本文介绍了获取编译器错误,而在构造函数中使用数组常量的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

public class Sonnet29 implements Poem {
    private String[] poem;
    public Sonnet29() {
        poem = { "foo", "bar" , "baz"};
    }
    @Override
    public void recite() {
      //...
    }
}

诗= {富,酒吧,巴兹}; 是给编译错误

任何具体原因这是不允许的?
我如何初始化字符串数组与数组常量?

Any specific reason why this is not allowed? How do I initialize a String array with array constants?

编辑:谢谢你的乡亲对你的答案。现在我很清楚什么是允许的,哪些不是。
但是,我可以问你的为什么这是不允许的?

Thank you folks for your answers. Now I'm clear what is allowed and what is NOT. But can I ask you why this is NOT allowed?

String[] pets;
pets = {"cat", "dog"};

google搜索了一下后,我发现这链接,其中,被告知,编码这样的叶子在模糊的编译器 - 宠物是否应该是一个字符串数组或对象数组。不过从声明中,它可以很好地弄清楚,它是一个字符串数组,正确的?

After googling a bit, I found this link, where in, it is told that coding like this leaves the compiler in ambiguity - whether the pets should be array of Strings or array of Objects. However from the declaration, it can very well figure out that it is a String array, right???

推荐答案

这会做你要找的内容:

public Sonnet29() {
    poem = new String[] { "foo", "bar", "baz" };
}

创建阵列的新实例初始化时,列表是只允许。

Initialization lists are only allowed when creating a new instance of the array.
