I heard that using multiple import statements in a program affects its runtime performance. Is this true? If so, why?

They won't affect the performance of the application in any way. But in some cases, this may cause conflicts between classes in the namespace. So it's advised to avoid or remove unused imports from the code to improve readability and to avoid class conflicts.
Startup and Module Importing Overhead. Starting a Python interpreter and importing Python modules is relatively slow if you care about milliseconds. If you need to start hundreds or thousands of Python processes as part of a workload, this overhead will amount to several seconds of overhead.
Import statement in Java is helpful to take a class or all classes visible for a program specified under a package, with the help of a single statement. It is pretty beneficial as the programmer do not require to write the entire class definition.
Automatically organise import statements whenever you saveGo to Window > Preferences > Java > Editor > Save Actions. Select Perform the selected actions on save (off by default). Ensure that Organize imports is selected (on by default).
Not at all. Imports are only used during compilation, the class files do not have them anymore.
