The charAt() method returns the character located at a String‘s specified index.
For example:
String str = "qwer";
System.out.println(str.charAt(2));It would output e because that’s what’s at index 2. (Once again, indices start with 0.)
Suppose we try return the character located at index 4, it would produce an error because index 4 is out of str‘s range.
