What is the title of the software?

How many of (put name of software here) are in stock?

The program should then sort the items so that the records are in order by title or number of stock and display all of the records in alphabetical or numerical order. Decide on the menu options this program needs.

Examples of input could be:
LOTUS 123 54
WordPerfect 26
Microsoft Word 33
Microsoft Excel 11

Have Output similar to the following:

COMPUTERS R US Software Inventory
TITLE QUANTITY
LOTUS 123 54
Microsoft Excel 11
WordPerfect 26
WordPerfect 26

*****IMPORTANT: I use java 1.4.2 and not any newer. Please ensure that the program works with java 1.4.2. classes such as scanner dont work.Lifesaver will be rated if it works well. INCLUDE A SCREENSHOT please!
