charAt() of String

charAt() of String class is a simple method to find out the character at a particular position in the String.

Structure of charAt() looks like

public char charAt(int index)
- Returns the character at a particular index in the String

Lets say for String "Zartab", if i need to find what is the character at index number

So now to get any character at location let say 4, we need to write the code as

String str="Zartab";

char c=str.charAt(4);

System.out.println(c);

c will return 'A'.

The whole will look like

class CharAtDemo 

{

public static void main(String[] args) 

{

String str="ZARTAB";

char c=str.charAt(4);

System.out.println(c);

}

}
