为什么没有办法在java中通过引用传递 [英] Why there is no way to pass by reference in java

问题描述

我猜java没有选项按参考传递。但为什么？因为有时非常需要它。

I guess java does not have the option "pass by reference" .But why ? Because sometimes it is very needed.

推荐答案

任何时候你觉得需要通过引用传递一个值，而是传递一个引用来值。虽然Java没有通过引用传递机制，但它确实有引用。所以只需按值传递这些引用。

Any time you feel the need to pass a value by reference, instead pass a reference by value. While Java does not have a "pass by reference" mechanism, it does have references. So just pass those references by value.
