空字符串 [英] Empty string
问题描述
你知道在你发现自己不知道之前你是怎么认识的。
好吧，我输入了一个函数定义...，new String（ "））。
我知道我想要什么。阅读此内容的每个人都知道我想要什么。但是，
1.0编译器不知道我想要什么。
任何人都可以与我分享实际沟通的语法
$ b请给$ b概念编译器？
thx

You know how you assume you know until you find out you don''t know.
Well, I typed into a function definition "..., new String("")).
I know what I want. Everyone reading this knows what I want. However,
the 1.0 compiler has no idea what I want.
Can anyone share with me the syntax that will actually communicate the
concept to the compiler, please?
thx

推荐答案
其实我不确定你想要完成什么。使用new String（）创建一个新的
字符串自动创建零长度字符串。
为什么要使用引号？
最好的问候

Actually I''m not sure what you want to accomplish. Creating a new
string with "new String()" automatically creates a zero length string.
So why use quotation marks?

为什么不使用" ？
创建一个你提供的新字符串对象有点过分了吗
a string-literal（也是一个字符串对象）你希望最终获得相同的价值...
你也可以使用预定义的常量String.Empty。
顺便说一句，1.1已经出来很长一段时间......

Why not use just "" ?
It''s a bit of overkill to create a new string-object that you supply with
a string-literal (which is also a string-object) that has exactly the same
value as you want to end up with...
You could also use the predefined constant String.Empty.
By the way, 1.1 has been out for quite some time ...

我第二个，使用常量String.Empty，而不是使用魔法
值。这只是更好的练习。

I second this, use the constant String.Empty, instead of using a magic
value. It''s just better practice.
