From the API for the Wrapper classes(Boolean/Byte/Integer..) ------------ public boolean equals(Object obj) Compares this object to the specified object. Parameters: obj - the object to compare with Returns: true if the objects are the same; false otherwise. Overrides: equals in class Object

maha anna bartender	posted February 20, 2000 11:59 AM              Tony has got a point. It we OVERRIDE the .equals(Object o) method then we have define the hashCode() also. This method should return the same value for objects that compare equality using this equals(Object o) method. maha anna
