Java和简单变量C ++ [英] Simple Variables in Java & C++

问题描述

我在一些matrials中看到这个句子：

在Java中，简单的数据类型如int和char的操作与C中一样。

我想知道，他们实际上是不同的Java& C ++？

在C ++中，像Java中的基元的简单变量也被分配一个内存地址，因此C ++中的这些基本类型也可以有一个指针。然而，Java中的基元没有分配一个内存地址，如Objects。

我是否正确？

谢谢！

解决方案

几乎。

在java原语中也分配了内存，但是这发生在内部， p>

这是为了提供内存管理的安全性。

I saw this sentence in some matrials:

"In Java, simple data types such as int and char operate just as in C."

I am wondering that actually they are different in Java & C++?

In C++, simple variables like the primitives in Java are assigned a memory address as well, so these primitive types in C++ can have a pointer as well. However primitives in Java are not assigned a memory address like Objects are.

Am I correct?

Thanks!

解决方案

Almost.

In java primitives are assigned memory as well, but this happens internally and you cannot get the reference.

Thre reason was to provide security on memory management.
