Switch statements:
public boolean beats(GameObject object){
if（object.getClass.getName(0.equals("Rock"){
result=false;
}
else if（object.getClass.getName(0.equals("Rock"){
result=false;
}else if（object.getClass.getName(0.equals("Rock"){
result=false;
}
return result;
}
Doulbe Dispatch Pattern:
public class Rock implements GameObject{
public boolean beats(GameObject o){
return o.beatsRock();
}
public beatsRock(){
return false;
}... 阅读全帖 |
