Setting icon on your java application ( in Jframe ) in Netbeans

If you are building an application in netbeans  , you may be stuck with icon . here am telling two different ways to set your application icon
first
************************
here you may create jframe class from right clicking on your package folder->new->jframe form.
 so name of your main jframe will be hidden from you.In such a situation
step1
copy png  image into your package folder containing same class
name to kk.pg(whatever you may like)
 step2
copy this code

this.setIconImage(new ImageIcon(getClass().getResource("/JavaApplication6/kk.png")).getImage());

or you can split into three lines ,( i put these lines to understand the working principle... :-) )

//         URL iconURL = getClass().getResource("/JavaApplication1/kk.png");
//         ImageIcon icon = new ImageIcon(iconURL);
//        this.setIconImage(icon.getImage());

here "this" means your java class
 kk.png is located in your package folder

"JavaApplication6" is your package folder

second
****************
the second way you may use to create jframe manually
for example

 JFrame frame1=new JFrame();
frame1.setIconImage(new ImageIcon(getClass().getResource("/JavaApplication6/kk.png")).getImage());

for such situation you can directly put your jframe name . here i created named frame1
