这个对我很有用:

Arrays.asList(YourEnum.values()).toString().contains("valueToCheck");

你也可以使用:com.google.common.base.Enums

enumes . getifpresent (varEnum.class, varToLookFor)返回一个Optional

enumes . getifpresent (fooenumer .class, myVariable).isPresent() ? Enums.getIfPresent (fooEnum.class myVariable)。get: fooEnum。其他人

  Set.of(CustomType.values())
     .contains(customTypevalue) 

更好的是:

enum choices {
   a1, a2, b1, b2;

  public static boolean contains(String s)
  {
      for(choices choice:values())
           if (choice.name().equals(s)) 
              return true;
      return false;
  } 

};

Java 8+流+设置方式:

    // Build the set.
    final Set<String> mySet = Arrays//
      .stream(YourEnumHere.values())//
      .map(Enum::name)//
      .collect(Collectors.toSet());

    // Reuse the set for contains multiple times.
    mySet.contains(textA);
    mySet.contains(textB);
    ...

如果你使用的是Java 1.8，你可以选择Stream + Lambda来实现:

public enum Period {
    DAILY, WEEKLY
};

//This is recommended
Arrays.stream(Period.values()).anyMatch((t) -> t.name().equals("DAILY1"));
//May throw java.lang.IllegalArgumentException
Arrays.stream(Period.values()).anyMatch(Period.valueOf("DAILY")::equals);
