Using Objects

• Objects are instances of classes. for example to declare an object of Employee class type:

	Employee emp ;
	

• To instantiate (allocate memory and initialize) an object key word new is used:

	emp = new Employee() ;
	

• Objects can be declared and instantiated at the same time:

	Employee emp = new Employee() ; 
	

• To access an object methods it has to be instantiated. To access a method DOT . (access operator) is used

	emp.print();  // calls the print method associated with Employee class
	String name = emp.getName() ;
