Detect a boxing class [duplicate]

Question

Is there a way to know if a given class is a class that boxes a primitive type or do I have to make an ugly method like this :

public boolean isBoxingClass(Class clazz){
  String simpleName=clazz.getSimpleName();
  switch(simpleName){
    case "Integer":
    case "Long":
    case "Boolean":
    case "Double":
    case "Float":
      return true;
    default :
      return false;
  }
}

EDIT:

If finally opted for this solution :

public static final List<Class> BOXING_CLASSES= Arrays.asList(new Class[]{
      Integer.class,
      Long.class,
      Short.class,
      Boolean.class,
      Double.class,
      Float.class,
      Character.class,
      Void.class,
      Byte.class});

public static boolean isBoxing(Class clazz){
  return BOXING_CLASSES.contains(clazz);
}

Answer 1

This is the simplest way I could think of. The wrapper classes are present only in java.lang package. And apart from the wrapper classes, no other class in java.lang has a variable named TYPE. You could use that to check whether a class is Wrapper class or not.

public static boolean isBoxingClass(Class<?> clazz)
{
    String pack = clazz.getPackage().getName();
    if(!"java.lang".equals(pack)) 
        return false;
    try 
    {
        clazz.getField("TYPE");
    } 
    catch (NoSuchFieldException e) 
    {
        return false;
    }           
    return true;        
}
