Are all method in java implictly virtual

If there are no compile time binding in java, do this mean all binding are done at runtime?

But as per OOPs concept for runtime binding, functions must have virtual keyword..ARE all methods implicitly virtual in java or is there any compile time binding exist in java

If there is any compile time binding, can you give me some specific situation, or links to further information

  1. Static (There is no meaning of binding here as static does not belongs to object)

  2. final (this is not a valid point as it can be achived in another way)

Answer Source

All non-static, non-final and non-private methods are virtual by default in Java. However JVM is clever enough to find classes having only one implementation of given method and turn it into static binding.

This way you don't have to remember about virtual keyword (ever experienced memory leak due to missing virtual on destructor in C++?) while the performance is not impacted that much.
