Answer / aslam

If we know the class name during the compile time, we must
use the keyword "new". because this creates much faster
than the second method. But if we get the class name only
on run time, we have to use Class.forName
("classNameAsArgument").newInstance(); Here we can pass the
class name as a string argument. We can't achieve this with
the keyword "new".

Answer / qim2010

Java’s “new” operator is used to load the class statically.

class MyClass {
public static void main(String args[]) {
Car c = new Car();
}
}

Class.forName (String className); is used for dynamic class
loading. The string className can be supplied dynamically at
run time. Once the class is dynamically loaded the following
method returns an instance of the loaded class. It’s just
like creating a class object with no arguments.

class.newInstance (); //A non-static method, which creates
an instance of a
//class (i.e. creates an object).
