    Default Array help

    Hello, I'm new to java and I'm pretty bad at it. When I run my program it says array index out of bounds. I'm supposed to write a program that translates an English sentence to morse code with a driver and utility class. I have to read in a txt file that list the morse code translation like:
    A .-
    B -...

    I tried reading in the txt file and then calling on a method in my utility class to store them in an array

    			int r=0;
    			String q = file.nextLine(); 
    (I made the array [26][2])
    public void setM(String q, int r)
    		Char letter=c.charAt(0);
    Then later to translate the code I call on a method in my utility class where I bring in g as a string argument (g is the next letter in the string I'm string to translate)
    int w=0;
    I'm sorry if this looks choppy, I just don't want to get accused of cheating so I only listed the parts I thought might be the problem. I just need a hint, thank you.

    array index out of bounds.
    The index has gone past the end of the array.
    Remember: the values of array indexes range from 0 to the array length-1.
    An array with 2 slots has the two indexes: 0 & 1

    Please edit your post and wrap your code with code tags:
    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.
