Abstract Base Class or Class?
- by Mohit Deshpande
For my semester project, my team and I are supposed to make a .jar file (library, not runnable) that contains a game development framework and demonstrate the concepts of OOP. Its supposed to be a FRAMEWORK and another team is supposed to use our framework and vice-versa. So I want to know how we should start. We thought of several approaches:
1. Start with a plain class
public class Enemy {
public Enemy(int x, int y, int health, int attack, ...) {
...
}
...
}
public class UserDefinedClass extends Enemy {
...
}
2. Start with an abstract class that user-defined enemies have to inherit abstract members
public abstract class Enemy {
public Enemy(int x, int y, int health, int attack, ...) {
...
}
public abstract void draw();
public abstract void destroy();
...
}
public class UserDefinedClass extends Enemy {
...
public void draw() {
...
}
public void destroy() {
...
}
}
3. Create a super ABC (Abstract Base Class) that ALL inherit from
public abstract class VectorEntity {
...
}
public abstract class Enemy extends VectorEntity {
...
}
public class Player extends VectorEntity {
...
}
public class UserDefinedClass extends Enemy {
...
}
Which should I use? Or is there a better way?
