Icon in JButton

Question

I am trying to add in an icon to my JButton and so far nothing has worked. I have pasted below my code for the button and also the location of where the image is stored.

  public static DRTextCode BUTTON_COLLAPSE_NESTED() {
    DRTextCode tc = new DRTextCode ("BUTTON_COLLAPSE_NESTED",         "Collapse");
    return tc;
}


    btn = new JButton(BUTTON_COLLAPSE_NESTED().toString());
    btn.setActionCommand(BUTTON_COLLAPSE_NESTED().toString());
    btn.addActionListener(btnListener);
    btnPnl.add(btn);
    _collapseBtn = btn;

This below is the images location

"mz/images/svg/folder_collapse.svg"

I am not sure how to add this in

Answer 1

try to use .png icons because they are more common and easy to find them free,
you can find free flat icons here .

• first create a folder in this path src/resources

• put your icons that path and use them in this way

   JButton button = new JButton(); try { Image img = ImageIO.read(new File("src//resources//icon.png")); button.setIcon(new ImageIcon(img)); } catch (IOException ex) { }
