Java：动态填充数组（不是vector / ArrayList）
||
我试图找出是否有某种方法可以动态填充类中的对象数组，而无需使用数组初始化。我真的很想避免逐行填充数组。考虑到我这里的代码，这可能吗？
final class Attributes {
private final int TOTAL_ATTRIBUTES = 7;
Attribute agility;
Attribute endurance;
Attribute intelligence;
Attribute intuition;
Attribute luck;
Attribute speed;
Attribute strength;
private Attributes[] attributes; //array to hold objects
private boolean initialized = false;
public Attributes() {
initializeAttributes();
initialized = true;
store(); //method for storing objects once they\'ve been initialized.
}
private void initializeAttributes() {
if (initialized == false) {
agility = new Agility();
endurance = new Endurance();
intelligence = new Intelligence();
intuition = new Intuition();
luck = new Luck();
speed = new Speed();
strength = new Strength();
}
}
private void store() {
//Dynamically fill \"attributes\" array here, without filling each element line by line.
}
}

attributes = new Attributes[sizeOfInput]; for (int i=0; i<sizeOfInput; i++) { attributes[i] = itemList[i]; }炬卤遁蝎变
attributes = new Attribute[]{luck,speed,strength,etc};捐焦
Field[] fields = getClass().getDeclaredFields(); ArrayList<Attrubute> attributesList = new ArrayList<Attrubute>(); for(Field f : fields) { if(f.getType() == Attrubute.class) { attributesList.add((Attrubute) f.get(this)); } } attributes = attributesList.toArray(new Attrubute[0]);脾萌
