Java中的布尔值和布尔值有什么区别?

What#39;s the difference between boolean and Boolean in Java?(Java中的布尔值和布尔值有什么区别?)

问题描述

我想了解 Java 中 Boolean 和 boolean 类型之间的区别，特别是它们与 GWT 相关的区别.我知道这些方法不受支持，但如果可用，我想了解更多信息.

I would like to understand the difference between the Boolean and boolean types in Java, specifically as they relate to GWT. I know that methods are not supported but I want more info if it is available.

推荐答案

我不确定 GWT 因素是否有影响，但总的来说:

I'm not sure if the GWT factor makes a difference but in general:

boolean 是 java 原始类型，而 Boolean 是包装布尔值的对象/引用类型

boolean is a java primitive type whereas Boolean is an object/reference type that wraps a boolean

像这样在基元和对象之间进行转换称为装箱/拆箱.

Converting between primitives and objects like this is known as boxing/unboxing.
