Describe the principle of Java class loader.

Java ClassLoader is based on the following 3 principles.

Delegation principle delegates the classloading request to parent class loader and loads the class only if parent is not able to find or load class.

Visibility principle allows child class loader to access all the classes loaded by parent ClassLoader, while parent class loader cannot see classes loaded by its child.

Uniqueness principle allows to load a class exactly once.
