i've read a lot of blogs, tutorials & co but i don't get something about the dynamic binding in java. When i create the object called "myspecialcar" it's creates an object from the class "car" as type of the class vehicle as a dynamic binding right? So java know that when i execute the method myspecialcar.getType() i have a car object and it execute the method from the class car. But why i got the type from the class vehicle? Is that because the variable from the class vehicle (type) is a static binding?
Regards,
Code:
public class vehicle {
String type = "vehicle";
public String getType(){
return type;
}
}
public class car extends vehicle {
String type = "car";
public String getType(){
return type;
}
}
public class test {
public static void main (String[] args){
vehicle myvehicle = new vehicle(); // static binding
car mycar = new car(); // static binding
vehicle myspecialcar = new car(); //dynamic binding
System.out.println(myspecialcar.getType());
System.out.println(myspecialcar.type);
System.out.println(myspecialcar.getClass());
}
}
Output:
car
vehicle
class car
