.
Copy-paste the output into a comment at the top of your java file so that it looks something like this (doesn't have to be exact):
/* Expected output:
Ready To Play!
Hello ChessBoard!
Hello Board!
R P P R
B P P B
N P P N
Q P P Q
K P P K
N P P N
B P P B
R P P R
*/
/* Paste your output here:
*/
