Yes there is. It's like inviting a guest multiple times for the same function. Waste of time and resources.

JVM will internally load the class only once no matter how many times you import the same class.

Only once complied and executed.

I does not make any difference to the compiled class (byte code) file if you import a package multiple times in a Java program. Java compiler just ignore it. Only it is an overhead to the compiler to detect it and remove it from the final compiled (byte code) file or .class file.

So yes it will take memory. But then we need not to worry about if we can use good editor/software like eclipse for Java programming which automatically removes the unused packages which will consume more memory

No effect if you import multiple packages because import package means you are only providing path.
