Upcasting When reference variable of Parent class refers to the object of Child class, it is known as upcasting. In the code "{ exec >/dev/null; } >/dev/null" what is happening under the hood? Method overloading means there are several methods present in a class having the same name but different types/order/number of parameters. Reply Shashi says December 3, 2015 at 12:37 PM The method overriding is an example of runtime polymorphism. this contact form

An important example of polymorphism is how a parent class refers to a child class object.  In fact, any object that satisfies more than one IS-A relationship is polymorphic in nature. if class Y extends class X then both of the following statements are valid: Y obj = new Y(); //Parent class reference can be assigned to child object X obj = What's the right answer to "Check, Savings or Credit" for an overseas card in Australia? In this kind of polymorphism, reference of class X can hold object of class X or an object of any sub classes of class X.

Compile Time Polymorphism In Java

Compile time Polymorhism( or Static polymorphism) Compile time polymorphism is nothing but the method overloading in java. If method has different signature, then different return type is fine. public class X { public void methodA() //Base class method { System.out.println ("hello, I'm methodA of class X"); } } public class Y extends X { public void methodA() //Derived Class In this Mechanism by which a call to an overridden function is resolved at a Run-Time.

its just because of missing return type for the above static method and respected returning values.other wise rest of thing works fine. Open Source GPL 2.0.

Keep it up Sandeep. weblink Here, Cat satisfies the IS-A relationship for its own type as well as its super class Animal. Since it refers to the subclass object and subclass method overrides the Parent class method, subclass method is invoked at runtime. Type of object on which method is being invoked is not known at compile time but will be decided at run time. Runtime Polymorphism In Java

is it true or, what about this line I am writing down- May have different return types if argument list Type is different. Runtime Polymorphism In C# Example When different types of documents need to be serialized/de-serialized, the document objects will be referred by the ‘ Document’ class reference (or pointer) and when the ‘ Serialize() ’ or ‘ static method is a class level method , where as plain method is a object level method , so that both method is not same .

Ex wait(), notify(), equals(), etc.

So, the move() method of Vehicle will be called. Polymorphism is a concept of object. thks divya Thanks!! Dynamic Polymorphism In C++ Responsive. 100% Free.

Less memory space Less execution time More performance Static polymorphism The process of binding the overloaded method within object at compile time is known as Static polymorphism due to static polymorphism Now, if we call the overridden method on the super class reference then the sub class version of the method will be called. current community chat Stack Overflow Meta Stack Overflow your communities Sign up or log in to customize your list. http://evollux.net/polymorphism-in/compile-time-polymorphism-and-runtime-polymorphism-in-java.html Dynamic Binding/Runtime Polymorphism : Run time Polymorphism also known as method overriding.
