当类构造函数具有参数时，如何在Java中初始化数组? [英] How to initialize array in java when the class constructor has parameters?

问题描述

我有这个类的构造函数:

I have this class constructor:

public Category(int max){
...
}

问题是，我想创建一个此类的数组，如何初始化它?

The thing is, I want to make an array of this class, how do I initialize it?

private Category categories = new Category(max)[4];

不起作用.

UPDATE

UPDATE

我需要做这样的事情吗?

Do I need to do something like this?

private Category[] categories = new Category[4];

然后初始化每个对象?

推荐答案

在创建数组时，您正在创建Category数组.那是数组的一个实例.

When you are making an array , you are creating an array of Category. That s an instance of array.

在使用Category对象填充数组时，此时将使用带有Const的Category.

When you are populating the array with Category objects, at that point you use the Category with Const.

Category [] categories = new Category[4];
categories[0] = new Category(10);
