Instructions from your teacher:

Warm up

Use Scanner and System.in to read data from the user, then System.out to print it back out.

Use Scanner.nextLine() and related .next*() methods.

Use String methods.

Field of stars

After doing the first N exercises, use the special characters \t and to output this flag-like set of stars. Don't use spaces or tabs in your println() calls, use "\t" instead.

* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *

After getting the stars to print, add another set of code to print with double quotes (") instead of asterisks (*).
