Answer / ram

Class.forName () takes the class name as parameter, and
loads that class in memory. But it doesn't create any
instance of that class.

Answer / paras

Class.forName("")loads that class in memory ,to create
instance we have to use newInstance()

string _path="classpath loc of class XYZ ex com.aa.ss.XYZ";

Object ob=Class.forName(_path).newInstance();;
((XYZ)ob).any_method_of_XYZ();

Answer / bharat

when we write the statement
Class.forName("fully qualified path for the class");
then the above statement will do the following things:->
1. loads the specified class (if found) in the memory otherwise throws ClassNotFoundException
2. Returns the object of type java.lang.Class corresponding to the class that was loaded ,In actual this returned object contains all properties of the class that was loaded, In technical words we will say that it is the reflection of the actual class, we can now access all the information about the loaded class with the help of this Class class object, we can now access all the data members , member methods whether they are private or public, all constructors, names of its parent classes, parent Interfaces etc with the help of this Class class object.

Answer / gaurav agrawal

why are you misguiding the people, class.forName("") create
the instance of the class given as argument of the forName
().
first it will load the class in the JVM and after that it
will create the instance.
