How to get an array from another class
提问by CJ.
I can't seem to find an answer for this, I have a lot of different arrays, and I want to stuff all of them into one class, to make my main one neater.
我似乎无法找到答案，我有很多不同的数组，我想将所有数组都塞到一个类中，以使我的主要数组更整洁。
Testy obj = new Testy();
But i have no clue on how to get an array from here. Sorry if this is a bad question, this is my first time posting on the site. I'm just trying to get an array called testArray from the class called Testy.
但我不知道如何从这里获取数组。对不起，如果这是一个不好的问题，这是我第一次在网站上发帖。我只是想从名为 Testy 的类中获取一个名为 testArray 的数组。
Code inside Testy:
Testy 中的代码：
public class Testy {
public static void ArrayTesting(){
int testArray[]={56,1,4,175};
}}

The standard way to get any variables from another class is to create a getter for that particular variable. After that, you can call the getter in order to get the value of whatever variable you want.
从另一个类中获取任何变量的标准方法是为该特定变量创建一个 getter。之后，您可以调用 getter 以获取您想要的任何变量的值。
Example:
例子：
class MyClass
{
//Variable I want to return
private int[] numArray = {1, 2, 3};
public int[] getNumArray() {
return numArray.clone();
}
}
and you can call it by saying
你可以这样称呼它
MyClass newClassObj = new MyClass();
int[] secondArray = newClassObj.getNumArray();
