Will I have a hand on these???!

Programming Languages Generations "Programming Levels of Abstraction"

Programming Languages Generations "Programming Levels of Abstraction" 

• 1GL: First Generation progrmmming Language which is about Machine Language and it is read directly by CPU and almost nobody programs with it.
  
• 2GL: higher Level of Abstraction and contains the different types of Assembly languages which depends on the computer architecture.
• 3GL:  more enhancement in the 2GL to be reusable and more user-friendly such as C, Fortran, Java.
• 4GL: Domain-specific prgramming Language used for Rapid Application Development "Drag & Drop fashion, templates with customization", it is an umbrella term contains many languages such as LabView, Matlab, PL/SQL etc.; it concerns with these objectives Codeless,  Problem Solving and System Engineering.
  
• 5GL: The highest level of abstraction which is based on the contraint programming rather than coding algorithms such as Prolog and Mercury.

What I can conclude is that, even if it seems the natural development of programming languages is to be a higher level of abstraction, I think the Highest generation will combine both lowest and highest level of abstraction together in a cyclic hybrid fashion not a finite timeline as may others thought. Therefore, if 6GL will be existed, it will concern about an application template that can be customized for acertain need in a domain and in the same time can be modified to achieve a puropse of another domain.

A new web technology that has alot of features of OOP and provide the scalability of desktop programs on a browser... this technology depends on javascript mostly

Java Modifiers

• Final class cannot be extended.

• Final method cannot be overridden.

• Final attribute

– must be initialized in class or constructor.

– once it is given a value, it cannot be changed.

– final object variable, it is the reference that cannot be changed not its value.

• Abstract class cannot be instantiated.

• Abstract method must be defined in abstract class, but abstract class may

contain non-abstract method.

• Abstract method cannot implement method body.

• Abstract never matches with final, only with protected and public.

• Local variable cannot be defined as static

• Static method cannot overridden non-static method and vice versa.

• Static methods are not allowed to use a non-static feature of their class, but not

vice versa.
