Identity: An object identity is typically implemented via a unique ID. The value of the ID is not visible to the external user. However, it is used internally by the JVM to identify each object uniquely. For Example, Pen is an object. Its name is Reynolds; color is white, known as its state.
What is an instance variable?
A variable which is created inside the class but outside the method is known as an instance variable. Instance variable doesn't get memory at compile time. It gets memory at runtime when an object or instance is created. That is why it is known as an instance variable.

What is p1 and p2 in Java?
Here p1 and p2 are objects of Person class. Once the code line Person p1 = new Person (); executed, java constructors creates the object p1 in heap memory and assigns the default values of the instance variables for this object. After that code lines p1.name, p1.age and p1.height modifies those default values of the instance variables for this object only. Similarly p2 is also created and assigned the values of instance variables. All the objects of a class are created inside heap memory. You can think of object p1 like below.

Using the () with ClassName calls the constructor of that class to create and initialize the object in memory. We will discuss about constructors in later sections. Let's assume we have two classes Person and MyFirstProgram, code given below shows how to create an object of these classes :
