Wrapper Classes Are Not Explained……….

Thank You so much…………….
Java TYPE CASTING also not explained
assalam-o-alaikum Sir!
i am beginner to JAVA
my question is, how to pass a loop variable value to textfield in JFrame.
e.g
for(int i=0;i<5;i++)
{
textfield.settext(Integer.toString(i));
try{ Thread.sleep(1000);}
catch(Exception obj){System.err.println("Exception occured");}
}
it only displays the last value of loop with terminates in textfield.
You are using only textfield. so in every iteration of loop, same textfield is updating.
You’ve written the wrong program dude.

Hello Chaitanya,
I am pretty sure that over a period of time you will upload more concepts and tutorials for different technologies, but at the same time I would suggest or better request you to add a frame where you or anybody can post different questions related to particular concept and a person can try writing a code for it. Like a list of programs or something similar to exercises given in Kathy Serra , which on solving can make person better understand the concepts and have hands on programming experience.
Seems like a great idea. I would definitely think about it.

Appreciate for your simple and straightforward explanation….!
But It would be very good, if you also post about Java Networking and and Crypthography.
