However, as theArrayListis backed by theEnumvalues array, it’ll be immutable, so we can’t add or remove items from theList.The remove in the following code would fail with anUnsupportedOperationException: List<DaysOfWeekEnum> days = Arrays.asList(DaysOfWeekEnum.values()); days.remove(0); ...

A for loop steps through the elements of an array or a List, just as in Python, though the syntax looks a little different. For example:// find the maximum point of a hailstone sequence stored in li…
With so many optional dependencies in Spring, It's quite common to have numerous Class.forName("something.not.on.the.classpath") calls. The array let's us very quickly answer that question without consuming too much memory. If we cache all entries then those arrays can go, but that's ...
