How to you use the charAt method in the String class? (Java programming)?

Question

I tried looking at the API but it was still confusing.

Answer 1

String.charAt() takes an int as its only parameter, and returns a char. You call the charAt() method on a String to get the character at a certain position in the String. But, the first character is at position 0, the second character is at position 1, and so forth.

So, if you have:

String str = "abcdef";
System.out.print(str.charAt(1));

The program will print "1", because that's the second character in the String (remember, we're counting up from zeo).

If the position you give it is negative, or it's bigger than the number of characters in the String minus 1, charAt() throws an IndexOutOfBoundsException.
