In my JFrame i have the default coffee icon. I want to remove it. But when i do setIconImage(null) it does't work. Can anyone tell me the solution as to how to completely remove the icon

Simple, Set the icon to null . It doesn't have an icon, so it removes it. That will work perfectly.
The efficient way of closing the JFrame is that we use the inbuilt method provided by the JFrame class i.e., using the JFrame. setDefaultCloseOperation(int) method. We use this method to change the behavior of the default JFrame which hides it instead of disposing of it when the user closes the window.
JFrame is a top-level container that provides a window on the screen. A frame is actually a base window on which other components rely, namely the menu bar, panels, labels, text fields, buttons, etc. Almost every other Swing application starts with the JFrame window.
It's always good to keep a copy of the Java source code around. The code for java.awt.Window (a superclass of JFrame) has the following code for setIconImage:
public void setIconImage(Image image)
{
ArrayList<Image> imageList = new ArrayList<Image>();
if (image != null)
{
imageList.add(image);
}
setIconImages(imageList);
}
You can see that passing in a null image is the same as doing nothing so you'll have to pass in an image to get rid of the coffee cup. As others have suggested using a 1 x 1 transparent icon is your best bet. Here is some code to create the icon:
Image icon = new BufferedImage(1, 1, BufferedImage.TYPE_INT_ARGB_PRE);
myFrame.setIconImage(icon);
