在Java中通过引用传递原始数据 [英] Passing primitive data by reference in Java

问题描述

是否可以将原始数据作为参数传递给java中的参数，而不将它们包装到相应的类对象中？

is it possible to pass primitive data to a method as argument in java, without wrapping them into corresponding class objects ???

推荐答案

在Java中，无法通过引用传递基元。要模拟它，您必须传递对可变包装类的实例的引用。

In Java, it is not possible to pass primitives by reference. To emulate this, you must pass a reference to an instance of a mutable wrapper class.
