Java - 构造函数是静态的吗? [英] Java - are constructors static?

问题描述

我刚刚写了一个这样的构造函数:

I just wrote a constructor like this:

public ArchivesManager(String identifier) {
    String[] components = String.split("\nNEW");
}

但是有一个错误信息:non-static method split(java.lang.String) cannot be reference from a static context.我知道那个错误信息，但为什么构造函数是静态的?！

But there's an error message: non-static method split(java.lang.String) cannot be referenced from a static context. I know that error message, but why is the constructor static?!

推荐答案

这是因为应该在 String 对象上调用 split.即

It's because split should be called on a String object. I.e.

String foo = "Hello, world";
String[] arr = foo.split(",");
