How to set the picture in the label in java to automatically adapt as the label stretches, the code or method to adjust the size of the picture, etc...

In Java, you can use the setIconTextGap() method to set the gap between the picture and the text, so that the picture is automatically resized as the label is stretched. In addition, you can also use the setPreferredSize() method to set the recommended size of the label image, so that the ratio remains unchanged when the image is stretched.
