* @author Joseph D. Darcy
*/
/**
* There are six methods in java.lang.Integer which transform strings
* into an int or Integer value:
*
* public Integer(String s)
* public static Integer decode(String nm)
* public static int parseInt(String s, int radix)
* public static int parseInt(String s)
* public static Integer valueOf(String s, int radix)
* public static Integer valueOf(String s)
*
* Besides decode, all the methods and constructor call down into
* parseInt(String, int) to do the actual work. Therefore, the
* behavior of parseInt(String, int) will be tested here.
