What is benefit from using fromValue function instead of valueOf, java enums?

I see some programmers use in enums structure function called fromValue. What is it purpose, if we can use valueOf? For example, I found something like this:

public static FooEnum fromValue(String v) {  
    return valueOf(v);  
}
Solution

  • You may have an invalid String value:

    public static FooEnum fromValue(String v) {
    try {
        return valueOf(v);
    } catch (InvalidArgumentException e) {
        return FooEnum.UNKNOWN;
    }
}
