Makes sense to me
Posted by Kishori Sharan on July 27, 2001 at 8:09 PM
Hi
This is correct and makes sense if you implement the Talkative interface in Animal class so that your Cat class will inherit it. The code which you are saying doesn't work on your PC works on mine. The following code compiled and ran on my PC. If it still doesn't run then tell me the following things.
1. Version of Java
2. Are placing classes in packages. If yes then how
3. What command you are using to compile and run your classes. Thanks
Kishori /////////Interrogator.java
interface Talkative{
void talk();
} abstract class Animal implements Talkative {
public void talk() {
}
} class Cat extends Animal {
public void talk() {
System.out.println("meow meow");
}
} class Interrogator {
void letsMakeItTalk(Talkative subject){
subject.talk();
}
public static void main(String[] args){
Cat c = new Cat();
new Interrogator().letsMakeItTalk(c);
}
}
