> How would I read each of the letters in a string?> Would I use a Scanner? What command?It is very easy to do. Look at the String class API. You will find your answer there.

You can access the letters in a String using method charAt. Check the API.

In Java versions >= 5, you can also use the extended for loop:

String s = ...

for(char ch : s.toCharArray()) {

}

Here is a really bad way to do it:

String word= "this is a test";

String firstLetter = (String[])(new ArrayList(new ArrayList(Arrays.asList(word.split(""))).subList(1,word.split("").length))).toArray(new String[]{})[0];

i think that should work

me too.. i made a small mistake:

String word= "this is a test";

String firstLetter = ((String[])(new ArrayList<String>(new ArrayList<String>(Arrays.asList(word.split(""))).subList(1,word.split("").length))).toArray(new String[]{}))[0];

System.out.println("first letter: "+firstLetter);

works like a charm! gets the first letter every time
