为什么 Java 数组声明使用大括号? [英] Why do Java array declarations use curly brackets?

问题描述

我想知道为什么 Java 数组声明使用大括号而不是标准括号.如此处所示.我想这可能需要进一步了解大括号，但这具体是我现在的议程.

I would like to know why Java array declarations use curly brackets as opposed to the standard parenthesis. As illustrated here. I imagine this may take further understanding of curly brackets in general, but this specifically is on my agenda right now.

Object[] tableHeaders = {"Cars","Trucks","Tacos"};

这是正确的，而不是.

Object[] tableHeaders = ("Cars","Trucks","Tacos");

推荐答案

大括号通常表示集合和集合，而括号通常表示类 C 语言中的参数.

Curly brackets usually denotes sets and ensembles while parenthesis usually denotes parameters in C-like languages.

很久以前，人们已经习惯了这种约定C.我很确定它在 Java 中以这种方式工作，以保持与旧语言的某种语法一致性.

A long time ago, people got used to having this kind of convention with C. I'm pretty sure that it works this way in Java to keep some kind of syntax consistency with older languages.
