Explain Java Dynamic class loading ? Java Interview Questions and Answers ?

Loading classes using Class.forName () method. Dynamic class loading is done when the name of the class is not known at compile time

Dynamic Java Class loading is an important feature of the Java Virtual Machine because it provides the Java platform with the ability to install software components at run-time.

It allows you to build your applications so that key external dependencies are not compiled into the application source-code.

String str = "InterviewDot";
Interface clazz = null;
try {
clazz = (Interface )Class.forName(str).newInstance();
} catch (Exception e) {
e.printStackTrace();
}
if (clazz != null) {
clazz.foo();
}
