Static Modifiers are used to create class variable and class methods which can be accessed without instance of a class. Lets study how it works with variables and member functions.

Transient modifier :
When an instance variable is declared as transient, then its value doesn't persist when an object is serialized
When an instance variable is declared as transient, then its value doesn't persist when an object is serialized
Synchronized modifier :
When a method is synchronized it can be accessed by only one thread at a time. We will discuss it in detail in Thread.
