Persontype. Thus, you can pass an object of thePersontype or theEmployeetype when you call theDisplay()method. TheDisplay()method does not know the type of parameter you passed at compile time. It can be anything at runtime. That's why method overriding is called run-time polymorphism....
Method Overloading is done in the same class. Method Overloading gives better performance. In case of Method Overloading, return type of a method does not matter (means it will be same or different). Method Overriding: Method Overriding happens at run time. Static methods cannot be overridd...
You can use metadata to allow run-time polymorphism, this metadata can be used to cast an object to be cast object. 在示范的媒体实现中,处理器可执行指令所引起的操作包括:在运行时间环境中时,至少发现对象的一种类型;以及,通过使用元数据将该对象强制转换为该被转换对象,从该对象中创建被强制转换对象....
As method overloading is resolved at compile time it is an example ofcompile-time polymorphism. It enhances the readability of a program as it improves the overall structure of the code. Method Overloading Example File: Test.java importjava.io.*;classAddition{voidadd(intc,intd){System.out....
Method overloading and Method overriding is used to achieve polymorphism in Java. We should have an understanding of Inheritance and aggregation to know them.
