Hello Isabel,
Although I haven't yet taken the certification, I still believe that what you need to know about the Wrapper classes is found in the
java api documentation. As I could notice as far as it regards the topics, it should be enough for the certification purpose to know :
- which are the Wrapper classes (all the primitive type asscociated classes like Integer for int, Long for long, etc.)
- the constructors of this classes (for example: Float constructor can take as parameter also a double since Byte can take only a byte or a
String)
- which of those classes have methods that return primitive values
- the equals() method
If I missed something please guys complete/correct me
Cheers
