java - What does //noinspection ForLoopReplaceableByForEach mean?

Question

I have been reading some open source libraries which use the following code:

//noinspection ForLoopReplaceableByForEach
for (int i = 0, count = list.size(); i < count; i++) {
  // do something
}

What does //noinspection ForLoopReplaceableByForEach mean?

//noinspection是 IntelliJ 特定的注释。它与 Java 类似，@SupressWarnings只是它可以用于单个语句，而不是在类或方法级别将其声明为@SupressWarnings.

在这种情况下，它会抑制 For 循环可以被 ForEach 替换的警告。

这意味着您正在使用计数器来遍历列表，而您可以这样做：

for (Object obj : list)

其中 Object 被列表中对象的类型替换。
