since its introduction in java 8, the stream api has become a staple of java development. the basic operations like iterating, filtering, mapping sequences of elements are deceptively simple to use. but these can also be overused and fall into some common pitfalls. to get a better understandi...
With the above class definition, when we invoke thesum()method in the program, based on argument types, the compiler decides which method to call on the compile time only, and generates the bytecode accordingly. This is called compile-time polymorphism. ...
We won't discuss why this is dynamic, but let's just say that Java decides what method to call during runtime, or once the program is running. Dynamic method binding is how Java decides what method to call when it has to decide between the superclass and the subclass. So, how exactly...

Java is an object-oriented language. Foundations of any object oriented language are laid on three pillars: Polymorphism, Inheritance and Encapsulation. Inheritance refers to the ability of a class to extend another class without having to rewrite the code in the parent class. Inheritance fosters co...
In this possible approach, we are going to apply the con_str method to demonstrate the working of compile time polymorphism by changing the number of parameters. String con_str = s1 + s2; System.out.println("Concatenated strings :"+ con_str); Example Open Compiler //Java program to demo...

Polymorphism—or an object’s ability to execute specialized actions based on its type—is what makes Java code flexible. Many design patterns created by the Gang Of Four rely on some form of polymorphism, including the Command pattern. In this article, you will learn the basics of Java ...
In the last tutorial we discussed Polymorphism in Java. In this guide we will see types of polymorphism. There are two types of polymorphism in java: 1) Static Polymorphism also known as compile time polymorphism 2) Dynamic Polymorphism also known as run
