问题描述

在java中通过引用传递和通过引用调用有什么区别？

what is the difference between pass by reference and call by reference in java ?

推荐答案

Java不会通过引用传递任何变量。

Java does not pass any variables by reference.

考虑通过Java引用传递的对象很有诱惑力但是很有害。对象类型的变量是引用。传递时，它们按值传递。

It is tempting to think of objects being passed by reference in Java -- but harmful. Variables of object type are references. When passed, they are passed by value.

在其他语言中，传递引用和按引用调用是一回事。

In other languages, pass-by-reference and call-by-reference are the same thing.
