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).
