There are 4 ways to create object:

1.using new operator
Employee obj=new Employee();
Except this one

2.using factory methods
NumberFormat obj=NumberFormat.getNumberInstance();

3.using newInstance() method
Class c=Class.forName("Employee");
Employee obj=(Employee)c.newInstance();
or we can write these two lines as a single line
Employee obj=
(Employee)Class.forName("Employee").newInstance();

4.By cloning
Employee obj1=new Employee();
Employee obj2=(Employee)obj1.clone();
