为int []一个对象？ [英] Is int[] an object?

问题描述

一看，我似乎无法找到一个问题，是与此相同。我的问题是关于 INT [] Java编写的。

Had a look, and I can't seem to find a question that is the same as this. My question is about int[] in Java.

当你创建一个 INT [] ，您可以使用此语法：

When you create an int[], you use this syntax:

int[] x = new int[5];

这是一部分的方法 INT [] 也让我觉得这是一个对象，但它不 ŧ遵循类的Java命名约定，这是什么的困惑我。它也是一个原始类型，它可以像一个原语被用来阵列

The methods that are part of int[] also make me think it's an Object, but it doesn't follow the Java naming convention for classes, which is what's confusing me. It is also an array of a primitive type, which can be used like a primitive.

是 INT [] （或任何基本数组我猜的）一个对象或原始？

Is an int[] (or any primitive array I guess) an object, or a primitive?

推荐答案

在Java中的数组是对象，因此它是一个对象类的子类 - 即使它包含基本类型。您可以检查这一点：

An array in Java is a subclass of Object, therefore it's an object type - even if it contains primitive types. You can check this:

int[] x = new int[5];
if (x instanceof Object)
    System.out.println("It's an Object!");
