| * There are seven 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(CharSequence s, int beginIndex, int endIndex, int radix) |
| * 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(CharSequence, int, int, int) to do the actual work. Therefore, the |
| * behavior of parseInt(CharSequence, int, int, int) will be tested here. |
