Java / Jframe Help please...

Greetings, can someone help my with this practice? i have exam today and and I need to have this very clear....
Develop an application in java using Jframe that does the following:

1. Read 10 proper names.
2. Capitalize the proper names that have a letter "T".
3. Sort them alphabetically.
4. Names that end with "N" print them in lowercase.
5. Those names with more than 10 characters should not be stored.

That's all ... I appreciate too much who wants to help me....
