Printing different colored squares to the screen based on characters read from a text file?

You have a .txt fie named List. This file contains the following (without quotes): "0, 1, 0, 0, 1". Your Java program should parse these in and print the corresponding colors for each character:

0 = blue

1 = red

Make sure the squares are a distance away from each other so they don't go ontop of each other. I understand how to create/open/write to a file but not how to put it to graphics as this is asking. :/
