Now I am completely new to Java. I have just been introduced to it a little over a week ago and this is what I came up with:

```
import java.io.*;

public class A1Chuah {

    public static void main(String[] args) throws IOException {

        BufferedReader in = new BufferedReader (new InputStreamReader (System.in));

        //Prints instructions for user to enter first name.
        System.out.println("Enter first name: ");
        //Obtains user input for first name.
        String first = in.readLine ();
        //Prints instructions for user to enter last name.
        System.out.print ("Enter last name: ");
        //Obtains user input for last name.
        String last = in.readLine();
        //Prints instructions for user to enter birth year.
        System.out.print ("Enter your birth year: ");
        //Obtains user input for birth year.
        String year = in.readLine ();
        //Converts String year to int useryr
        int useryr = Integer.parseInt(year);
        //Sets int oriyr to value of 2012
        int oriyr = 2012;
        //Sets int outyr as oriyr - useryr
        int outyr = oriyr - useryr;
        //Prints out information.
        System.out.println("Hi" + " " + " " + last + "," + " " + "you will be" +  " " + outyr + " " + "by the end of this year");

```

I've managed to complete Bonus 1 and 3 but can't seem to figure out Bonus 2. Please help!
P.S. He said that I can get help as long as I don't try to pass it off as my own idea.
