Is it an error in documentation?

Hi all, I'm not so new to Java, but today I stuck with problem below:
I've found at http://java.sun.com/docs/codeconv/html/CodeConventions.doc9.html
the example of ++ operations usage which has following operator:
if ((c++ = d++) != 0) {
which doesn't compile.
I thought it's compatible with one of old Java versions but I failed to find the way to get it work.
Is it an error in the article or I missed something?
Thanks.

It's an error. I assume they meant
if ((c++ == d++) != 0)EDIT: No, that doesn't work either.
Okay, I don't know what they meant.
Maybe
if ((c = d++) != 0)Meh. Whatever.

(Error in documentation?) Math operator precedence problem

Hello,
I apologize in advance, while I do know programming (I'm a PHP and Perl programmer) I'm fairly new to Java so this may well be a silly question, but that's why I am here. I hope you'll show me where my error is so I can finally set this to rest before it drives me mad :)
(Also, I hope I'm posting this in the right forum?)
So, I am taking a Java class, and the question in the homework related to operand precendence. When dealing with multiplication, division and addition, things were fine, the documentation is clear and it also makes sense math-wise (multiplication comes before addition, etc etc).
However, we got this exercise to solve:
If u=2, v=3, w=5, x=7 and y=11, find the value assuming int variables:
u++ / v+u++ *w
Now, according to the operator precedence table (http://docs.oracle.com/javase/tutorial/java/nutsandbolts/operators.html) the unary operator u++ comes first, before multiplication, division and addition.
This would mean I could rewrite the exercise as:
((u+1)/v) + ((u+1)*w) = (3/3) + (4*5) = 1+20 = 21
However, if I run this in Java, the result I get is 15.
I tried breaking up the result for the two values in the Java code, so I could see where the problem is with my calculation.
For
System.out.println(u++ /v);
I get 0
For
System.out.println("u++ *w");
I get 15
My professor suggested I attempt to change the values from int to float, so I can see if the division came out to be something illogical. I did so, and now I get:
For
System.out.println(u++ /v);
I get 0.66667
For
System.out.println("u++ *w");
I get 15.0000
Which means that for the first operation (the division) the division happens on 2/3 (which is 0.6667) and only afterwards the u value is increased. That is, the u++ operation is done after the division, not before. The same happens with the multiplication; when that is carried out, the value of u is now 3 (after it was raised by one in the previous operation) and the first to be carried out is the multiplication (3*5=15) and only then the u++.
That is entirely against the documentation.
This is the script I wrote to test the issue:
public class MathTest {
     public static void main (String [] args) {
          float u=2, v=3, w=5, x=7, y=11;
          System.out.println("Initial value for 'u': " + u);
          float tmp1 = u++ /v;
          System.out.println("u++ /v = " + tmp1);
          System.out.println("First ++ value for 'u': " + u);
          float tmp2 = u++ *w;
          System.out.println("u++ *w= " + tmp2);
          System.out.println("Second ++ value for 'u': " + u);
          System.out.println(tmp1+tmp2);
The output:
Initial value for 'u': 2.0
u++ /v = 1.0
First ++ value for 'u': 3.0
u++ *w= 20.0
Second ++ value for 'u': 4.0
21.0
Clearly, the ++ operation is done after the division and after the multiplication.
Am I missing something here? Is the documentation wrong, or have I missed something obvious? This is driving me crazy!
Thanks in advance,
Mori

The fact that u++ is evaluated but in the calculation itself the "previously stored" value of u is used is completely confusing.

