help me plz solve this problem?!?!!!

Project
This project consists of writing a Java application that sorts input data.
The program will perform the following steps:
Step 1. Read input from a screen – using GUI
Step 2. Sort the input. For example, if the input is a sequence (11,44,33,55,22), and descending order is selected then the sorted sequence will be (55,44,33,22,11). The user can choose either to sort in descending or ascending order.
For example, if the input sequence is
  4 2 9 3 5 6 7 8 10 11 1 12 14 13
then the screen will display the following information:
Data Structure: Array / Linked Chain
Sorting Algorithm: (whatever algorithm – taught in class)
Order : Ascending / Descending
Numbers Read In: 14

Input Sequence:
     4 2 9 3 5 6 7 8 10 11
     1 12 14 13

Sorted Sequence:
    14 13 12 11 10 9 8 7 6 5
     4 3 2 1

Sounds like your homework! I don't think anyone will want to do it for you and if they did you wouldn't learn much. So, lets have a look at what code you've written, or tell us how you think the program should work.

yup,my homework..i'm sorry.i can't think anymore..
this is what i'm doing...can you suggest some better program?

Research....

can u try to tell more abt ur qn?

It looks good to me!

You could use a single text field for the number input.

Alternatively you could use an array to hold the input text fields (which would save some typing) You also probably want to catch Numberformatexceptions and do something about them.

If you didn't want to write your own sort you could use Arrays sort http://java.sun.com/j2se/1.4.2/docs/api/java/util/Arrays.html#sort(int[])
