Hello Everyone.
The objective of the exercise is to understand that an interface is also a
type.
i.e
String a;
String is the type and a is the reference variable.
interface InterfaceType{
//some code
}
class PersonAddress {
//declare InterfaceType a
private InterfaceType a;
public person (int streetNum, String streetName){
//here pass the constructor arguments into you interface type
a = new InterfaceType(streetNum,streetName);
}
void print(){
system.out.println(a.getStreetNum()) ; // print the getter methods of the
Persons adress
}
}
