Java: How to change icon of file programmatically?

H开发者_运维知识库ow to change icon of a file programmatically using Java? It shouldn't be for a jar application.

Well there is one way that I can think of and I know it has been done:

• Step 1: you change that file's extension
• Step 2: you change the operating system associated program to that new extension to the one of the previous extension
• Step 3: you change the system icon for that particular extension

One flaw though is that for some types of file (especially on osx) you will have this preview mechanism going... I think this would be a lot easier to accomplish on windows.
