Beginner here when it comes to developing computer applications. Whenever I try to add an image to the application I am making, the GUI window does not show up. When the image is deleted, the GUI window loads fine with no errors. I think everything is fine when it comes to the path name for the image file in the code. Below is my code:
package myPack;
//import javax.swing.SwingUtilities;
import javax.swing.ImageIcon;
public class jFrameTest extends javax.swing.JFrame {
public jFrameTest() {
initComponents();
setIconImage(new ImageIcon(getClass().getResource("/src/main/java/myPack/fbla.png")).getImage());
}

jLabel2 = new javax.swing.JLabel();

gradeField = new javax.swing.JTextField();
setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

The error at line 20 of the code refers to this:

Please let me know if you have any suggestions.
