i have now modified the above attached code somehow...........reduced the code to about 323 from 1000......
but still the code is running slowly...........according to me i think the problem is with the choice item allocation...........can anyone tell me how to solve this problem and make this code to run more faster than before...............

Please post the code on the forum.

pretty sure packing it in a jar file would increase running speed :)
all fun aside, as NormR1 mentioned, show your code.
we can't just go around and unzip-install-compile and run the entire project for everyone who posts a question about their code.
their are several reasons why your code might be slow: a thread temporarily blocking the execution of your program, or, an input file with a few thousand lines to process, or just one with ten to process ... there's a lot of possibilities out there.

Changing from Choice (AWT component) to JComboBox (Swing component) cuts the time in half roughly.
Using JTextfield makes it nearly instant and I can't see any benefit at all to using the combo boxes to choose a number 1-100.
Seems like a JTable would be a preferable UI choice.
NormR1 563 Posting Sage Team Colleague
If you're curious where the time is spent, add some printlns to show the current time at different points in the code.
System.out.println("end loop1 " + System.currentTimeMillis());
Also try using the -Xprof option to print out profiling stats.

I run the program in netbeans and it run fast because it does nothing. Maybe something is wrong with your computer or you're using netbeans in a wrong way.
