Java不能重载任何运算符.为什么? [英] Java cannot overload any operators. Why?

问题描述

可能重复:
Java运算符重载

Possible Duplicate:
Java operator overload

在c ++中，我们可以执行运算符重载.但是Java还是一种面向对象的语言.那么，为什么Java不支持重载呢?

In c++, we can perform the operator overloading. But Java is also a Object oriented language. So why java doesn't support overloading?

推荐答案

实际上，它确实支持运算符重载……这是非常有限的，仅内置的.例如，除了常用的运算法则外，String的"+"也已重载.

Actually, it does support operator overloading... of a very limited, built-in only nature. For instance "+" is overloaded for String's in addition to the usual arithmetic.

当然，大多数人都想知道Java为什么不支持用户定义的运算符重载. :-)最简单的答案似乎是，当时的Java创建者没有看到任何干净的方法将其添加到语言中，而不会在过程中使Java混乱(如C ++).

Of course, most people want to know why Java does not support user-defined operator overloading. :-) The simplest answer seems to be that the Java creators did not, at the time, see any clean way to add it to the language without making Java a mess (like C++) in the process.
