Vector, what is the problem with this code?

Vector, what is the problem with this code?
63 private java.util.Vector data=new Vector();
64 Vector aaaaa=new Vector();
65   data.addElement(aaaaa);
74 aaaaa.addElement(new String("Mary"));on compiling this code, the error is

                    ^
TableDemo.java:74: package aaaaa does not exist
                aaaaa.addElement(new String("Mary"));Friends i really got fed up with this code for more than half an hour.could anybody spot the problem?

I can see many:
1. i assume your code snip is inside a method. a local variable can not be declare private.
2. if you didn't import java.util.* on top then you need to prefix package on All occurance of Vector.
3. String in java are constant and has literal syntax. "Mary" is sufficient in most of the time, unless you purposly want to call new String("Mary") on purpose. Read java.lang.String javadoc.
Here is a sample that would compile...:
public class QuickMain {
     public static void main(String[] args) {
          java.util.Vector data=new java.util.Vector();
          java.util.Vector aaaaa=new java.util.Vector();
          data.addElement(aaaaa);
          aaaaa.addElement(new String("Mary"));
}

What's the point of this code?

Hi, I'm getting an error in a program.
So I went to look in the code where the error is displayed.
And I found this:
z_nbjr = sy-datum - z_fromdt.
if z_nbjr > 1.
message is displayed.
Now, z_fromdt is the value TVARV-LOW for 'ZVDL_VBUK_LAST_RUN', and the message that is displayed is 'Please rebuild index file ZVDL_VBUK'.
Can anyone explain to me what is the point of this? What is TVARV-LOW?
And why do they make this check? And how do I rebuild the index file?

As Pushpraj has already pointed out correctly, TVARV is where the variants are stored. It's rather strange that you've never seen fields like LOW and HIGH, because they're also used in the ABAP range tables (see Help for command RANGES).
Since this is all your custom development, we, unfortunately, cannot know what is the point of all this. I'm guessing that the message to "rebuild the index" is also custom and, therefore, you would need to find a documentation for the program in question or ask your colleagues what this could mean. Also check if there is a long text available for the message (although I doubt that).
Most likely it's some kind of an internal process of running some other program.

What is the wrong with this small code of groupitems

1.GUIFrame frame = new GUIFrame("Formula One Manager");
2.GUIFrame frame = new GUIFrame("Formula One Manager");
3.g.DrawImage(img1, 0, 0, this);
the line underneath the error code is what is given with the IDE iam using (Gel)
The idea of this little code is to get a picture up for my game
Can anybody help

I get 3 errors
1.GUIFrame frame = new GUIFrame("Formula One
Manager");
2.GUIFrame frame = new GUIFrame("Formula One
Manager");
The two are probably related. The code is looking to create
an instance of the class GUIFrame. The compiler won't see
GUIFrame unless you either import it into your source file with
import <<whatever>>.GUIFrame, or have the GUIFrame class within
the same package as your new class.
In addition, you'll also need to make sure that the GUIFrame class
contains a Constructor that takes a single String parameter, or you'll
get an error with that line.
3.g.DrawImage(img1, 0, 0, this);
------------------------------it's g.drawImage, not g.DrawImage

Please help me: what is the wrong in my code?

Hi all ,

but i didn't receive any mail.can any one please help in resolving my prob :((

When using Runtime.exec(String) method, the parameter is split by whitespaces. The first token being the program to run, and each other being considerred as an argument to this program.
In your test, the body contains whitespaces. Therefore, "This" is considered as one argument, and "is" as another one (mail list in this case...), etc.
You should consider using the Runtime.exec(String[]) method instead, whith which you have control on the parameters (the first element of the array being the command and every subsequent element being an argument.)String[] exec_command = {"send_mail.ksh", subject, body, mailIds};
Process p = Runtime.getRuntime().exec(exec_command);http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Runtime.html

hi rakesh,
    in your first select single * statement you have given WHERE BUKRS = T001K-BUKRS..but at the point of execution, what will be the value stored in t001k-bukrs...i doubt it will be initial....so, store bukrs in a variable or hardcode it.....
   in the second select, you hve not given any target work area for the into class...that's y your subrc is 4...specify a target area, where you want the data to be stored...

What is the problem with this code ? Race condition??

Guys,
The idea behind the attached code is quite simple.
I have a 2D parent array. First, I print a subset of this array into a table control (based on a sensor selection). Now, I want edit the numbers in the table. I need the changes to be reflected in the table and the parent 2D array. (In simple terms, this is like replacing the the edited array subset into the parent 2D array)
The problem is when I change(edit) any entry in the table, the entry changes back to its original value. The change doesnt seem to be reflecting on the parent 2D array and the table. .
Can anyone tell me where the problem is?
Thanks
Ravi

I agree with Chris, here's an idea (of whatI think your code does):
The case structure in your code was unnecessary, all the cases were the same so I removed them.
The sequence structure was unnecessary.

What is the problem with this code?

dear sirs...
i have a page that does not contain any binding, it contains the following event:
public void onCheck(DataActionContext ctx)
ViewObject V=ctx.getBindingContext.findDataControl("AppModuleDataControl").getApplicationModule.findViewObject("empview1");
V.setWhereClause("");
V.executeQuery();
V.first();
note that the above code works if the table emp is on the page, however, if the page is not bound to the page (it does not contains the table) the statement in the bold will fire an exception saying that there is no binding. i am sure the V is not set to null.
another problem appears, if i put the table and execute it within jdeveloper, it works correctly, however, if i run if i deploy the application into application server, the code never runs as if there is some kind of an error.
i hope that you can anser me about the following;
1- if the code above correct?
2- how can i view the log for the application?
3- System.out.println("test"); in jdeveloper works okay, in the application server, does it cause some kind of an error?
thanks for any help & best regards

If you don't close the ResultSet, different things happen based on which database you're running. You can keep read locks that you don't need. It wastes resources, and as different databases react differently to it, you might have weird bugs down the road that result from your practices of not properly closing ResultSets, PreparedStatements, and Connections. Put this in a loop like you've got here, and the effects may or may not get amplified.
I write a close() for a ResultSet just as soon as I open it, just to make sure I don't forget. In a situation like this one, I would write something like so:
for(int i = 0;i<someValue;i++)
try
//some code
rs = pstmt.executeQuery();
//some code that uses rs
catch(Exception e)
finally
if (rs != null)
rs.close();
if (pstmt != null)
pstmt.close();
}

Can any one tell what is the problem in this code?

The problem am facing here is that when i minimize the frame and maximize , my old lines are getting disappared.
For avoiding that i am storing the old coordinates and
try to redraw , when maximize.
but the lines are coming for flash of second and disappearing once again ?
can any one help?
thanks all

Very interestingly the same code is repainting in
Linux SUSE,jdk1.3.
but not in WINNT , jdk 1.3
Any reason ?
Is the swing 100 % platform independenet ?????
Does swing also uses native thread ???

What is the wrong in this code
