Is it Possible to change icon window exported application?

I made a simple software to display the data from the sensor using processing when I export the application it worked no problem. But the window icon is just a “plain black square”. Software that I made for Windows 64 bit. I saw some references on the internet that use the frame function, but that function in Processing v4 doesn’t exist. So can the icon be changed? I’m using the latest processing, Processing 4.0 beta 2
