netbeans ?JDK is Java Development Kit. It includes all the Java APIs and Java tools like compiler etc so that you can develop code in Java language.
NetBeans is an IDE (Integrated Development Environment). It provides you tools for helping you write Java code, like it provides you a text editor where you can type your java code etc. You can use any other IDE like Eclipse JCreator etc for writing java code.
NetBeans should come packaged with a JDK. NetBeans requires JDK to function but JDK does not require NetBeans to function.
Personally, if you are so new to the language then I would recommend that you stay away from NetBeans or any other other heavy IDE for a while and code in something like WordPad or some of the other editors recommended in this thread. This will help you learn the language better. You can latter decide on an IDE when you are comfortable with the language.

  • What is the difference between SDK and JDK?

    Which is better? Are they both free for dowload?
    Thanks.
    Virum

    sdk, jdk.. same thing. Whether you call it jdk1.3.1 or j2sdk1.3.1, doesn't matter. It's the standard edition. Free for download.
    There are 3 editions, micro (J2ME), standard (J2SE) and enterprise (J2EE).
    The microedition is when you develop for small devices like smart cards, mobile phones, etc.
    J2SE is what you would most like need, even if you also want to build enterprise applications.
    J2EE is mostly for webservers, where you develop JSP, servlets, EJBs etc.

  • What are the differences between api and sdk

    Hi,
    Could anybody clarify for me what are the difference between API and SDK? I googled for the answer, and couldn't find any thing on this topic.
    Many thanks in advance.
    javasfan

    Is it correct to say that "a SDK includes all the
    APIs"? or "API sits on top of the SDK"?It's a bit weird to say either. First, the JDK doesn't include all APIs. Just the J2SE core API. Others, like 3rd party libraries or J2EE are not included. Second, if you mean the API docs, they're also not included IIRC.
    It'd technically only be correct to say "the SDK provides an API", I guess. The example is very lame, but: if the SDK is a machine, the API is the sum of its buttons and levers and gauges and intakes and outlets and exhausts. The API docs are the manual.

  • What is the difference between #variable_name and :variable_name?

    Hi!
    What is the difference between #variable_name and :variable_name?
    I have found that if we use alphanumeric variable then :variable_name return value in quotes but #variable_name without quotes.
    Why it does not work in the same way for variable default values when variable is used in filter? (It works in mapping)
    I use variable in filter like T.OUT_DATE>convert(datetime,:LAST_UPDATE_DATE,121)
    When I use my variable in package and do refresh it works fine. But when I try to execute the same interface with variable default value I get error. Seems that variable name has been not changed to the value. It does not work with default value in quotes neither without quotes.
    Any ideas how to solve that?
    Thank you in advance!
    Edited by: user13278245 on Sep 15, 2010 4:34 AM

    Question is how to make it work with default value, when I execute interface standalone, not in package? And why it works in mapping but not in filter?
    + I have found that it works if source is Oracle. It doesn't work only for MS SQL source.

  • What is the difference between start() and run()

    Hi:
    what is the difference between start() and the run()???
    in my app, i have
    Console.debug( "starting thread to listen for clients" );
    _server = new Server( this );
    _server.start();
    _server extends Thread..
    why everytime i use server.start(); my app will terminate on it is own, even though in my servr.run() method, i have a while loop
    and if i call _server.run() explicitly in my code, that while loop will be in execution
    can someone let me know??
    thnx

    what is the difference between start() and the
    run()???start() is a method on Thread that tells it to start.
    run() is a method in the object that the thread executes.
    why everytime i use _server.start(); my app will
    terminate on it is own, Err.... I'm not convinced this is true. It'll throw an IllegalThreadStateException, if you try to restart an existing thread.
    If that's what you're saying.
    even though in my _servr.run()
    method, i have a while loopI don't see the connection. Are you saying that the while loop never terminates, and you don't see why the thread is terminating?
    and if i call _server.run() explicitly in my code,
    that while loop will be in executionIf you call server.run() explicitly, then run() will be executed in the same thread that you called it in.

  • What is the difference between exists and in

    hi all
    if i have these queries
    1- select ename from emp where ename in ( select ename from emp where empno=10)
    and
    2- select ename from emp where exists ( select ename from emp where empno=10)
    what is the difference between exists and in is that only when i use in i have to bring the field name or what.... i mean in a complex SQL queries is it will give the same answer
    Thanks

