AudiCLip.play should return a boolean value

Java Experts,
looks like it's a bug in java, the audioClip.play method should return a boolean value indicating whether it was able to play the clip or not. Because sometimes the method doesn't play anything. Right now the method plays asynchronously that may be the reason that it returns a void. Thoughts???
Q.

i agree with you..i also encountered this problem sometimes the play method doesn't play and the programmer has no clue to figure this out programmetically...Looks like this problem has no solution..where are java experts in this forum??

ObjectInputStream returns a wrong boolean value of a object

ObjectOutputStream.writeObject once, then change the boolean value of the Contact object, ObjectOutputStream.writeObject again, but when ObjectInputStream.readObject, it returns SAME boolean values which should be different. can somebody explain me this? please. thx

Did you try the reset() technique again?
You could also have a look at ObjectOutputStream.writeUnshared().
And it's not returning a 'wrong value', it is conserving the object graph of the original object sent, which is what it's specified to do and what it's supposed to do. If you don't want that behaviour use reset() or writeUnshared().

Time a boolean value

I am reading the status of 10 lamps from a serial string. My VI
returns a boolean value according to the status of the lamp. Now I
need to time the on time of each lamp. As soon as a lamp turns off it
should save the time and start adding the time again once the lamp
comes on again. Once the VI is closed and reopend the on time should
appear in the VI for each lamp. And once a lamp comes on it should
start adding to that time. I should also be able to reset the time and
I should also be able to enter a number of hours that a lamp has been
on already. Any suggestions ? Thanks

Hello wv,
do you want someone to develop a program for you? Then you have to pay him/her :-)
Some hints: Make an array for your time values. To reset a timevalue you just need to clear it. To have an offset you just set it in that array. Let the status-vi run in a loop and get the time difference for one loop iteration. Add that delay to the timevalues, if the status of the lamp is on. If you need that timevalues after restarting your VI you should think about a subVI for saving and reading the timevalues.

How to return a boolean in a method?

I have
public int isEven(int num1, int num2)
          boolean even;
          if (((num1 + num2)%2)==0)
               even = true;
          else
               even = false;
          return even;
     }however, it tells me that the return are incompatible types and that an int is required instead of the boolean value.
But when I recall the method I need it to return a boolean not an int >.<
How do I get the method to return a boolean value so it will work with the following code in my main
     if (myGeek.isEven(num1,num2))
System.out.println("Sum of " + num1 + " +" + num2 + " is even");
     else
System.out.println("Sum of " + num1 + "+" + num2 + " is not even");

change
public int isEven(int num1, int num2)to
public boolean isEven(int num1, int num2)get it?Awwwwwww, you stole my thunder. : (

Query with subquery should return value but doesn't

When I run this SQL, it returns no value:
SELECT vfn.cat
FROM vps_fishery_ner vfn, valid_fishery vf
WHERE vfn.plan = vf.plan
AND vfn.cat = vf.cat
AND vf.permit_year = 2010
AND vf.moratorium_fishery = 'T'
AND vfn.vp_num = 211652
AND vfn.ap_year = 2010
AND vfn.plan = 'MUL'
AND vfn.date_issued = (SELECT MAX(date_issued)
FROM vps_fishery_ner
WHERE vp_num = 211652
AND ap_year = 2010);
In order to test, I take out the subquery and run it separately:
SELECT MAX(date_issued)
FROM vps_fishery_ner
WHERE vp_num = 211652
AND ap_year = 2010;
Returns 02-APR-10
Then I paste this date into the original query (using the TRUNC function, of course, since I hardcode only the DDMMYY part of the date):
SELECT vfn.cat
FROM vps_fishery_ner vfn, valid_fishery vf
WHERE vfn.plan = vf.plan
AND vfn.cat = vf.cat
AND vf.permit_year = 2010
AND vf.moratorium_fishery = 'T'
AND vfn.vp_num = 211652
AND vfn.ap_year = 2010
AND vfn.plan = 'MUL'
AND TRUNC(date_issued) = TO_DATE('02-APR-10');
And this returns the required value, 'A'.
So why doesn't the full query with subquery work, if the value that is returned by the subquery is valid and works when you just paste it in?
Thanks.

