What is an annotation?
929348
Annotation is extra information associated with a particular point in a document or other piece of information.\n\nMost commonly this is used for example in draft documents, where another reader has written notes about the quality of a document at a certain point, "in the margin".\n\nAnnotations about bibliographical sources, labeled annotated bibliographies, give descriptions about how each source is useful to an author in constructing a paper or argument. Creating these blurbs, usually a few sentences long, establishes a summary for and expresses the relevance of each source prior to writing.\n\nIn computing, the programmer often adds annotations to source code in the form of comments. These do not affect the working of the program but give explanations (for other programmers, or potential readers of the code principally, but also as a reminder for the author), hints or plans for improvement, etc.\n\nFurther annotations can also be added by a compiler or programmer in the form of metadata, which is then made available in later stages of building or executing a program. For example a compiler may use metadata to make decisions about what warnings to issue, or a linker can use metadata to connect multiple object files into a single executable. Differences in computer languages have given rise to a variety of words for programmer-added metadata, including annotation (Java), attribute (C#), pragma (C), and metadata (HTML).\n\nAnnotations in particular domains\n\nBiology\nMolecular biology and bioinformatics have known the need for DNA annotation since the 1980s, where a previously unknown sequence representation of genetic material is annotated with information relating position to intron-exon-boundaries, regulatory sequences, repeats, gene names and protein products, etc.. This annotation is usually stored in predefined fields in biological databases, especially sequence databases. There are a number of very active genomic and proteomic annotation projects today, including Mouse Genome Informatics, FlyBase, and WormBase. Educational materials on some aspects of biological annotation from this year's Gene Ontology annotation camp and similar events are available [here].\n\nImaging\nIn the digital imaging community the term annotation is commonly used for visible metadata superimposed on an image without changing the underlying raster image, such as sticky notes, virtual laser pointers, circles, arrows, and black-outs (cf. redaction).\n\nLinguistics\nIn linguistics, morphological, syntactic, semantic, discourse and pragmatic annotations add information about the linguistic form. Other forms of annotation include comments and metadata; these non-transcriptional annotations are also non-linguistic. A collection of texts with linguistic annotations is known as a corpus (plural corpora).

A cursor is a moving marker or pointer that indicates a position. English-speakers have used the term with this meaning since the 16th century, for a wide variety of movable or mobile position-markers.\n\nThe literal meaning of the original Latin word cursor expresses the idea of someone or something that runs.\n\nQUICK GUIDE TO USING EXPLICIT CURSORS WITHIN SQL*FORMS 3.0 \n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ \n\nMany users perceive Explicit Cursors as a difficult means of retrieving \ndata from the database. In reality, only a few basic concepts are needed \nto implement this flexible method, thus, maximizing efficiency and \ndeveloper control. \n\nA cursor is a named SQL statement. From the PL/SQL User's Guide and \nReference Manual (Page 2-16): \n\nWhen a query returns multiple rows, you can explicitly define a cursor to: \n\n* process beyond the first row returned by the query \n* keep track of which row is currently being processed. \n\nCursors allow the designer precise control of the multiple values returned \nby the cursor's SELECT statement. \n\nNote that explicit cursors should be used in specific cases only. For most \napplications, the default database block is sufficient and easier to use \nthan explicit cursors. Please read the last section of this document for \nsituations where explicit cursors may be appropriate. \n\nPOPULATING MULTI-RECORD BLOCKS \n~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ \nExplicit cursors can be used to query records into a block, similar to \na normal EXECUTE_QUERY within a database block. The basic difference \nbetween these two methods is that each record queried into the block \nis tied, by rowid, to a row in the database. An explicit cursor \nretrieves the data and places it into a field as if a user had input \nthe data by hand. A more in depth discussion of the differences is \nincluded in the last section of this bulletin. \n\nBelow is a simple example of populating a multi-record block using \nexplicit cursors. To recreate this you will need to use the standard \ndatabase tables that are supplied with SQL*Forms: create a non-base table \nblock F_EMP, with 3 fields F_EMPNO, F_ENAME and F_DEPTNO that have the same \ndatatypes and field lengths as the standard EMP fields EMPNO, ENAME and \nDEPTNO in the database. \n\nKEY-HELP \n\ndeclare cursor C1 is select EMPNO,ENAME,DEPTNO \nfrom EMP \nwhere DEPTNO>10; \nbegin \ngo_block('F_EMP'); /* This isn't necessary if you are already in \nthe block where the values are being entered */ \nopen C1; \nloop \nfetch C1 into :F_EMP.F_EMPNO, :F_EMP.F_ENAME, :F_EMP.F_DEPTNO; \nexit when C1%notfound; \nnext_record; \nend loop; \nclose C1; \nfirst_record; \nend; \n\nNote the looping structure. The FETCH, grabs the next (or first) row from \nthe table satisfying the cursor declaration, INTO the specified fields. If \nit is not the last record, then the cursor is moved to the next record and \nthe next FETCH INTO is performed. After the cursor is closed, the cursor \nis put on the first record of the block, the same functionality as a \nregular database block query. \n\nAvailable cursor options are \n\n%NOTFOUND : TRUE if fetch failed because no more rows were available. \n%FOUND : Logical opposite of %NOTFOUND. \n%ROWCOUNT : Returns the number of rows fetched from the active set so far. \n%ISOPEN : TRUE if explicit cursor is open. \n\nfor more details -\n\nhttp://experts.about.com/q/Oracle-1451/use-cursor.htm

