Working with Methods — Question 7

Scope of the variable determines in which parts of the program the variable is accessible. It is of the following types:

1. Local Variables — The variables declared inside a method or block are called local variables. The scope of local variables is limited to the method or the block they are declared in.
2. Parameter Variables — The variables used as arguments in the method prototype are called parameter variables. Their scope is limited to the method where they are being used.
3. Instance Variables (non-static variable) — The member variables that store the state of an object are known as instance variables.
4. Class Variables (static variable) — A variable declared in a class with the static modifier is called a class variable.
