Java – Instance Members

Instance Members:

• Instance members also called non-static members.
• Instance members related to Object.
• We invoke instance members using Object-address

Object Creation of a Class in java:

Syntax:           ClassName ref = new ClassName();

Example:        Employee emp = new Employee();

Constructor:

• Defining a method with Class-Name.
• Constructor Not allowed return-type

class Employee {             Employee()             {                         System.out.println(“Constructor”);             } }

We must invoke the constructor in Object creation process:

class Employee {             Employee()             {                         System.out.println(“Object created”);             }             public static void main(String args[])             {                         Employee emp = new Employee();             } }
