+/**
+ * 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.