Yes it can be confusing - and no one is claiming otherwise. Here are some more thread links from other users about the same issue.
Re: Code Behavior is different in C and Java.
Re: diffcult to understand expression computaion having operator such as i++
Operator Precedence for Increment Operator
>
So, when they explain that ++ has a higher precedence, the natural thing to consider is that you "do that first" and then do the rest.
>
And, as you have discovered, that would be wrong and, to a large degree, is the nut of the issue.
What you just said illustrates the difference between 'precedence' and 'evaluation order'. Precedence determines which operators are evaluated first. Evaluation order determines the order that the 'operands' of those operators are evaluated. Those are two different, but related, things.
See Chapter 15 Expressions
>
This chapter specifies the meanings of expressions and the rules for their evaluation.
>
Sections in the chapter specify the requirements - note the word 'guarantees' in the quoted text - see 15.7.1
Also read carefully section 15.7.2
>
15.7. Evaluation Order
The Java programming language guarantees that the operands of operators appear to be evaluated in a specific evaluation order, namely, from left to right.
15.7.1. Evaluate Left-Hand Operand First
The left-hand operand of a binary operator appears to be fully evaluated before any part of the right-hand operand is evaluated.
If the operator is a compound-assignment operator (§15.26.2), then evaluation of
the left-hand operand includes both remembering the variable that the left-hand
operand denotes and fetching and saving that variable's value for use in the implied
binary operation.
15.7.2. Evaluate Operands before Operation
The Java programming language guarantees that every operand of an operator (except the conditional operators &&, ||, and ? appears to be fully evaluated before any part of the operation itself is performed.
15.7.3. Evaluation Respects Parentheses and Precedence
The Java programming language respects the order of evaluation indicated explicitly by parentheses and implicitly by operator precedence.
>
So when there are multiple operators in an expression 'precedence' determines which is evaluated first. And, the chart in your link shows 'postfix' is at the top of the list.
But, as the quote from the java language spec shows, the result of 'postfix' is the ORIGINAL value before incrementation. If it makes it easier for then consider that this 'original' value is saved on the stack or a temp variable for use in the calculation for that operand.
Then the evalution order determines how the calculation proceeds.
It may help to look at a different, simpler, but still confusing example. What should the value of 'test' be in this example?
i = 0;
test = i++; The value of 'test' will be zero. The value of i++ is the 'original' value before incrementing and that 'original' value is assigned to 'test'.
At the risk of further confusion here are the actual JVM instructions executed for your example. I just used
javap -c -l Test1to disassemble this. I manually added the actual source code so you can try to follow this
        int u = 2;
   4:iconst_2
   5:istore 5
        int v = 3;
   7:iconst_3
   8:istore          6
        int w = 5;
10:iconst_5
11:istore          7
        int z;
        z = z = u++ / v + u++ * w;
   13: iload   5
   15: iinc    5, 1
   18: iload   6
   20: idiv
   21: iload   5
   23: iinc    5, 1
   26: iload   7
   28: imul
   29: iadd
   30: dup
   31: istore 8
   33: istore 8The Java Virtual Machine Specification has all of the JVM instructions and what they do.
http://docs.oracle.com/javase/specs/jvms/se7/jvms7.pdf
Your assignment to z and formula starts with line 13: above
13: iload 5 - 'Load int from local variable' page 466
15: iinc 5, 1 - 'Increment local variable by constant' page 465
18: iload 6 - another load
20: idiv - do the division page
21: iload 5 - load variable 5 again
23: iinc 5, 1 - inc variable 5 again
26: iload 7 - load variable 7
28: imul - do the multiply
29: iadd - do the addition
30: dup - duplicate the top stack value and put it on the stack
31: istore 8 - store the duplicated top stack value
33: istore 8 - store the original top stack value
Note the description of 'iload'
>
The value of the local variable at index
is pushed onto the operand stack.
>
IMPORTANT - now note the description of 'iinc'
>
The value const is first sign-extended to an int, and then
the local variable at index is incremented by that amount.
>
The 'iload' loads the ORIGINAL value of the variable and saves it on the stack.
Then the 'iinc' increments the VARIABLE value - it DOES NOT increment the ORIGINAL value which is now on the stack.
Now note the description of 'idiv'
>
The values are popped
from the operand stack. The int result is the value of the Java
programming language expression value1 / value2. The result is
pushed onto the operand stack.
>
The two values on the stack include the ORIGINAL value of the variable - not the incremented value.
The above three instructions explain the result you are seeing. For postfix the value is loaded onto the stack and then the variable itself (not the loaded original value) is incremented.
Then you can see what this line does
21: iload   5 - load variable 5 againIt loads the variable again. This IS the incremented value. It was incremented by the 'iinc' on line 15 that I discussed above.
Sorry to get so detailed but this question seems to come up a lot and maybe now you have enough information and doc links to explore this to any level of detail that you want.

Error level documentation for 36xx errros

Hi,
Can anyone point me at the documentation for the Error messages for these errors for Sybase 15.x
3606, 3607, 3619, 3620, 3622
Looking in ...
Exception Handling Errors (3600s)
but they seems to be missing.
I can see them in the 12.x manual but I think the severities have changed.
Just wanting to confirm.

Thanks - is any of this docmented anywhere that a developer can read it ?
Since its changed since V12 it might be useful to update the manual.
Its also a little confusing and inconsistent in that sysmessages shows the errors as severity 10.
       select severity from master..sysmessages where error = 3607
but the errors are shown as
       Msg 3607, Level 16, State 0
       Server 'S1', Line 1
       Divide by zero occurred.

