什么是“从未使用过分配值”警告意味着？ [英] What does the "Assigned value is never used" warning mean?

问题描述

unformatted = unformatted.replaceAll(seperator, "\n");

Netbeans给我警告：

Netbeans gives me the warning:

永远不会使用指定的变量

The assigned variable is never used

这是什么意思？

推荐答案

这意味着在为其赋值后，您没有对该变量执行任何操作。例如，您不会返回它，使用它执行计算，将其传递给方法或其他任何内容。它基本上意味着在为其赋值后尚未使用该变量。

It means that you're not doing anything with that variable after you assigned a value to it. For example, you are not returning it, performing a calculation with it, passing it to a method, or anything else. It basically means that the variable has not been used after a value has been assigned to it.
