  • Java is allowed to extend more class to one class. So that java is not supporting Multiple inheritance. One or more interfaces can implement with a Java Class.
  • In Java, classes may extend only one superclass. Classes that do not specify a superclass with extends automatically inherit from java.lang.Object.
  • The syntax for Java generics bounded wildcards, representing the unknown type by ? is: ? extends T represents an upper bounded wildcard.

  • Dynamically extend Java applications. Use interfaces and dynamic class loading for added functionality.
