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.
Naveed says
You are using only textfield. so in every iteration of loop, same textfield is updating.

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.
