hi javaranchers!
the question may sound stupid for you all but is a genuine one for me.i want to make a carrer shift to IT.(my backround is a doctorate in physics).i haven't done any real coding though i have a little knowledge of programming in C++.Will JAVA CERTIFICATION helps in securing a job without any previous experience of programming?All options are appreciable.
rekha


The query as answered by Sun themselves....
Q. WHY SHOULD I BECOME CERTIFIED?
A. Certification validates a certain level of competency in programming for the Java platform. With Java technology in use for so many critical applications, companies looking to take on Java technology professionals are more likely to look for Sun Certification - after all, Sun pioneered the Java platform and is therefore fully committed to its future. Programmers and developers can gain the skills needed to advance their careers, while managers can make certain their staff are highly trained in Java technology, increasing productivity and ensuring staff have the right skill levels.

1}--To answer the first question, I think the answer lies in the inner class declaration called Anonymous classes where u just declare a class inside a parameter declaration bracket of a method. The point here lies in just the declaration with the word "new" which implicitly recognises its duty to implement or to extend "without actually specifying it".
2) The first part of the nested class's importance can be very well understood by examining the eventlisteners, where they are used in plenty.
Hi,
To get a better idea, please refer the API. Socket is a class in java.net and Media Tracker in java.awt. I guess this would be enough from the exam point of view.
Rekha,
The answer is in affirmative. Yes it is imperative for a fresher in Java to undergo this test as it surely does make him grip the essence required which others might not have.
Does this answer help u...
exerpt from java Tutorial
As with static methods and variables (normally called class methods and variables), a static nested class is associated with its enclosing class. And like class methods, a static nested class cannot refer directly to instance variables or methods defined in its enclosing class-it can use them only through an object reference.
As with instance methods and variables, an inner class is associated with an instance of its enclosing class and has direct access to that object's instance variables and methods. Also, because an inner class is associated with an instance, it cannot define any static members itself
Rekha,
It depends how u look at it. This certification as far as i look at it is aimed at making the programmers to make their base strong in Java. And as the passing is 71% it gives an aspirant an all round exposure to the language. He would have to cover all the aspects. What I am trying to tell u is this definitely a Java Certified Programmer is always preferred than a fresher any time as he covers all the aspects of Java needed for programming.
I am sorry if i have not made a point here
Unless the class being declared is abstract, the declarations of all the method members of each direct superinterface must be implemented either by a declaration in this class or by an existing method declaration inherited from the direct superclass, because a class that is not abstract is not permitted to have abstract methods.
as defined in JLS, I guess it gives a very clear picture of what u r looking out for.
CONGRATULATIONS
ABSOLUTELY RIGHT...WHY A CONFUSION??
The following description by JLS suffices the whole Overload fundamentals
8.4.7 Overloading
If two methods of a class (whether both declared in the same class, or both inher-itedby a class, or one declared and one inherited) have the same name but differ-entsignatures, then the method name is said to be overloaded. This fact causes no difficulty and never of itself results in a compile-time error. There is no required relationship between the return types or between the throws clauses of two meth-ods with the same name but different signatures.
Please stick to the syllabus as given by Sun http://suned.sun.com/USA/certification/progobj.html#Java2
Do not believe such unwanted stuffs.
ALL THE VERY BEST FOR THE EXAMS

GC
The answer is
b) After line 8
Some how I feel that this makes the object reference eligible for garbage collection though when it will happen is not possible to note.
