There are 4 ways of creating objects in java.
1.Using new operator :
Employee obj=new Employee();
Here we are creating Employee class object ‘obj’ using new operator.
2.Using factory methods :
NumberFormat obj=NumberFormat.getNumberInstance();
Here, we are creating NumberFormat class object using factory method getNumberInstance().
3. Using newInstance() method. Here, we should follow two steps, as:
a.First, store the class name ‘Employee’ as a String into a object. For this purpose, factory method forName() of the class ‘Class’ will be useful.
Class c=Class.forName(“Employeeâ€);
b.Next, create another object to the class whose name is in the object c. For this purpose, we need newInstance() method of the class ‘Class’, as:
Employee obj=(Employee)c.newInstance();
4.By cloning a already available object, we can create another object. Creating exact copy of a existing object is called ‘cloning’.
Employee obj1=new Employee();
Employee obj2=(Employee)obj1.clone();
