Comments

File Count.java contains a Java program that counts from 1 to 5 in English, French, and Spanish. Save this file to your directory and compile and run it to see what it does. This exercise is primarily about Java comments. There are two types: first, a "//" means everything including and after the // is treated as a comment by the compiler. Second, a "/*" pairs with the next subsequent "*/" (sort of like parentheses) and everything including and between that pair is treated as a comment. This supports multi-line comments.

You will be submitting to the dropbox for this lab a modified copy of Count.java. As well, your lab document should contain your answers to the starred questions below.

Okay, with Count.java working, modify the code as follows:

1. Use // style comments to add a comment header at the top of the file that includes the name of the program, your name, and a brief description of what the program does, neatly formatted. Include a delimiter line (e.g., all stars) at the beginning and end of the header.

2. Add a comment before each println that indicates what language the next line is in. Experiment with leaving a blank line before each of these comment lines (in the program itself, not the output). Is the program easier to read with or without these blank lines?

3. *Remove one of the slashes from one of your comment lines and recompile the program, so one of the comments starts with a single /. What error do you get? Record the error message in your lab document. Replace the slash in Count.java

4. *Try putting a comment within a comment, so that a // appears after the initial // on a comment line. Does this cause problems?
