What are the different scopes for Java variables?
The scope of a Java variable is determined by the context in which the
variable is declared. Thus a java variable can have one of the three
scopes at any given point in time.
1. Instance : - These are typical object level variables, they are
initialized to default values at the time of creation of object, and
remain accessible as long as the object accessible.
2. Local : - These are the variables that are defined within a method.
They remain accessbile only during the course of method excecution.
When the method finishes execution, these variables fall out of scope.
3. Static: - These are the class level variables. They are initialized
when the class is loaded in JVM for the first time and remain there as
long as the class remains loaded. They are not tied to any particular
object instance.
