原始类型和引用类型之间有什么区别？ [英] What's the difference between primitive and reference types?

问题描述

这是一个过去的考试问题，我想知道原始类型和参考类型首先是什么？
使用数组我知道引用类型是数组由对象或变量组成的位置，但是基本类型是用int或strings创建数组的地方。 （对吗？）

This is a past exam question and I was wondering what a primitive type and reference type are first off? With an array I know the a reference type is where the array is composed of objects or variables, but a primitive type is where you would create the array with just int or strings. (right?)

您认为您如何回答测试中的问题并获得良好的信誉？没有真正直接引用原始的ARRAY类型......有没有办法在没有它的情况下做到这一点？或者你认为用数组解释它会没问题。

How do you think you would answer the question on the test and be given good credit? Without really referring directly to an primitive ARRAY type... Is there a way to do it without that? Or do you think it would be fine to just explain it with the array.

推荐答案

这些是Java中的原始类型：

These are the primitive types in Java:

• boolean


• byte


• short


• char


• int


• long


• float


• double

• boolean
• byte
• short
• char
• int
• long
• float
• double

所有其他类型都是引用类型：它们引用对象。

All the other types are reference types: they reference objects.
