What is the difference between compile-time polymorphism and run-time polymorphism?

Polymorphism is one of the most important OOP concepts. This is a concept where we can perform a single task in multiple ways. There are two types of polymorphism, one is compile-time polymorphism and the other is run-time polymorphism.

Method overloading is an example of compile-time polymorphism, and method overriding is an example of run-time polymorphism.

Advanced.	Key	Compile-time polymorphism	Run-time polymorphism
1	Basic	Compile-time polymorphism means binding occurs at compile time	Run-time polymorphism property, at runtime we know which method will be called
2	static/dynamicBinding	##can be achieved through static binding

Compile-time polymorphism example

public class Main {
   public static void main(String args[]) {
      CompileTimePloymorphismExample obj = new CompileTimePloymorphismExample();
      obj.display();
      obj.display("Polymorphism");
   }
}
class CompileTimePloymorphismExample {
   void display() {
      System.out.println("In Display without parameter");
   }
   void display(String value) {
      System.out.println("In Display with parameter" + value);
   }
}

Run-time polymorphism example

public class Main {
   public static void main(String args[]) {
      RunTimePolymorphismParentClassExample obj = new RunTimePolymorphismSubClassExample();
      obj.display();
   }
}

class RunTimePolymorphismParentClassExample {
   public void display() {
      System.out.println("Overridden Method");
   }
}

public class RunTimePolymorphismSubClassExample extends RunTimePolymorphismParentExample {

   public void display() {
      System.out.println("Overriding Method");
   }
}