Are javac error messages documented with comprehensive explanations

Hi all:
Are the error messages which javac produces documented?
Can anyone recommend a source which explains exactly what the message is trying to tell the beginner?
Often the meaning of the message is clear. But frequently one looks at the message and wonders exactly what the compiler is trying to tell you and how to go about fixing it.
By the way, I am using JDK 1.3.1. I did try searching the forum because I am sure this question has been asked but I couldn't phrase the query so that it gave a reasonable number of items to look at.
Thanks all
Bill

One good tutorial on the meaning of the the various common javac error messages can be found here: http://mindprod.com/errormessages.html
Roedy's stuff is usually quite accurate and reasonably up to date. You might also want to peek around the rest of his Java Glossary - it's got a lot of great info.

Hi Salman and ashahide,
thanks for your answers.
I've changed the syntax like this:
execute DBMS_SCHEDULER.CREATE_SCHEDULE(repeat_interval => 'FREQ=DAILY;BYHOUR=10;BYMINUTE=30'', start_date => to_timestamp_tz('2013-03-11 Europe/Berlin', 'YYYY-MM-DD TZR'), schedule_name => 'FULLBACKUP_DAILY');
But now im getting a new error:

EDIT: I'm sorry for spaming. I'm so blind: 'FREQ=DAILY;BYHOUR=10;BYMINUTE=30'' => there is just one ' to much. Now it works! Thanks a lot for help!

80 GB Video Ipod I/O Error - Well documented

Hello all, I have tried everything to fix this problem and am looking for any input before I mail it off to the great shredder in the sky. I bought my IPod in February 07, and my warranty has ran out. The main issue before you is that _My IPod can play music, but I cannot update the music or access files on the IPod’s HD via my PC._ I am using a HP Pavilion dv6000 laptop computer.
This whole mumbo-jumbo began about two weeks ago when I received a low battery error. After plugging into a wall socket and letting sit overnight, the batteries had barely even charged.
Whenever my IPod plugs in, it lights up, "Do not disconnect" still appears. The iPod appears in the device manager but no drive is assigned to it. When I open iTunes, the IPod will not appear in the menu to the left.
After about 15-20 minutes, the IPod will be assigned a drive (in my case G), and appear as a drive in the device manager, and appears in My Computer. (http://s177.photobucket.com/albums/w214/halofan007/?action=view&current=MyComput er.jpg ) But whenever I attempt to access the IPod, I receive the following message: _“G:\ is not accessible. The request could not be performed because of an I/O device error.”_ (http://s177.photobucket.com/albums/w214/halofan007/?action=view&current=Error.jp g)
So, here is what troubleshooting I have done in response.
Physical trouble shooting:
Other USB devices function well from the port, and I have attempted to use the IPod from all the possible USB ports on my laptop. Yesterday I bought (from a Mac store) a brand new USB 2.0 IPod cable. I have reset the IPod over 10 times. I have let the IPod die, and then recharge, (meh, didn’t do much, worked once in the past!). Other friend’s IPods plug in with no issue to my laptop. My computer has been restarted hundreds of times.
Web/Software troubleshooting:
I have followed the entire instructions on the iPod missing in "My Computer" or in iTunes for Windows but I will detail what I have done so I won’t be bogged down by “Have you done __?” I used the 5 R’s from the apple website: The 5 R's Assistant minus the restore function (which would be great if my IPod could be detected!). I restarted my computer, updated iTunes, used windows update. In another attempt regarding “Applying to Device Manager malfunctions after you install Windows XP Service Pack 2” at http://support.microsoft.com/default.aspx?scid=kb;en-us;893249 I have had Windows XP Service Pack 2 for almost a year already installed with no IPod/USB Issues before now. I have updated my drivers for my USB ports. (http://s177.photobucket.com/albums/w214/halofan007/?action=view&current=SP2.jpg )I followed the instructions Laptop or portable connecting via USB? And disabled the power saving functions for my USB ports. (http://s177.photobucket.com/albums/w214/halofan007/?action=view&current=Powersav e.jpg ) Yes I have completed the rest of the suggestions on this page before posting.
I then went on to the list from iPod shows up in Windows but not in iTunes , hoping that it would fix it. I attempted to fix registry keys detailed on this Microsoft page: http://support.microsoft.com/kb/925196 . These keys were not there. Next I deleted my local temp folder in local settings as suggested by http://support.microsoft.com/kb/925196 . No dice. Again, yes, I have completed the rest of the suggestions on this page before posting.
So, any more suggestions before I attempt to have it serviced? Bang it against a wall? Drive over it? Any useful insight would be greatly appreciated.
P.S. “If this issue has been addressed in another thread, Bull@$%@ because I have searched this forum like no other, but if it has, please link to it.”
P.S.S (Don’t hate on me for using paint!)

