  4. 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.

  27. 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.
