Answer :

Instance variables are variables that are declared inside a class but outside of constructors, methods, or blocks.

What is Instance variables?

  • A variable declared in a class—i.e., a member variable—for which each instantiated object of the class has a separate copy, or instance, is referred to as an instance variable in class-based, object-oriented programming.
  • While a class variable and an instance variable are similar in nature, the latter are not static. Instance variables are variables that are declared inside a class but outside of constructors, methods, or blocks.
  • When an object is formed, instance variables are produced as well, and they are available to all of the class' constructors, methods, and blocks. A variable's instance may get access modifiers.
  • Despite certain similarities, an instance variable is not a class variable. The attribute belongs to a certain class (or class property, field, or data member).
  • A class may have both instance methods and class methods; the distinction between instance and class members is the same for methods (also known as "member functions").
  • For the duration of the ownership of the object, each instance variable remains in memory.
