        //System.out.println(name.lastIndexOf(“n”));//Returns the last index of the specified character from the given string. (7 in this case)

        //System.out.println(name.equals(“AmanJain”));Returns true if the given string is equal to “AmanJain” false otherwise [Case sensitive]

        //System.out.println(name.equalsIgnoreCase(“amanjain”));//Returns true if two strings are equal, ignoring the case of characters.
