Solution

public static void main(String[] args) {
      Scanner scnr = new Scanner(System.in);       
      /* Type your code here. */
      String fullName = scnr.nextLine();
      String[] nameParts = fullName.split(" ");
      char lastInitial = nameParts[nameParts.length - 1].charAt(0);

      System.out.print(lastInitial + "., " + nameParts[0]);

      if (nameParts.length == 3) {
			char middleInitial = nameParts[1].charAt(0);
      System.out.print(" " + middleInitial + ".");
      }

        System.out.println(); 
        
   }
}