The delay in your ipod showing up in Device Manager would indicate a drive collision with another device on your computer. Connect your iPod to your laptop and disconnect all other USB devices, PC cards, and disconnect from any network you might be on and then set another drive letter for your iPod. Try M or P or Z: http://docs.info.apple.com/article.html?artnum=93499
If this doesn't work, as PP said you are still in warranty, only your free phone support has lapsed. If your purchase AppleCare for this laptop you could extend free phone support, and your warranty, to February 2009.

Error in documentation?

Hello,
I'm reading the "Packaging Extensions with Adobe Extension Manager CS5" pdf. Page 18, about the <product> tag it says:
maxversion - Specifies the latest product version that an extension can be installed in. For example, if a Dreamweaver extension can be installed with CS5 only, you would specify <product name="Dreamweaver" version="11" maxversion="11"/>
Maybe I'm wrong, but isn't 12, the CS5 version? So, shouldn't read:
maxversion - Specifies the latest product version that an extension can be installed in. For example, if a Dreamweaver extension can be installed with CS5 only, you would specify <product name="Dreamweaver" version="12" maxversion="12"/>
Thanks,
Davide

The version of DreamWeaver CS5 is 11. The version numbers of Adobe products are summarized in table at page 16-17. Only version of Photoshop CS5 is 12.

BW Authorization Error documentation Question

Hi,
I have a question, may be you can help in this:
Q: In BW Analyzer if we get the following authorization error for some reason:
->Authorization Check
You do not have authorization for Add or Create
There is a Details tab to see the authorization error details. I need to add documentation for the naming conventions the Users need to use so that it's easy for Users to see what is the reason for the error and what naming convention do they need to use to prevent the error.
Right now, details tab shows "No Documentation Available". How can I add documentation here? Where do I add this documentation and how do I link it to the Authorization Error Message's Details tab?
I tried running RSRTRACE to see which function modules/programs get called but that does not help. It gives me the following two function modules which are being called when I get the error message and when I click the details tab:
RZX0_MESSAGES_GET
RZX0_MESSAGE_H_GET
and surprisingly when I try to look them up in SE37 they do not exist What can be the reason for this?
Is there a system transaction, like .. SM02, in BW where we can define or create authorization error message documentation for BEx Analyzer? How do I link it to the Authorization Error message?
Your help or advise will be very much appreciated.
Thank You,
Regards,
Mandeep Virk

It can be done via SE91.
Message Class is R9 and message number is 108
We have to define the Long Text and save it under the RSZ class.
It works for me now.

==============
Was the CKPT Termination caused by some error in Redo Logs which needed recovery?

Lookup the Error messages documentation.
Error 472 is
"PMON process terminated with error "
CKPT detected that PMON had "died" and so it forcibly terminated the database instance. (The background processes monitor each other and are designed to terminate the database instance if a critical process dies).
Look for a trace file.
PMON died because of a resource issue or a bug or a server issue or because it was killed (by the OS or a user or process with oracle / administrator privileges)

Error while creating Info Package

Hi,
I am new to SAP-BW .Could anyone help me in fixing the following error .
I have created an Info source for characteristic data and then trying to create a Infopackage to load master data , I have used the characteristic Material Number(IO-MAT) in this case .
When creating the Info Package I got two data sources in the pop up , Material number (Master data)IO_MAT_ATTR and Material number (Texts) IO_MAT_TEXT .
I was able to load data from a flat file into Data Source Material Number (Master data) But when I was trying to follow the same procedure and load the data for 'Material number(Texts) IO_MAT_TEXT' it gives me the following error .
Select the Language field in the source system -> Long Text
I am not able to figure out and proceed further. Pls help me out.
Regards
Sudha

I have another question..I was able to fix the error regarding info package but unable to load the data..(data load is being failed)
In the DataSource/Transfer Structure I have LANGU , /BIC/ZB4_MAT (Material Number infoobject which i created) and TXTSH Fields ..
the flat file which i used has Language, MaterialNumber,description pattern alone..
(eg . E , M001,cookie ) and when i try to load this data..and check in the Monitor - Administration Workbench..it shows as unsuccessful..
The following error msg :
