Getting the Values Out
Java knows how to print wrapper objects, so the easiest way to extract a value is just to print the object: Double d = new Double (3.14159); System.out.println (i); System.out.println (d); Alternatively, you can use the toString method to convert the contents of the wrapper object to a String String istring = i.toString();String dstring = d.toString(); Finally, if you just want to extract the primitive value from the object, there is an object method in each wrapper class that does the job: int iprim = i.intValue ();double dprim = d.doubleValue (); There are also methods for converting wrapper objects into different primitive types. You should check out the documentation for each wrapper class to see what is available.
