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);  
}

Think about an enum that has a string property with a different value then the name of the enum.

public enum FooEnum {
   A("foo"),
   B("bar"),
   ;
  ...
 }

Then you need such an method for a lookup of the property values. See also this answer
