I have tried reading this every way I can think of and for the life of me I can't figure out why the if/else statement in the actionlistener will never evaluate the if statement to true. This program is meant to open a JFrame with 3 panels. 2 of them have 8 Random buttons with letters on them. When a button is clicked it is supposed to say if it's a vowel or a consonant. However my program always evaluates the button to a consonant. Where am I not seeing the logical flow of info in the program?
