Run-Time Polymorphism: Runtime polymorphism occurs when an object is associated with functionality during runtime. Method overriding can be used to provide runtime polymorphism. The Java virtual machine selects the method to invoke during runtime, not at compile time. It’s also known as dynamic...
In the last tutorial we discussedPolymorphism in Java. In this guide we will seetypes of polymorphism. There are two types of polymorphism in java: 1)Static Polymorphismalso known as compile time polymorphism 2)Dynamic Polymorphismalso known as runtime polymorphism Compile time Polymorphism (or Stat...
Since Java 5, it is possible to override a method by changing its return type, If subclass override any method by changing the return type of super class method, then the return type of overriden method must besubtype of return type declared in origin methodinside the super class. this is ...
Which component is responsible for running a Java program - Java Runtime Environment (JRE) JRE is a part of the Java Development Kit (JDK), which is responsible for executing a Java program. It acts as a mediator between the Java program and the OS. This
JavaObject Oriented ProgrammingProgramming Runtime Type Identification in short RTTI is a feature that enables retrieval of the type of an object during run time. It is very crucial for polymorphism as in this oops functionality we have to determine which method will get executed. We can also ...
In other languages like C# or Java, users are allowed to acquire detailed metadata of a type-erased type at runtime with simple APIs, but this is not true for std::function, std::any or inheritance-based polymorphism in C++. Although these reflection facilities add certain runtime overhead...
Making Polymorphism faster Ok, so now that we have seen the benefits of polymorphism, let’s assume that we have decided it is indispensable in the design of our game’s code but the performance is still a concern. One way to improve the performance and still retain the benefits is to ad...

We describe an efficient compiler and run-time system for NextGen, a compatible extension of the Java programming language supporting run-time generic types designed by Cartwright and Steele. The resulting system is comparable in performance with both st
In this paper, new dynamic cohesion metrics are proposed which provide scope of cohesion measurement up to the object level and take into account important and widely used object-oriented features such as inheritance, polymorphism and dynamic binding during measurement. The proposed dynamic measures ...
