i think answer should be:
float,long,double.
Reason: all the data types that can be implicitly converted to int can be used for switch case. Integer is right answer only for java 5 because it allows autoboxing/unboxing.
Please correct me if i am wrong

You can't use Integer (Wrapper) in statement as a argument.
