Evolution of Not



  • Today while hunting down a bug for a Java 1.4 application that I maintainI ran into a piece of code that I thought was rather odd.

    function someFunc(String field, boolean flag) {

      if(field.equals("thing_one")) return delegate.getValue(1, flag ? false : true);

      else if(field.equals("thing_two")) return delegate.getValue(2, flag ? false : true);

      ..snip 60 more else ifs..

    }

     

    I looked into the history of this function and saw

    function someFunc(String field, boolean flag) {

      if(field.equals("thing_one")) {

        if(flag) {

          return delegate.getValue(1, false);

        } else {

          return delegate.getValue(1, true);

        }

      } else if ...snip 60 more else if....

    Someone is going to be blown away when they find out about the not-operator.

     

    Oh and TRWTF is Java 1.4, stupid non-autoboxing jerk with no support for Generics.

    Indeed, I can't see any reason for 1.4 still hanging around in the corners. Is >=1.5 really that massively different that it's hard to update? What's so magical about 1.4 anyway?

    They might even be surprised to discover that none of the elses in your quoted code serve any purpose but decoration!

    Not to mention the idea of putting those 'things' in an array and using for loops. You know, like actually searching for a string.

    1.4 is the last Java for toasters. The runtime bloated up quite a bit with 1.5.

     

    Also, I think one non-sun VM is stuck at the 1.4 feature level (probably because its biggest/only customer runs it on toasters), and some people insist on not excluding it for some reason.

    Nothing. It is just still being in use in some products that I develop for. Such as IBM WebSphere Application Servers version 6. And my employer usually only upgrades if there is no other way, such as no more support from the manufacturer.

    Therefore: I hail you all who can use all of these nice new features of Java 1.5 and beyond. Only, it is not for me, at least not until some time... Autoboxing? I can do without. Templates? tough luck.

    Well, yes, it might be TRWTF to use WebSphere. But in some shops, you just can't upgrade whenever you feel like it. Such a step might cost millions in retesting, or may require changing code or configuration. Not something you do overnight.

    Are you telling me that Cylons actually run Java 1.4?

    Well, Sun supports 1.4 no more.

    I'd add that while I welcome lots of improvements with 1.5, Java EE 5 FUBAR'd some things there; Sun decided to eviscerate Entity Beans, so all my J2EE know-how was put upside down. Fortunately my current job uses 1.4, so I'm not in a hurry to "relearn the wheel" yet.
