Converting a Primitive Type Value to a String</h3>
There are two ways to convert a primitive type value into a string.
The explicit way is to call <code>String.valueOf()</code>. The implicit way is
to use the string concatenation operator `<code>+</code>'.
<pre>
// Use String.valueOf()
String s = String.valueOf(<font color="#0066ff"><i>true</i></font>); // true
s = String.valueOf((byte)<font color="#0066ff"><i>0x12</i></font>); // 18
s = String.valueOf((byte)<font color="#0066ff"><i>0xFF</i></font>); // -1
s = String.valueOf(<font color="#0066ff"><i>'a'</i></font>); // a
s = String.valueOf((short)<font color="#0066ff"><i>123</i></font>); // 123
s = String.valueOf(<font color="#0066ff"><i>123</i></font>); // 123
s = String.valueOf(<font color="#0066ff"><i>123L</i></font>); // 123
s = String.valueOf(<font color="#0066ff"><i>1.23F</i></font>); // 1.23
s = String.valueOf(<font color="#0066ff"><i>1.23D</i></font>); // 1.23
// Use +
s = ""+<font color="#0066ff"><i>true</i></font>; // true
s = ""+((byte)<font color="#0066ff"><i>0x12</i></font>); // 18
s = ""+((byte)<font color="#0066ff"><i>0xFF</i></font>); // -1
s = ""+<font color="#0066ff"><i>'a'</i></font>; // a
s = ""+((short)<font color="#0066ff"><i>123</i></font>); // 123
s = ""+<font color="#0066ff"><i>123</i></font>; // 123
s = ""+<font color="#0066ff"><i>123L</i></font>; // 123
s = ""+<font color="#0066ff"><i>1.23F</i></font>; // 1.23
s = ""+<font color="#0066ff"><i>1.23D</i></font>; // 1.23
