POJava - how to add a png file to JPanel
text
Body
copied!<p>This Friday I need to hand in my Java project – I've only been programming for about two weeks now – and I really want to add a PNG file to my JPanel. Below you find my code, the name of the image is <strong>java.png</strong>, I put it in the same folder as my src files. I just can't find a good tutorial on how to do this. Please help me!<br> <em>Note:</em> the image should be inserted in the <code>booOpAfbeam</code> structure almost at the bottom of the code, and also sorry for this unorganized message, I have no clue how to post my code decently.</p> <pre><code> import java.awt.Color;
