icon Turn in HW6 here. Homework 6 (Anagrams)

Due Thu Feb 24, 11:30pm.
No submissions accepted after Sun Feb 27, 11:30pm.

Specification:
Required Files:
  • icon LetterInventory.class, a class to help you count, add, and subtract letters from words and phrases
  • icon LetterInventory.jar, JAR archive version for Eclipse
    • For those using Eclipse, you should include LetterInventory.jar in your project. To add the JAR file to your project, select your project, go to the Projects menu and select Properties, then Java Build Path, then Libraries, then click Add JARs. When you add LetterInventory.jar to the build path, it should work.
    • For those using jGRASP or another basic editor, just put LetterInventory.class in the same folder as your program.

      Sometimes this program produces a lot of output. If you run it in jGRASP, it will display just 500 lines of output. If you want to see more, go to the Build menu and select the Run in MSDOS Window option. Then when the window pops up, right-click on the title bar of the window, select Properties, and under the Layout tab you should be able to adjust the Screen Buffer Size Height to something higher (like 9999 lines).

"I need help with my homework!"

  • There is probably someone in the IPL today, or maybe Marty has office hours. If so, go see them.
  • Check the message board; your question may have been answered there.
  • Read the relevant chapters and sections of the textbook, or watch the textbook "online portal" videos if you have access to them.
  • Look at the in-class lecture examples.
  • Look at this week's section handout problems and their solutions.
  • Send us a message on AIM. (AIM is better for short questions; anything that involves looking at multiple lines of code is better done by email.)
  • Start early! We get swamped the day assignments are due.
  • Don't panic. You have late days, and even if you run out, it is only -1 point for each day late.
