Please go through the Guide For New Members and BB Code List - Java Programming Forum - Learn Java Programming then edit your post accordingly.

How are you running that code? There's no entry point.

The method that adds content to Admission_2 isn't called from anywhere. Not that a constructor must have the same name as the class (and Java is case sensitive) and have no return type, not even void.

yes i know its a blank form ya it sounds stupid but shouldn't it run??

Thank you for editing your code/post. You code suffers from a "pseudo" constructor. Remember that constructors have no return type, not void, not anything. Also, constructor names should be spelled and capitalized *exactly* the same as the class name.

So, not:

Java Code:

public void admission_2() {

but rather:

Java Code:

public Admission_2() {

Also your main method should be static. Also the code would benefit from use of arrays. Also, you'll want to use nested JPanels with their own layouts to get a better GUI layout, avoid setting sizes of anything, and calling pack() on the JFrame before displaying it to tell the layout managers to do their thing.

**harshit shah** · 01-13-2013, 02:59 PM

hmmm yup my fault...

but how do you suggest i arrange it properly?
i want to give it a form-like look and feel...just the way see online registration forms...what do you suggest i should do?
thanks a lot..

Consider using a GridBagLayout for your JLabel/JTextField table of components and consider nesting JPanels, each using its own layout to create complex GUIs. You can find examples here:

**harshit shah** · 01-13-2013, 05:16 PM

hmm....thanks a lot,but still can you help me arrange the JLabels using gridlayout
i don't want a complex a program just basic...it will fetch me more marks than i require.

edit:

kk got it thanks by changing the panels grid layout.

SORRY i bumped this post can u tell me how to add a print button below my JFrame..to print the whole frame along with it contents..i would also like to add a local/online picture to the panel...any suggestions?

**harshit shah** · 01-14-2013, 03:41 PM

i am pretty new to this forum, and just read the rules...so pardon if i am breaking rules here...
but i want to add a print button to my current frame so that it prints the whole frame with it's contents.
also, i would like to add a picture(local/online) to the current frame as well.
