What does the charAt() method do in Java?

Hello Pratik, really nice question.

charAt() is a method in Java that lets you grab a single character from a string. You just give it the position you want, and it hands you back the character at that spot.

Java starts counting from zero, so:

• the first character is at index 0

• the second is at index 1

• and so on

For example:

String text = "Hello";
char c = text.charAt(1); // 'e'

If you try an index that doesn’t exist, Java throws an error because the string doesn't go that far.

You’ll use charAt() a lot when you loop through a string and check each character, like when counting vowels.
