Learn this program step-by-step with algorithm, source code, output and detailed explanation.

💻 Program Code


class Prefession{
void check(){
	System.out.println("I am check method of parent class");
	}
}

  class Teacher extends Prefession{
	void check(){
	System.out.println("I am a Teacher");
	}
  }

  class Doctor extends Prefession{
	void check(){
	System.out.println("I am a Doctor");
	}
   }

  class Engineer extends Prefession{
	void check(){
	System.out.println("I am a Engineer");
	}
}

class RunTimePolymorphism{
public static void main(String args[]){
Prefession obj;
obj=new Teacher();
obj.check();

obj=new Doctor();
obj.check();

obj=new Engineer();
obj.check();
}
}
