Newer version of IntelliJ IDEA introduces new
[inspection](https://youtrack.jetbrains.com/issue/IDEA-301797/IDEA-should-report-redundant-array-length-check-in-certain-cases)
detecting redundant array length check in snippets like
<T> void iterate(T[] items) {
if (items.length == 0) {
return;
}
for (T item : items) {
//...
}
}
Here
if (items.length == 0) {
return;
}
is redundant and can be removed as length check is performed by for-each loop.
