Ok Jeff,

Thank you very much for your reply.

Hi All,

I used the below code it's working fine and getting expected result.


I want to know can I handle this program better than this? because I am feeling using join() method is not appropriate, what if I have 1000 of threads?
One more question is it possible to suspend main thread till all other threads excecute?

Hi Jeff and Tony thanks for your reply.

Hi Pradeep,

It took me around 4 months of preparation. Actually I am working in software company along with 8 hours of work daily I did it(present am not working on java I want to move to java development so I did it). So now you can estimate your time dude. If you want to succeed you need to write lot of small programs for your understanding purpose. Take certification exam as a point of learning not just for certificate.

All the best

Thanks

Hi,

Can we directly go exam center and write the exam before taking voucher?Is there any possibility for writing exam like that? I heard just before exam itself we can take voucher and we can write the exam. If we need to take voucher before exam means how many days before we need to take and schedule the exam?

Please help me.
