What do you understand by Synchronization Synchronization is a process of controlling the access of shared resources by the multiple threads in such a manner that only one thread can access one resource at a time. In non synchronized multithreaded application, it is possible for one thread to modify a shared object while another thread is in the process of using or updating the object’s value. Synchronization prevents such type of data corruption.
What is Polymorphism Polymorphism means any forms. In OOPS, it refers to the capability of objects to react differently to the same method. Polymorphism can be implemented in the Java language in the form of multiple methods having the same name. Java code uses a late-binding technique to support polymorphism; the method to be invoked is decided at runtime.
