在 Java 中使用不同的返回类型重载? [英] Overload with different return type in Java?

问题描述

为什么不能仅通过更改返回类型来重载函数?这会在 Java 的未来版本中改变吗?

Why is it not possible to overload a function just by changing the return type? Will that change in a future version of Java?

顺便说一句，仅供参考，这在C++中可行吗?

By the way, just for reference, is this possible in C++?

推荐答案

Java 做不到，C++ 也做不到.理由是仅返回值不足以让编译器确定调用哪个函数:

You can't do it in Java, and you can't do it in C++. The rationale is that the return value alone is not sufficient for the compiler to figure out which function to call:

public int foo() {...}
public float foo() {..}

...
foo(); // which one?
