Method Overriding
In Java, when a superclass & subclass method have same signature, then the method in the subclass will override the method in its parent class. When such overridden method is called from a subclass, Java will execute the method defined by the subclass. The version of the method defined by the superclass will be shadowed.
Consider following example:
class Human{
String name;
public String getName(){
return name;
}
public void disp(){
System.out.println("Human");
}
}
class Student extends Human{
int rollNo;
getRollNo{
return rollNo;
}
public void disp(){
System.out.println("Student");
}
}
class demo{
public static void main(){
Human h = new Human();
Student s = new Student();
h.disp();// This would print "Human"
s.disp();// This would print "Student"
}
}
