what is adapter in JAVA?
140748
Generally speaking, an adapter is the "glue" that\nbridges between incompatible interfaces.  In Java,\nthis would be a class which "wraps" another in order\nto make it compatible for some other use.\n\nThe description in reference [1] is:\n "Convert the interface of a class into another interface\n  clients expect. Adapter lets classes work together that\n  could not otherwise because of incompatible interfaces.\n\nA further explanation, and example, is given in [2].\n\nThere's a very handy implementation trick for\nadaptors where an an entire interface is implemented\nwith "dummy" methods.  This "dummy" class can then\neasily be subclassed, but only those methods which are\nneeded must be implemented.  This saves the user\nfrom having to fill out the entire interface.\nSee reference [3] for a more complete description\nand what I expect is one of the most common examples\nof when adapters are used.

System.out is indeed an instance of java.io.PrintStream.  println() is a member function of java.io.PrintStream, but you're calling println() you're actually working with java.lang.System.out (which is a PrintStream, but Java already knows that, so you don't need to import PrintStream to show it).  \n\nPerhaps it would be helpful to you to understand what Java actually does with import statements.  They are *not* used to give the program access to different pieces of code.  It is tempting (especially for C/C++ programmers) to think that import statements are a mechanism for including other code files, but they are really more like C++ "using namespace" statements.  Java import statements have exactly one function: to save you typing.  You can take any program and remove all the import statements without breaking it, so long as you're willing to use the full names of all of your classes.\n\nJava's technique for deciding which files it needs to use is rather interesting.  Since all public classes are in files of the same name, Java can easily find any class by looking for a file named "name.java" (or name.class if compiled).  The dots between the package names are used to separate directories.\n\nOf course, if you wanted to pass something System.out as an argument, you'd need to use java.io.PrintStream as the parameter type (or import java.io.PrintStream).

well to say..let me try to explain..\nfirst of we shall go with DataAdapter:\nDataAdapter lets u connect to the database with watever connecting string uve made n the command string that uve made...n gets the data from the database and stores this data in the DATASET.\nDataSEt is used to store the data fetched up by the DataADapter.\nWhereeas Databinding refers to binding the data, in whatever mode we require. This is mostly used when we've got to retrieve the data from many tables and shoe in the datagrid.\nMy code for the above goes like this:\n//This is to show the 'EMP' table details existing in the Oracle, using OLEDB Provider....shows the entire table details, after clicing the button1_click event...\n\nbutton1_click(..)\n{\nstrign strcon="provider=MSDAORA.1;User Id=scott;Password=tiger";\nstring strcom="select * from emp";\nOleDbDataAdapter adapter=new OleDbDataAdapter(strcom,strcon);\nDataSet dataset=new DataSet();\nadapter.Fill(dataset,"emp");\ndataGrid1.DataSource=dataset.Tables["emp"}.DefaultView;\n}\n\nThis may have some minor errors..please check out them\nHope u got what ive tryed to explain...

A data adapter has to be set up to actually update data. You need to either use a CommandBuilder and give the DataAdapter its GetUpdateCommand() method to its .UpdateCommand property, or you have to write the SQL for the UpdateCommand yourself.\n\nThe fact that it is not saving for you either way should be your clue that the problem is with your saving procedure, and not the exit event.

A collection in any language is a container that will hold other objects.  Examples of container classes in Java are List, Map, Set.  These are actually implemented as interfaces, they just define the basic methods that are expected for each of the different types of collections.  Concrete implementations for each of these interfaces would be HashSet, ArrayList, LinkedList, HashMap, TreeMap, TreeSet (there are others, but these are the most popular).\n\nThe simple answer to your question in regards to whether an interface and a class are the same is NO.  An interface is a definition of methods.  A class is an implemetation of those and probably other methods.  The syntax for this in Java would look like:\n\nclass X implements Y\n\nWhere X is the implemetation of the Y interface.  That is exactly how the collection classes are implemented in the JDK, the class declaration for ArrayList follows:\n\npublic class ArrayList<E> extends AbstractList<E>\n        implements List<E>, RandomAccess, Cloneable, java.io.Serializable\n\nNow, keep in mind that you CAN use an interface to access an instance of a class (an object).  For example:\n\nList myList = new ArrayList();\n\nList is an interface, ArrayList is a class.  Actually this is the intention of interfaces, separation of model and implementation. You could use a LinkedList in your code if you wrote your code this way just by changing the line that declares myList and no other code would have to be touched:\n\nList myList = new LinkedList();

Better way is to creat an instance of Random class.\nIt has methods, nextInteger(), nextdouble(), and others.

Oucchhh...Sory you had to go through that. I had almost a There are a couple of ways to find out the name/part number of the adapter you are looking for. You could call the manufacturer and ask for the name of that part and then look for that part on the internet. You could also try looking on Ebay by searching for ads about your model. You could do a search on a how-to on your model. Hope this helps.

You can execute the system call of dir and pipe output to a file/string/strings and then do a search or pattern match on that.\n\nRemember u need not make system call, but this following code compiles to sufficient commands in Java class file, and JVM runtime machine will execute that instructions and makes system calls depending on OS and Environment, on behalf of user and returs the results to the hash/buffer/stack area of JVM used by that class-file/code under running. And other important thing is that there is no eazy and free way for pattern match. You might want to write your own patten matching if it were simple patterns.\n\n\nhttp://javaalmanac.com/egs/java.io/GetFiles.html?l=rel\n\n\nFor using Java's Pattern matching, u might want to do this. But for your case of searching executables, just compare last 4 characters and if it matches ".exe" then u r good to go.\n\nhttp://java.sun.com/j2se/1.4.2/docs/api/java/util/regex/Pattern.html

I'm not exactly sure what you mean?\n\nAre you trying to run a Java application and the main method can not be found?\n\nIs there a specific error message you are seeing that you can add to the details of this question?

java usees wrapper classes...Byte,Integer..they are in java.lang package..\n\nin each such class there is one memeber \nstatic int SIZE\n\nusing that u can find out..\n\neg.System.out.println(Byte.SIZE);\n//The number of bits used to represent a byte value in two's complement binary form\n\nSIMILARITY FOR OTHER DATA TYPES..\n\ncheck out documentation site..or if u have already downloaded doc..then use that..

The most likely problem is that the applet was written using an API with methods that don't exist in the JVM class API being used by IE.  Update your browser Java Plugin to the latest and then try.

There really isn't anything that I know of that u can do in java, but try not having the scripts embedded. It sounds like the computer can't handle so much info.
