Java – String charAt() Method example

The method charAt(int index) returns the character at the specified index. The index value should lie between 0 and length()-1. For e.g. s.charAt(0) would return the first character of the string “s”. It throws IndexOutOfBoundsException if the index is less than zero or greater than equal to the length of the string (index<0|| index>=length()).

Example:

In this example we are fetching few characters of the input string using charAt() method.

public class CharAtExample {
    public static void main(String args[]) {
        String str = "Welcome to string handling tutorial";
	char ch1 = str.charAt(0);
	char ch2 = str.charAt(5);
	char ch3 = str.charAt(11);
	char ch4 = str.charAt(20);
	System.out.println("Character at 0 index is: "+ch1);
	System.out.println("Character at 5th index is: "+ch2);
	System.out.println("Character at 11th index is: "+ch3);
	System.out.println("Character at 20th index is: "+ch4);
    }
}

Output:

Character at 0 index is: W
Character at 5th index is: m
Character at 11th index is: s
Character at 20th index is: n