    You get two entirely different result sets that may be the same. Haah! What do I mean by that.
    SQL> select table_name from user_tables;
    TABLE_NAME
    BAR
    FOO
    2 rows selected.
    SQL> select table_name from user_tables where table_name in (select table_name from user_tables where table_name = 'FOO');
    TABLE_NAME
    FOO
    1 row selected.
    SQL> select table_name from user_tables where exists(select table_name from user_tables where table_name = 'FOO');
    TABLE_NAME
    BAR
    FOO
    2 rows selected.So, why is this? the WHERE EXISTS means 'if the next is true', much like where 1=1 being always true and 1=2 being always false. In this case, where exists could be TRUE or FALSE, depending on the subquery.
    WHERE EXISTS can be useful for something like testing if we have data, without actually having to return columns.
    So, if you want to see if an employee exists you might say
    SELECT 1 FROM DUAL WHERE EXISTS( select * from emp where empid = 10);
    If there is a row in emp for empid=10, then you get back 1 from dual;
    This is what I call an 'optimistic' lookup because the WHERE EXISTS ends as soon as there is a hit. It does not care how many - only that at least one exists. It is optimistic because it will continue processing the table lookup until either it hits or reaches the end of the table - for a non-indexed query.

  • What is the difference between TO_CHAR and TO_DATE()?

    Hi everybody,
    i am facing a problem in my system.It is quite urgent, can you explain me "What is the difference between TO_CHAR and TO_DATE()?".
    According to user's requirement, they need to generate a code with format "YYMRRR".
    YY = year of current year
    M = month of current month (IF M >=10 'A' ,M >=11 'B' , M >=10 'C')
    RRR = sequence number
    Example: we have table USER(USER_ID , USER_NAME , USER_CODE)
    EX: SYSDATE = "05-29-2012" MM-DD-YYYY
    IF 10
    ROW USER_ID , USER_NAME , USER_CODE
    1- UID01 , AAAAA , 125001
    2- UID02 , AAAAA , 125002
    10- UID010 , AAAAA , 12A010
    This is the original Script code. But This script runs very well at my Local. Right format. But it just happens wrong format on production.
    12A010 (Right) => 11C010 (Wrong).
    SELECT TO_CHAR(SYSDATE, 'YY') || DECODE( TO_CHAR(SYSDATE, 'MM'),'01','1', '02','2', '03','3', '04','4', '05','5', '06','6', '07','7', '08','8','09','9', '10','A', '11','B', '12','C') ||     NVL(SUBSTR(MAX(USER_CODE), 4, 3), '000') USER_CODE FROM TVC_VSL_SCH                                                       
         WHERE TO_CHAR(SYSDATE,'YY') = SUBSTR(USER_CODE,0,2)                         
         AND TO_CHAR(SYSDATE,'MM') = DECODE(SUBSTR(USER_CODE,3,1),'1','01',          
              '2','02', '3','03', '4','04', '5','05',          
              '6','06', '7','07', '8','08', '9','09',          
              'A','10', 'B','11', 'C','12')

  • What is the difference between upgradation and migration.

    Hi Guru's
    what is the difference between upgradation and migration.
    actuallly i involved in upgradation project, here my role is
    1. first i check the query's in 3.5 save the query and transport the query. and check the query in bex analyzer also.
    2. go to BI .7  find the query;s ,give the query name and save the query ,
    3. once save the query, again will come to 3.5 open the query , it will not open. this is my job here,
        come to 7.0 check the query in analyzer also.
    i am having littile bit confusion, how it will comes query in 7.0, why are u saving the query's in 3.5 and 7.0
    query's already available in 7.0 why are u doing this work?
    can i know the upgrades those  objects, is it neccessary, if necessary how can i upgrade.
    infoobje , transferrules, transferstructure ,infosoure, datasoure,updaterules, ods, cubes.
    Points will be Assingned ,
    Thanks & Regards

    Hi,
    I was talking in a general sense not on a query level.
    If your taling about migration in that level meaning as a part of larger upgradation (in your case 3.x to 7) there may be many places where you need to do this kind of activities.
    Fr eg migration into new data flow, Migration of Web templates from BW 3.x to Netweaver 2004s, etc
    Hope this helps.

    pls tell  briefly

    Hi Kuamr,
    UPLOAD and DOWNLOAD, the function modules used until now are not part of the standard set of ABAP commands. They are used to display the file interface on the presentation server. UPLOAD and DOWNLOAD are not compatible with USs and have been replaced by GUI_UPLOAD and GUI_DOWNLOAD.
    The new function modules, GUI_UPLOAD and GUI_DOWNLOAD, have an interface that also allows you to write Unicode format to the local hard drive. For a description of these interfaces, refer to the documentation for each function module, available under SAP Easy Access " Development " Function Builder " Goto " Documentation.
    Instead of using the function modules, you can use the static methods GUI_UPLOAD and GUI_DOWNLOAD of the global class CL_GUI_FRONTEND_SERVICES.
    Hope this resolves your query.
    Reward all the helpful answers.

    What is the difference between Service and Component?

    Generally, the implementation of a service will be comprised of many components, each of which will be comprised of many objects.
    Services should correspond to cohesive collections of use cases (eg an online bank), components are at a finer granularity (eg a table of numbers).