Hi,
Not sure about your question.
But you say when you uss 01-apr-10 you get the expected results.
So why dont you try using trunc on botht sides
SELECT vfn.cat
FROM vps_fishery_ner vfn, valid_fishery vf
WHERE vfn.plan = vf.plan
   AND vfn.cat = vf.cat
   AND vf.permit_year = 2010
   AND vf.moratorium_fishery = 'T'
   AND vfn.vp_num = 211652
   AND vfn.ap_year = 2010
   AND vfn.plan = 'MUL'
   AND trunc(vfn.date_issued) = (SELECT MAX(trunc(date_issued))
                            FROM vps_fishery_ner
                           WHERE vp_num = 211652
                             AND ap_year = 2010);Rememeber if you are couting on some Index to be used you might want to recheck.
IN answer to your question why it does not return with subquery included, because the TIME PART is not the same.
You yourself proved it by using the supplying only the date part.

Feature request: recursionGuard:performWithGuard() should return a value

It would be better if recursionGuard:performWithGuard () were like LrFunctionContext.callWithContext() and returned the result of the called function. As a general rule, any such "control-flow" wrapper should return the result of the called function.

So far I've been using home-brewed recursion guarding, a.k.a. flag variables, however its hard to imagine returning function results not being a good idea...

Cell with boolean value not rendering properly in Swing (custom renderer)

I have a problem rendenring boolean values when using a custom cell renderer inside a JTable; I managed to reproduce the issue with a dummy application. The application code follows:

}I decided to write a more specific renderer just for that column:

import javax.swing.UIManager;
import javax.swing.table.DefaultTableCellRenderer;
* Cell renderer used only by the DividendElement table

               } else {

          return comp;
      * Override for performance reasons

     public void revalidate() {
          // EMPTY
     @Override
     public void validate() {
          // EMPTY
} // end classBut the rendering comes all wrong (a String saying true or false, not the expected checkbox from the default renderer) and also there is a weird flickring effect as this particular boolean column is editable (per table model, not show here)...
I can post the table model and the other renderer if needed (didn't want to put too much code on the question, at least initiallty).
Should I render a checkbox myself for this cell in the custom renderer? I'm puzzled as I expected the default renderer part of the code to do this for me instead.
Thanks!

camickr
Thats because the default render is a JLabel and it just displays the text from the toString() method of the Object in the table model.What I meant to say is that I expected the JCheckbox not a String representation of the boolean value.
Thats because a different renderer is used depending on the Class of data in the column. Look at the source code for the JTable class to see what the "default >renderer for the Boolean class" is. Then you can extend that or if its a private class then you will need to copy all the code and customize it.At the end I looked at the code and replicated the functionality I needed. I thought than maybe there was a way to avoid replicating the same logic all over again in order to implement this functionality. Good advice, though.
see you learned nothing from your last posting. This is NOT a SSCCE. 90% of the code you posted is completely irrelevant for the described problem. There is abosutelly no need to post the custom TableModel, because there is no need to use a custom TableModel for this problem. The TableModel has nothing to do with how a column is rendererd.The custom table model returns the type of the column (giving a hint to the renderer on what to expect, right?) and for the one that had a problem it says than the class is Boolean. That's why I mentioned it:
public Class getColumnClass(int columnIndex) {
    // Code omited....
You also posted data for 4 columns worth of data. Again, irrelevant. Your question is about a single column containing Boolean data, so forget about the other columns.
When creating a SSCCE you don't start with your existing code and "remove" code. You start with a brand new class and only add in what is important. That way hopefully if you made a mistake the first time you don't repeat it the second time.That's what I did, is not the real application. I copy & pasted code in a haste from this dummy program on this forum, not the best approach as it gave the wrong impression.
Learn how to write a proper SSCCE if you want help in the future. Point taken, but there is NO need for you to be rude. Your help is appreciated.

Jose.

Change boolean value in a method

How could the following be done:
I have an object file deserialized and I want to call its methods. I want one of the methods to return a boolean. When I call this method I want the value of boolean to be set to true. So when I want to call this method again I want the boolean to be set to true. Therfore I will be unable to call this method.
Below is the code that I have used.
Thanks in advance
public interface Call
public void execute();
public boolean test();
import java.util.*;
public class Example implements java.io.Serializable,Call
public void execute()
System.out.println("Example has printed out");
   public boolean test()
     System.out.println("The test method has been called");
}Should I provide all of the code? Or is the above enough

I'm glad you've bought a book, I hope you find it enlightening. Incidentally, I'm not annoyed, only amused, but either way if we don't understand your questions, we can't help you can we ?
Do try to remember that we don't know what you're trying to achieve here - we don't have the big picture.
So in your update, I still don't know, really, what you're getting at. I particularly don't understand what (if any) relevance you think Serialization has to this problem. However, here is my best guess:
import java.util.*;
import java.io.*;
public class Example
   implements Serializable,Call
   public void execute()
      if(!test())
         System.out.println("Will not do the work");
      else
         System.out.println("Will do the work");
         doWork();
   public void doWork()
      // This method will ONLY get called the first time you
      // call execute() and never again.
   public boolean test()
      System.out.println("The test method has been called");
      if( m_status == true )
         m_status = false;
         return true;
      return false;
   // The status of the test - initially true
   private boolean m_status = true;
}

The Boolean value getting null?

