If I just need a simple function, I use it. If I need run-time polymorphism, I can use it. If I need duck-typing I can do it (in Python).

Those first two you can do in (modern) Java. The third is a mess to be avoided at all costs. Interfaces and lambdas will cover most reasonable use cases for polymorphism.
