Java：动态填充数组（不是vector / ArrayList） [英] Java: Dynamically Fill Array (not vector/ArrayList)

问题描述

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。

I'm trying to figure out if there's someway for me to dynamically fill an array of objects within a class, without using array initialization. I'd really like to avoid filling the array line by line. Is this possible given the code I have here?

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.
    }
}

推荐答案

attributes = new Attributes[sizeOfInput];

for (int i=0; i<sizeOfInput; i++) {
    attributes[i] = itemList[i];
}

此外，仅供参考，您可以将内容添加到ArrayList中，然后调用toArray（）获取对象的数组。

Also, FYI you can add things to an ArrayList and then call toArray() to get an Array of the object.
