As and pointed out, the solution is to replace the JLabel's icon when the input handler detects the word "change". Key practical points that are missing from the short answers here: validate the typed text (trim and use a case-insensitive comparison such as equalsIgnoreCase("change")), and perform any image loading off the Swing event thread so the UI does not hang.

Load images as resources when possible (Class.getResource) so your code works from a jar as well as the IDE. For robust loading and better control (and to detect load failures), use ImageIO to read into a BufferedImage and then construct an Icon from that. Do the I/O on a background thread or with SwingWorker, then update the label on the EDT — see the Swing concurrency guidelines for details (Swing concurrency tutorial).

If the label size is fixed, scale images to fit before creating the icon; high-quality scaling using Graphics2D with rendering hints gives much better results than naive scaling methods. Cache frequently used icons in a map keyed by resource name so you do not reload or allocate new image objects on every input event.

Troubleshooting checklist: confirm the resource path and case sensitivity (Linux), provide a simple fallback icon when loading fails, avoid doing file I/O on the EDT, and call repaint/revalidate only if the UI does not refresh automatically. For image-loading details consult the ImageIO docs (ImageIO class).

By caling JLabel.setIcon() in whatever event you're using to process input.
