Java 是否通过引用传递?

嘿，

是不是Java都是通过value来传递的，而我们不能通过reference来传递?

Is it true that Java passes everything by value, and we can't pass something by reference ?

谢谢.

推荐答案

天哪，不能再问了.Java 是按值传递的 - 总是，在所有情况下.就是这样.

Good God, it can't be asked again. Java is pass by value - always, in all cases. That's it.

这是引用 James Gosling 的 参考，谁应该对任何人都足够权威:

Here's a reference that quotes James Gosling, who should be authoritative enough for anyone:

来自 Java 的作者:有正好是一种参数传递模式Java - 按值传递 - 这有帮助保持简单."Java编程语言，第 2 版.肯阿诺德和詹姆斯高斯林，部分2.6.1，第 40 页，第 3 段.

From the authors of Java: "There is exactly one parameter passing mode in Java - pass by value - and that helps keep things simple." The Java Programming Language, 2nd ed. by Ken Arnold and James Gosling, section 2.6.1, page 40, 3rd paragraph.
