Challenges

Remember the rules for this are

• Try to use only the information given up to this point in this book.
• Try not to give up until you've given it a solid attempt

Challenge 1.

Run javadoc on some of your code. Add the command for doing so to a Justfile. Make sure to include cleaning stale of output.

Challenge 2.

When you ran javadoc on your code you were almost certainly hit by a deluge of warning: no comment messages.

Fix these by documenting that code enough that javadoc no longer gives you warnings.

Challenge 3.

Read the documentation for java.util.StringJoiner.

If you can, alter one of your projects to use it.
