I have figured out how to change the icon for my program that I made in java, but now the default icon goes and nothing is there, is it because of the incorrect dimensions? I currently have a 16x16 logo, is anyone able to help me with what the dimensions need to do in order for it to display correctly?

Additional Note: The icon is a .png file if that helps in any way.

An app's Dock Tile Icon should be 1024 × 1024.

For more information about customising your Dock Tile, see the documentation:

  • It's still coming up blank - even when it is 1024 x 1024 - bearing in mind that this is Java. Commented Jan 10, 2015 at 12:08
  • @Connor Implementation is off-topic here. Try Stack Overflow, providing full details of what you are trying, with code.
