      FULL PRODUCT VERSION :
      java version "1.4.1_01"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1_01-b01)
      Java HotSpot(TM) Client VM (build 1.4.1_01-b01, mixed mode)

      FULL OPERATING SYSTEM VERSION :
      MS Windows 2k

      5.00.2195

      A DESCRIPTION OF THE PROBLEM :
      When passed a null value, Integer.parseInt() throws a NumberFormatException.
      However, Double.parseDouble() and Float.parseFloat() throw NullPointerException
      when passed null.


      EXPECTED VERSUS ACTUAL BEHAVIOR :
      I expected to get the same exception (NullPointerException or
      NumberFormatException) in both cases

      REPRODUCIBILITY :
      This bug can be reproduced always.

      ---------- BEGIN SOURCE ----------
      public class test {
      public static int getInt(String value, int defaultValue) {
              try {
                  return Integer.parseInt(value);
              } catch(Exception nfe) {
      nfe.printStackTrace();
                  return defaultValue;
              }
          }

          public static float getFloat(String value, float defaultValue) {
              try {
                  return Float.parseFloat(value);
              } catch(Exception nfe) {
      nfe.printStackTrace();
                  return defaultValue;
              }
          }

          public static void main(String[] args) {
              System.out.println(getInt(null, -1));
              System.out.println(getFloat(null, -1));
          }
      }
