Simple Java Question - How to test if a given string is numeric or not

Hi Experts,
I have written one Java program. It fetches user ID from UME. The code is as below:
Iterator itr = role.getUserMembers(true);
while (itr.hasNext()) {
String uniqId = (String) itr.next();
IUser thisUser = myUserFactory.getUser(uniqId);
wdComponentAPI.getMessageManager().reportSuccess("here "+thisUser.getUid() );
Used ID is thisUser.getUid() . I have to find out all user IDs which are numeric.
Do we have any standard Java program (API) to find out whether thisUser.getUid() is numeric or not.
Regards,
Gary

Hi
Just try to parse this string to integer or long number and catch the NumberFormatException.
Somthing like:
try
Integer.parseInt(userIdString);
catch(NumberFormatException e)
//do sume thing when user id is not number
good luck

Simple Java Question - How to Overwrite Set

After working so much in Java, wondering how do i overwrite java.util.Set
My pojo is Set of associated object. For example
class Parent
private Set child = new HashSet(0);
public Set getChild() {
return this.child;
I wanna overwrite set of child objects in pojo with the set passed from UI tier
Any pointers/suggestions will be highly appreciated

public void setChild(Set child) { this.child = child; }or if you need more control over the Set instance:
public void setChild(Set child)
this.child.clear();
this.child.addAll(child);
}

Simple Query Question - How do I return the Last 3 records of a Table?

Question.
For example, I have a table that has 50 records.
How do I, specify in SQL to only return the last 3 records of the table.
Select a.* from table a where ????

I was just trying to show an example to a friend on
how something like this would work and if it was even possible. But it won't work. Here's a simple example:
SQL> create table emp
2 (id)
3 as
4 select object_id
5 from   all_objects
6 order by object_id;
Table created.
SQL> select *
2 from (select rownum rn
3               ,b.*
4         from   emp b)
5 where rn > ( select (max(rownum) - 3)
6                from    emp)
7 ;
        RN         ID
     40830      55891
     40831      55892
     40832      55893So far, so good. These are the "last 3" rows inserted. Now delete a bunch of rows and insert 3 new ones:
SQL> delete emp where id < 40000;
33423 rows deleted.
SQL> commit;
Commit complete.
SQL> insert into emp values (60000);
1 row created.
SQL> insert into emp values (60001);
1 row created.
SQL> insert into emp values (60002);
1 row created.
SQL> commit;
Commit complete.
SQL> select *
2 from (select rownum rn
3               ,b.*
4         from   emp b)
5 where rn > ( select (max(rownum) - 3)
6                from    emp)
7 ;
        RN         ID
      7410      55891
      7411      55892
      7412      55893Here's the problem. Even though the "last 3 rows" are 60000 - 60002, I still get the same ones as the first query.

class HelloARP {
public static void main (String[] arguments) {
System.out.println("What's good ARP?");
- all responses and help are welcomed. Thank you ahead of time for anyone that can help me get started.

Hi
First of all uninstall your current JDK installation, if you can get to the registry delete the registry entries for the old version of java which was there on your machine.
Now do a fresh install of your j2sdk1.4.1, make sure that you will install the JRE with the J2SDK1.4.1.
Once you are done, set your classpath in autoexec.bat if you are using Windows 95/98
or set your environment variables if you are using Win NT/2000/XP.
If using solaris or other unix flavors see the included installation instructions provided.
Let me if you face the same problem.
Thanks

Simple Java Question 2

hey everyone!
im stuck, on the math part.
i need to add a formula to my applet, x = y*z, for example. For fixed values of y and z. So lets say y = 5 and z= 3. How do i get "15" to be displayed when an applet is started.
I have looked through java.math but did come across anything but complicated stuff.
your help is very appreciated.

int y = 5, z = 3;
System.out.println(y*z); //prints out '15'This will be printed out to standard output (the shell), for an application.
I'm not sure how you want to print this using your applet.
But the main point is that simple maths can be done using operators on primitive data types (int, byte, short, double, long, ) Check out this important resource.
I recommend you read the whole tutorial, or at least the following sections:
Learning the Java Language
Writing Applets
Writing Swing Applets

Three simple java questions

Issue 1:

totaliNumber = 1001;
if(totaliNumber > 9999)
totaliNumber = 1001;
iNumber = totaliNumber;
++totaliNumber;This is only giving me the number 1001 each time it is called. if theres any other way to give me the next number other than keeping a count, let me know...

Simple java questions!

Hi!
Can someone tell me the answers of these questions, you can just bold the correct answer.Any help will be appreciated.
Thanks in advance.

sandy.
1) Which of the following software components is not included in the standard Java SDK 2?
(a)appletviewer(b)JMF(c)Jar tool(d)Swing(e)none of the above
2) Which of the following is an abstract class in the Java API?
(a)int (b)Integer (c)WindowListener (d)WindowAdapter (e)none of the above
3) Which of the following types can be stored in a TreeMap?
(a)int (b)boolean (c)char (d)String (e)none of the above
4) How many main methods are allowed in a java program which comprises four user-defined classes?
(a)one (b)two (c)three (d)four (e)none of the above.
**********************************************************************

about that main methods: i find it strange that only 1 main method is allowed, i would say: alot :)
Just to give an example of the possibilities:
public class Main {
public static void main (String[] args) {}
public static void main (int i) {}
public void main() {}
public void main (int i, String blah) {}
}All is allowed, only the
public static void main (String[] args) {}will be used as the startup method for the program.
So in other words, that question not complete.

A simple Java question...

How to wrap the text on the Button in Java?
For example, the text on the button is too long, I would like to switch it into two lines, but I don't know how to do it. Can anyone tell me how to do it?
Thank you very much!!!

