Fully document your code with meaningful comments. Use a consistent and readable indentation scheme. You will be graded on both the correctness of your programs and the style in which they are written.

In-Lab Work

This is not a test! If you have any trouble at all with these programs, your AI will be happy to help you!

• Write a program that prompts the user for a sentence containing 4 words, and then generates the same sentence in broken pig-latin.

  We define broken pig-latin in the following way:

  Any word, whether it starts with a vowel or otherwise, is converted to pig-latin by taking out the first character, attaching it at the end of the word, and then adding the suffix 'ay' to it. Here's a sample run.

  Give me a 4 word sentence: My name is Joe.
  
  Piglatin sentence: yMay amenay siay oeJay.
  

  Do not worry about what happens if the user enters a sentence with more than 4 words. You may assume that she will always enter 4.

  You will need to make use of the substring method again in the String class. This method is described on page 68 of the text.

  Save your program as Brokenpig.java.

Lab Assignment

Please take care to use the exact filenames specified in the problems below.

1. Take the broken piglatin program that you created in the lab, and modify it so that the uppercase characters are handled somewhat properly. Don't worry about names. Simply make sure that the first word starts with an uppercase character, and no other characters in any other words are uppercased. So, the program should run in the follwoing way with the same input as in the above exercise:

   Give me a 4 word sentence: My name is Joe.
   
   Piglatin sentence: Ymay amenay siay oejay.
   

   Save your program as Smartpig.java.

2. Exercise P2.21, Page 84. Save your program in a file named Letters.java. Feel free to use the special characters like '\n', '\t' and so on.

3. Write a program that asks for the due date and time for the next quiz or assignment. Then it should output how many full hours you have before you need to submit the assignment. (So if you have two and a half hours left, you should generate two hours). A sample run may look like the following. You may design the actual input sequence or format, but make sure your prompt tells the user what to type:

   Please enter the name of assignment due (Lab/quiz): Lab3
   Please enter the date it is due:
   Month: 2
   Date: 10
   Hour (in 24 hour format): 23
   Minute:59
   
   You have about 168 hours to finish this assignment! Keep it up!
   

   Hint: remember that one hour has 3600 seconds. And remember integer division!

   Name this program Deadline.java

Submitting Your Lab Assignment

For this lab, you must submit the in-lab exercise during your normally scheduled lab session. By Wednesday, February 10 at midninght you should submit these three files:

• Smartpig.java
• Letters.java
• Deadline.java

Do not submit .prj or .class files. Only the three files named above should be submitted.

In order to submit files, click on the following link to send mail to:

with the following Subject:

and then Attach your program files to the e-mail message. You may attach all three files in the same message, but you don't have to. You can submit your programs in separate e-mails if you wish. Do not type anything in the body of the message! You must use the filenames specified in this assignment and you must attach the files to the mail message.
