I'm trying to decide whether to change IDEs as I've read promising things about both NetBeans and IntelliJ, but I have two interrelated (perhaps dumb) questions:
Is there any difference in the final application produced by all 3 IDE's, assuming that all 3 use identical code (Java)? In other words, do IDE's package the final app in different ways, or add a watermark/signature file of sorts?
I often learn new programming techniques and tools by reading source code from smart developers. Is there any way to identify which IDE a certain app was built with by analyzing a Java app's source code? Such as a file containing "Built with NetBeans 8.0.2" or similar, somewhere?
