A Class used to "wrap" (like the name implies) an object..
For example,, the Wrapper class Integer can be used to parse values..
String t = "10";
int t_val= Integer.parseInt(t);
Which gets the numerical value from the String and passes it to the t_val;
Now, there are quite a few usefull wrapper-classes..
like:
Integer
Float
Double
....
Most of them have a capital letter to distinguise them from their
native type...
