Amazing content. I was stuck for a while trying to write JUnit tests and compiling several data structures in multiple packages. What a great tutorial.

I hope this was clear but you can add more packages to your bin folder, and import them into any class. For example if I added this package from say 'www.fighting.com' (made up name) to my bin folder:

package com.fighting.combat;
//
public interface Attackable {
void setHealth(double health);
double getHealth();
double getSize();
}

Then I could use it in my Frog class like this...

package animals.amphibians;
import
//
public class Frog implements Attackable {
private double health, size;

public void speak() {
System.out.println("Ribbit");
}

public Frog() {
health = 100;
size = 16;
}

public void setHealth(double health) {
this.health = health;
}

public double getHealth() {
return health;
}

public double getSize() {
return size;
}
}