Hello EveryBody........
Any one help me why the Boolean value gives always null instead of false;
what will the default value of this.........
       private Boolean result;
     public Boolean getResult() {
          return result;
     public void setResult(Boolean result) {
          this.result = result;
     }please help how to set the default false without initialize private Boolean result = false;

Default initialization for Instance reference variable is null reference .
Default initialization for Instance primitive variable is depends on its type.
Local variable should be initialize before they used.
got it?
But this question should be in "New to Java" this forum.

Boolean Values in CALL TRANSFORMATION id ?

Hi,
I have Boolean values of the XSDBOOLEAN Domain, so ABAP->XML "id" transformation returns "True" and "False" for these values. What I need are "X" and " " respectively.
The questions is: can I use the modified transformation "id" to replace the "True" and "False" with "X" and " ", and how the modified transformation should look like?
Thanks, Srdjan

I couldn't find domain XSDBOOLEAN in our system, however you should use the values defined in the Value range tab.

Boolean values

Does anyone know how Q&A handle boolean values? If a dataset includes a column with true/false values, what is the correct syntax for a Q&A query that filters on this value.
Carla Sabotta

I think it will work normally as other columns
for e.g. consider table students with column IsEligible having boolean values
Then Q/A query like "Count of students where IsEligible is true" should work fine and return count of students where IsEligible is true
Moreover If we set a proper data type of column then it should work more intuitive
E.g If we set IsEligible column to have data type as TRUE/FALSE and set word Eligible to be its synonym then Query like "Count of Eligible Students" should also work
Let me know if this answers your question.
Thanks,

How to return a specific value in an if statement

Hi all,
Need some help regarding a report Im creating. I am a total newbie to SQL so I guess this question is really simple to all of you.
I have a column, UDF58, in a table that can have 3 different values, 10, 25 and 35.
If the value is 10 I want the formula to return 1.
If the value is 25 it should return 2 and if it is 35 the return should be 3
I tried the following:
IF :UDF58=10 THEN RETURN :UDF10='1';
I do not get any error message when compiling but it do not return any value at all....
Patrik

Do not know if you are dealing with number or varchar2 column, so here are two ways -- there are others...
SQL> create table t (udf58 number);
Table created.
SQL> insert into t values(10);
1 row created.
SQL> insert into t values (25);
1 row created.
SQL> insert into t values(35);
1 row created.

If you received character strings' variable value such as '56,34',
then you can get it as follows.
where regexp_instr( '56,34' , '(^|,)('||t.catid||')(,|$)') >= 1
Ex)
with
test_param as
(select '56' param from dual union all
select '34' from dual union all
select '56,34' from dual union all
select '5,344' from dual
,test_data as
(select 5 catid from dual union all
select 3 from dual union all
select 56 from dual union all
select 34 from dual union all
select 566 from dual union all
select 344 from dual
/* End of Data */
select p.param, t.catid
from test_data t, test_param p
where regexp_instr( p.param, '(^|,)('||t.catid||')(,|$)') >= 1
PARAM      CATID
56            56
34            34
56,34         56
56,34         34
5,344          5
5,344        344

Conditional display using Pl/SQL function body returning a boolean

I am having issues with conditional display of a report.
I have to select lists: p50_facility and p50_supervisor.
I have entered the below pl/sql function body returning a boolean
Begin
if (:p50_facility is null or
:p50_supervisor is null) THEN
Return False;
Else
Return True;
End if;
End;
No matter what values my items are set to (null, not null), the report shows.
What am I doing wrong?

Hi,
The values for the lists will be null only until the first time the page is submitted. Thereafter, the value is likely to be '%null%'
You will need to do something like:
BEGIN
IF (:P50_FACILITY IS NULL OR :P50_FACILITY = '%' || 'null%' OR :P50_SUPERVISOR IS NULL OR :P50_SUPERVISOR = '%' || 'null%') THEN
RETURN FALSE;
ELSE
RETURN TRUE;
END IF;
END;Andy

AudiCLip.play should return a boolean value
