Case-insensitive matching of a string to a Java enum

Question

Java provides a valueOf() method for every Enum object, so given an enum like

public enum Day {
         


        

Answer 1

I would think the easiest safe way to do it would be:

Arrays.stream(Day.values())
    .filter(e -> e.name().equalsIgnoreCase(dayName)).findAny().orElse(null);

Or if you want to use the class object, then:

Arrays.stream(enumClass.getEnumConstants())
    .filter(e -> (Enum)e.name().equalsIgnoreCase(dayName)).findAny().orElse(null);
