Answer / mohan reddy
In 3 ways we can able to create object without using "new"
operator.
1)Using a Static Factory Method
ABC.getInstance();
2)Using newInstance() method...
class A=(A)Class.forName("A").newInstance();
3)Using clone() method.

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();

Answer / seshu godavarthi
when the class is declared as static we can create an
object for the class without instantiating or without using
new operator...we can access the variables or methods in
the class by using the classname
