Java – how to convert an object to an enumeration to use it in a switch statement

Using java 8, I have a map. I need to convert it to another map to replace the key name and sometimes the value For example, when they become enumerations, I need to convert these enumerations to other constants (strings, sometimes integers) I don't want to compare strings, the enum Name(), because there may be duplicates, but I prefer to convert object to enumeration and open it However, I can't find a method to convert object to switchable enumeration Enum. Valueof does not return switchable content (see the example below)

private void put(String key,Object value) {
  if (value != null && value.getClass().isEnum()) {
  Enum<?> val = (Enum<?>)value; 
  /* The below line has the following problem:
   * Cannot switch on a value of type Enum. 
   * Only convertible int values,strings or enum variables are 
   * permitted */
  switch (Enum.valueOf(val.getClass(),val.name())) {
    case EmploymentType.FULL_TIME_EMPLOYEE : value = "Fast anställd";
         break;
    case ResidenceType.TENANCY : value = "Hyresrätt";
         break;
    default : break;
  }
}
map.put(key,value);

}

I know I can:

private void put(String key,Object value) {
  if (value != null && value.getClass().isEnum()) {
    if (value.equals(EmploymentType.FULL_TIME_EMPLOYEE) value = "Fast anställd";
    else if (value.equals(ResidenceType.TENANCY) value = "Hyresrätt";
  }
  map.put(key,value);    
}

But I found it not so elegant and as easy to read as a switch statement Is there any way to do this?

Solution

It seems that you have to deal with multiple enumeration types But you can't switch multiple enumeration types in a switch statement I think you can use map < < enum , Object > instead

You can set up a HashMap like this:

Map<Enum<?>,Object> enumMap = new HashMap<>();
enumMap.put(EmploymentType.FULL_TIME_EMPLOYEE,"Fast anställd");
enumMap.put(ResidenceType.TENANCY,"Hyresrätt");

And use it like this:

if (enumMap.containsKey(value)) {
    value = enumMap.get(value);
}
map.put(key,value);