Someone told me about this....
after Java 1.1.7 and Swing 1.0.3, Swing do enable HTML rendering, so you can create a multiline button with the HTML code. eg.
JButton myButton = new JButton ("<html><center>Chevrolet<br>Light Truck</center></html>");
here have more 3 methods for create multiline button.
1. combination of JLabels and the JButton
JButton myButton = new JButton();
myButton.setLayout(new BorderLayout());
JLabel myLabel1 = new JLabel("Line1");
JLabel myLabel2 = new JLabel("Line2");
myButton.add(BorderLayout.NORTH,myLabel1);
myButton.add(BorderLayout.SOUTH,myLabel2);
2. create a new ButtonUI that formats your text properly
3. extend JButton and overriding paint method. tokenize string based on \n and recalculations spacing (no good)
Does it really work?

Simple IPhoto Questions-How to reduce picture file size?

Hello,
I know how to reduce the size of photos using the Mail program, but is there a simple way to reduce the size of photo files and keep them for sending through the internet at later dates. I would like to keep the photos at their original size for viewing, but transfer photos to a file where they will be used to send over the net in much smaller format size.
thanks

As Larry says, you can resize the pics on Export using the File -> Export command.
and keep them for sending through the internet at later dates.
The intention in iPhoto is that you would only reduce the size on a case-by-case basis, rather than resize the whole library. As iPhoto always maintains the Originals this require quite a lot of disk space

Hi Ravinda,
You add to one of your WD RFC Adaptive model relations not instance of com.sasol.pr.create.Bapimereqitemimp$Bapimereqitemimp_List BUT com.sasol.pr.create.Bapimereqitem$Bapimereqitem_List
Check the place where you instanciate your model, establish relations and bind model to model class.

Simple Java Question vs. Visual Basic 6

What are the core advantages in using Jbuilder9?
What are the disadvantages of using Jbuilder9?
And what advantages does Jbuilder have over VB6?
And What is UI? And IDE????

I think you first need to ask yourself wether Java or
Microsoft is the way to go. Java is portable and secure
(among other things).
If you are looking for graphical tools to build web
applications, you may want to consider Java Studio
Creator, which will be available in Early Access in a
few weeks time:

Simple Java Question (Hopefully)

I'm not sure if anyone out here is familiar with ClearCase, I'm sure there are some, but I am trying to create some basic classes that perform various cleartool shell out commands, one of which returns the some information about ClearCase code repositories.
When I execute a command line "cleartool lsvob" via cmd here's what I get:
\mt_group \\happy\vobdata\vobstore\mt_group.vbs public
* \company_cmtools \\happy\vobdata\vobstore\company_cmtools.vbs public
\loc_test \\happy\vobdata\vobstore\loc_test.vbs public
\iais \\happy\vobdata\vobstore\iais.vbs public
\loc_test1 \\happy\vobdata\vobstore\loc_test1.vbs public
* \ccase_tool \\happy\vobdata\vobstore\ccase_tool.vbs public
\ddts \\happy\vobdata\vobstore\ddts.vbs public
\cmtools_a2 \\happy\vobdata\vobstore\cmtools_a2.vbs public
\pams \\happy\vobdata\vobstore\pams.vbs public
However, when I try to do this via a class file it just sits there and doesn't do anything. When I change the command string to "cleartool lsvob -s" it prints:
\mt_group
\company_cmtools
\loc_test
\iais
\loc_test1
\ccase_tool
\ddts
\cmtools_a2
\pams
Does Java have a problem with white spaces? Here is the code I have:
import java.lang.*;
import java.io.*;
import com.oroinc.text.perl.*;
public class GetVobMount {
     String cleartool;
     String os = System.getProperty("os.name");
     String cmd = " lsvob";
     public String getVobs () {
          Perl5Util perl = new Perl5Util();
          if (perl.match("/Win/i", os)) {
               cleartool = "cmd /c cleartool.exe";
          } else {
               cleartool = "/usr/atria/bin/cleartool";
          StringBuffer data = new StringBuffer();
          System.out.println(cleartool + cmd);
          try {
               Runtime r = Runtime.getRuntime();
               Process p = r.exec(cleartool + cmd);
               p.waitFor();
               DataInputStream in = new DataInputStream(p.getInputStream());
               String input;
               while ((input = in.readLine()) != null) {
                                     data.append(input);
                    data.append("\n");
          } catch (Exception e) { System.out.println(e); }
          return data.toString();
     public static void main (String [] args) {
          GetVobMount vobs = new GetVobMount();
          System.out.println(vobs.getVobs());
}Of course this won't work in an enviroment that isn't using ClearCase but perhaps there is a reason why java won't return a string of:
\something \\server\path\dir\something.vbs public
Any help or suggestions will be greatly appreciated.
-Wes

Howdy... I myself have done a lot of clearcase work with a Java app that runs on both UNIX and NT, so hail to you.
So the problem here is that the spawned process blocks? And there is no way to get it to resume?? Isn't this a bug?? The original code seems perfectly acceptable.
I've encountered the same problem. My app. was running some system calls and there were some unusual error messages due to system/server problems. The java app should've handled it fine (I handle STDERR), but instead my java app FROZE, no doubt because the spawned process went into this blocked state as Chuck described. In my case, when the system/server error was fixed and the error messages went away, my app stopped locking up.

Simple audio question - how to mute a track?

Have a timeline with one video and two audio tracks - both tracks are stereo.
I need to mute one of the audio tracks to make edits to the other.
How can I mute one of the audio tracks?

Awesome - that's what I was looking for! Ton of clips so hitting shift-Z and then selecting the entire length of the track seems to work.
Where is that "V" feature in the menus?
