Programming Example
Java Runtime Polymorphism Example: Profession
Study this program carefully to understand the logic, output, and explanation in a structured way.
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();
}
}
I am a Teacher I am a Doctor I am a Engineer Press any key to continue . . .
First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.
After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
