Primitive Types vs Wrapper Classes
<p>From what I know, Primitive Types have the following characteristics:</p>

<pre><code>Primitive Type  |  Size   |  Minimum  |     Maximum    |  Wrapper Type
boolean         |1—8 bits |   false   |     true       |  Boolean
char            | 16 bits | Unicode 0 | Unicode 2^16-1 |  Character
byte            |  8 bits |  -128     |     +127       |  Byte  
short           | 16 bits |  -2^15    |     +2^15-1    |  Short
int             | 32 bits |  -2^31    |     +2^31-1    |  Integer
long            | 64 bits |  -2^63    |     +2^63-1    |  Long
float           | 32 bits |  IEEE754  |     IEEE754    |  Float
double          | 64 bits |  IEEE754  |     IEEE754    |  Double
void            |    —    |     —     |        —       |  Void
</code></pre>

<p>I don't know how to implement some sample code using these wrapper classes. How do I?</p>
