Single Inheritance n It allows the creation of user defined data types, Polymorphism OOP having the properties ofParadigm built data types and a set Persistence of permitted operators. Delegation n In Java, partial support. n In C++, fully supported Genericity (e.g., operator overloading). Multiple Inheritance 11