It's a design pattern that separates presentation (view) from business objects (model).  The part that "orchestrates" the interaction between presentation and business is called the "controller".  Struts and JSF both use this pattern along with many other frameworks.

* Denotation refers to the literal meaning of a word, the "dictionary definition."¨ For example, if you look up the word snake in a dictionary, you will discover that one of its denotative meanings is "any of numerous scaly, legless, sometimes venomous reptiles¡having a long, tapering, cylindrical body and found in most tropical and temperate regions."\n    * Connotation, on the other hand, refers to the associations that are connected to a certain word or the emotional suggestions related to that word. The connotative meanings of a word exist together with the denotative meanings. The connotations for the word snake could include evil or danger.\n\nExamples:  While "necktie" and "cravat" have the same denotation, they have quite different connotations. "Cravat" carries an added implication of wealth or snootiness.\n\nAlso consider "red." It denotes a particular colour, but also has connotations of irritation or anger in certain contexts.

In Java, "dynamically" is the *only* way to create\nan instance of a class (since unlike C++, it does\nnot allow static or stack-based objects).  Sample\nsyntax is:\n\n    Rectangle rectOne = new Rectangle(originOne, 100, 200);

What is this referring to? Can you post a clarification?

An interface is a collection of method signatures that are defined. Objects can indicate that they implement an interface -- this means they agree to provide the methods that appear in the interface.\n\nFor example, perhaps I have an interface called Printable that contains a single method print. Note the interface has no actual code for this method, just the signature (name, return type, argument list, etc.).\n\nThen if an object implements Printable, it is promising to provide a print method with the right signature.\n\nNow, any piece of code can get a reference to the object and treat it as though it were a "Printable" object -- there isn't any such class, but in this context, the interface is like a class.\n\nThis allows you to create lots of class hierarchies with different roots, but use any object as "printable".\n\nNote that some interfaces have no methods at all -- just the fact that they implement an empty interface indicates something about the object.

I'm not sure, but you might be referring to a code section of an HTML blog that basically serves as a tag that starts/stops particular blog entries.\n\nI tried looking this up and found nothing.  One of these internet gurus should hopefully help.\n\nGood luck.  Sorry, but I tried !   ;-)

I love netbeans, it has anumber of built in features that aide in app development. Code completion, cvs, refactoring,etc... You may also want to check out eclipse and Sun Studio.  I know  for sure sun studio also adds a UML editor which is pretty clever since it also allows you to generate java code from the UML diagrams

It is a concept of computer science, not java only\nIn a more modern computer science context serialization is the process of saving an object onto a storage medium (such as a file, or a memory buffer) or to transmit it across a network connection link such as a socket either as a series of bytes or in some human-readable format such as XML. The series of bytes or the format can be used to re-create an object that is identical in its internal state to the original object (actually a clone). This type of serialization is used mostly to transport an object across a network, to persist objects to a file or database, or to distribute identical objects to several applications or locations.\n\nThis process of serializing an object is also known as deflating an object or marshalling an object. \nThe opposite operation, extracting a data structure from a series of bytes, is deserialization (which is also referred to as unmarshalling or inflating).
