Hi Friends

Could someone throw some light on what happens when you write additional import statements besides those that are being used in a java program ?
Does it slows down stuff or something ?

Thanks

No. Import statements are just an indication for the compiler where to look for classes necessary during compilation. After all classes have been found and the program has been compiled, the imports are just discarded.

In other words, imports have precisely zero effect on the generated bytecode, and therefore have zero effect at runtime.
 
I agree. Here's the link: http://aspose.com/file-tools
