    AspectJ is an aspect-oriented extension created at PARC for the Java programming language. It is available in Eclipse Foundation open-source projects, both stand-alone and integrated into Eclipse. AspectJ has become the widely used de-facto standard for AOP by emphasizing simplicity and usability for end users. It uses Java-like syntax and has included IDE integrations for displaying crosscutting structure since its initial public release in 2001. In this article we will describe how we can use AspectJ to do the logging job for all methods parameters and methods return values in a Java application

So as programmers it's important to keep one's eyes and ears open to the emerging trends so that one doesn't lose out on the potential opportunities.

    In this page, we will learn about the objects and classes. In object-oriented programming, we design a program using objects and classes. Object is the physical entity whereas class is the logical entity. A class works as a template from which we create the objects.

    Inheritance is a mechanism in which one object acquires all the properties and behaviours of parent object. The idea behind inheritance is that you can create new classes that are built upon existing classes. When you inherit from an existing class, you reuse (or inherit) methods and fields, and you add new methods and fields to adapt your new class to new situations.

Java Developers Leery of IBM-Sun Merger - 0 views

  • Java must advance into the new world of the cloud and big developer productivity.
  • Java will become a legacy platform.
  • slow down innovation
  • ...10 more annotations...
  • It would certainly bring us down to two major players on the Java side: IBM and Oracle.
    • Baron M
      Baron M on 01 Apr 09
       
      this is damn TRUE!
  • IBM likes to create these 'boil the ocean' kinds of solutions
    • Baron M
      Baron M on 01 Apr 09
       
      this is the GENERAL PRACTICE of IBM and Oracle
  • IBM could wind up having six different JVM [Java Virtual Machine] implementations
    • Baron M
      Baron M on 01 Apr 09
       
      I like this example... and most likely, this would happen if IBM buys SUN
  • it's a good thing for Sun to get out of the doldrums
  • Every time IBM has bought a company that was in a leadership position, that company seems to have lost market share

      sad but it's a fact...
  • JCP for behaving like a "Russian commissar.
  • Although many have lost faith in the JCP, this is one area where a new steward could really breathe new life into Java
  • the speediest when it comes to keeping their Java technologies up-to-date
  • hold back innovation in support of their own client needs
  • server market would become a bit tighter and that playing field would be altered as well

JavaBlogging » What is serialVersionUID? - 2 views

www.javablogging.com/what-is-serialversionuid java Serializable serialVersionUID
shared by Rinav G on 09 Nov 10 - Cached
  • private static final long serialVersionUID = 1L
  • and it is still there even after the program finished. Let’s see if we can read that file once again, this time without creating it first.
  • Now, let’s see what happens, when we change the serialVersionUID value and try to deserialize once again our file. Change the line 2 in the class SerializeMe so that serialVersionUID contains now 2 instead of 1:
  • ...13 more annotations...
  • serialVersionUID = 2L;
  • static final
  • Exception in thread "main" java.io.InvalidClassException:
  • As you can see, this time the deserialization didn’t go well. ObjectInputStream complained about the serialVersionUID being changed.
  • How does he know that it changed? If serialVersinUID is static, then it should not have been serialized in the first place, and there should be no information about the previous value 1 during the deserialization, right? Well, serialVersionUID is an exception to the rule that “static fields don’t get serialized”.
  • Moreover, if there is no serialVersionUID officially declared in the class to be serialized, compiler automatically adds it with a value generated based on the fields declared in the class.
  • The deserialization of that object does not necessarily have to occur exactly after serialization. It can occur after a few months or on a completely different JVM
  • there is a chance that the class declaration has changed between serialization and deserialization.
  • It checks if the data read from the input stream is compatible with the current definition of the class.
  • when the visibility of a field changes, the serialVersionUID changes too.
  • sometimes you just want for some reason to forbid deserialization of old serialized objects,
  • you might tend to write it once for every serializable class ( or have it generated by the IDE ) and forget about it. WRONG !!!
  • If you write it once and don’t take care to update it when necessary, you loose all the merits of serialVersionUID.
