String to char in java- str.charat(index)

If you want to display or get any one character from a string, java provides a method .charAt(index) [this returns a character from the specified index], let’s see the implementation

index should be with in the string length range, else will get exception java.lang.StringIndexOutOfBoundsException

public static void main(String[] args) {
		String myStr = new String("Welcome");
                System.out.println("Character ay index 0 - " + myStr.charAt(0));
		System.out.println("Character at index 1 - " + myStr.charAt(1));
}

Output

Character ay index 0 - W
Character at index 1 - e

String “Welcome” is of length 7, so the index should be from 0 to 6.
