What is the function of default values in java?
Default values are available for any class or instance variable. If you do not specify a value for a class or instance variable the JVM will provide a default value that will ensure that the system does not end up with any unexpected errors because you used a variable that was not initialized. Ex: Public class Test { int I; } In the above class we have just declared an instance variable called 'I' but we haven't associated any value to it. The JVM automatically assigns 0 as the default value to this variable.

Static member variables of a class are variables that are local to the class within which they are declared. That is, each instance of the class (each object) shares the same common member variable.

Contrast with a non-static member variable where each instance of the class has its own independent variable, scoped to the object itself (not the class of object).
