Help please I need my code to write 2D array to a text file also read from text. I manage to get it to store in the arraylist... so the characters are in the format
BBRRL
BBBBB
LLLBB
which are rows and columns. but when I try to keep it in the array list it prints the characters upside down so I use a trick which I think is wrong my printing j before i... it is suppose to be i before j. doing that it came out the way i wanted it... but when i save the file and look how it is stored in the text file i see different thing... even worst than what was in the arraylist.

here are my codes... and please can someone help me write a read method... to read from a text file into the 2d array. thanks.
