用Java创建数组(C ++样式) [英] Creation of Arrays in Java (The C++ Style)

问题描述

为什么我们不能在Java中这样创建数组:

Why can't we make arrays in Java like this:

int marks[5];

并在此声明后分配值?

任何人都请解释一下术语或区别.

Anyone please explain the terminology or difference.

推荐答案

这是因为Java中没有堆栈数组.这等效于Java:

This is because there are no stack arrays in Java. Here is Java equivalent:

int[] marks = new int[5];

它看起来很像在C ++中分配动态大小的数组.当然，您不必担心调用 delete [] ，因为它是垃圾回收.

It looks a lot like allocating dynamically-sized arrays in C++. Of course you don't have to worry about calling a delete[], because it's garbage collected.
