setIcon()

method in JButton class. The setIcon method takes an ImageIcon object as an argument. I will show you a sample java code in which the icon of  button is set. First of all,  you have to copy the icon image (jpg, bmp, png or gif image) to the src folder in the project directory. You may also place it in some folder inside the src folder. If you are using netbeans IDE, you can simply drag and drop the image file into the desired folder in the projects pane. After copying the icon image to src folder (or any subfolder in it), use the following code to set it as the button's icon.

playbtn.setIcon(new ImageIcon(getClass().getResource("/manhaj/images/play.png")));
