I am working on a project which will have 8 jFrames. Once I added an image into my 5th jFrame, the next button stopped working on the previous jFrame. If I remove the image it seems to work again. I put the image file into the packages file where all the java files are located. Code for the next button in 4th jFrame

    private void btnNextActionPerformed(java.awt.event.ActionEvent evt) {                                        
        culminating5 open =new culminating5();
        open.setVisible(true);
        dispose();

I'm using this similar code with everything else an it is working fine. Code shows no errors aswell.

Here's what the output shows when I press the next button from the 4th jFrame:

  • Your issue starts in `culminating5.initComponents` and would appear that what ever value your sending to `ImageIcon` is `null` – MadProgrammer Jul 14 '20 at 23:32
