Java String初始化 [英] Java String initialization

问题描述

您更喜欢哪个，为什么？

Which do you prefer and why"

String myString = null;
if(someCondition)
   myString = "something";
else
   myString = "something else";

OR

String myString = "";
if(someCondition)
   myString = "something";
else
   myString = "something else";

我知道使用

推荐答案

两者都不是，相反，

String myString;
if (someCondition)
   myString = "something";
else
   myString = "something else";

在两者中在您的替代方案中，该变量使用永远不会被读取的值进行初始化。事实上，该变量存在是一种误导。

In both of your alternatives, the variable is initialized with a value which will never ever be read. The fact that it's present at all is misleading.

我会实际上当然可以使用条件运算符-但是除非如此，否则上面的方法是更好的选择。

I would actually use the conditional operator, of course - but barring that, the above is the better option.
