809N/A/**
809N/A * There are six methods in java.lang.Integer which transform strings
809N/A * into an int or Integer value:
809N/A *
809N/A * public Integer(String s)
809N/A * public static Integer decode(String nm)
809N/A * public static int parseInt(String s, int radix)
809N/A * public static int parseInt(String s)
809N/A * public static Integer valueOf(String s, int radix)
809N/A * public static Integer valueOf(String s)
809N/A *
809N/A * Besides decode, all the methods and constructor call down into
809N/A * parseInt(String, int) to do the actual work. Therefore, the
809N/A * behavior of parseInt(String, int) will be tested here.
