Java中的引用传递值

Question

Possible Duplicates:
Does Java pass by reference?
Is Java pass by reference?

哎,

是真的Java通过value传递所有东西，而我们不能通过reference传递某些东西吗

谢谢

Answer 1

默认情况下，Java按值传递原语，所有类型的对象引用都按值传递。详见http://java.sun.com/docs/books/jls/third_edition/html/typesValues.html#4.3.1

Answer 2

天哪，不能再问了。Java是按值传递的-总是，在所有情况下。就这样

这里有一个reference引用了詹姆斯·戈斯林的话，他应该对任何人都足够权威：

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.

Answer 3

Java传递您正在传递的对象的引用的值，以及基本类型的简单值。 请参阅以下关于此的讨论： Is Java pass by reference?
