sorry if this is a dumb thing for me to ask but how do I put the files contents into an array. say the file contains this "1, 5, 3, 8" how could I make that into an array like this "int chunk[] = 1, 5, 3, 8;" then I need to return the array

i've been trying to figure this out forever because you said the .txt file needs to be in the same directory, but in your vid i didn't see your main.java in the same directory as your deposits.txt. deposits.txt was in the directory before main.java. why is that?
