问题描述

推荐答案

此处. [ ^ ]

Java中的关键字"this"的含义与C#和C ++中的完全相同，并且与VB.NET和Delphi中的"self"相同.

这是对可通过非静态方法(也称为实例方法)访问的类型的实例(对象)的引用.从技术上讲，与静态方法/属性相比，它作为附加的隐式参数传递给实例方法或属性.

由于这在命名语言中是完全一样的，因此请查看我过去有关C#和C ++的答案中对它的工作方式的解释:
什么使静态方法可访问? [第22章-接口对象的指针在功能消失时消失使用它们是静态的. [ ^ ].

The keyword "this" in Java means exactly the same as in C# and C++ and, say, the same as "self" in VB.NET and Delphi.

This is a reference to the type''s instance (object) accessible by a non-static method (also called instance method). Technically, it is passed to instance method or property as an additional implicit parameter, in contrast to static methods/properties.

As this is exactly the same thing in the named languages, please see my explanation of how it works in my past answers about C# and C++:
What makes static methods accessible?[^],
Catch 22 - Pointers to interface objects die when function using them is made static.[^].
