Thank you! Can you give me a hint on how I might, from that, then use the character read in in a series of if/else statements? My professor never taught us file IO.

You have to be more precise. What kind of tests do you need to do? And these tests are unrelated to I/O.
If the problem is to get a specific character at a given position, it was done with the chartAt() shown above.

More specifically, I need the program to do open the file, read each character in the file, and for each of the vowels it encounters generate a specific graphic. While I know how to write the for loop and if-else statements to get this to work, it's getting each character to be read that's my question. If the code above will do that, then wonderful.

Never mind, solved!

Thank you for all your help!
