Please tell me if this can be written in a more simpler manner. Also please correct this code. I am tired after trying many times.

What's wrong with this simple code?

What's wrong with this simple code? Complier points out that
1. a '{' is expected at line6;
2. Statement expected at the line which PI is declared;
3. Type expected at "System.out.println("Demostrating PI");"
However, I can't figure out them. Please help. Thanks.
Here is the code:
import java.util.*;
public class DebugTwo3
// This class demonstrates some math methods
public static void main(String args[])
          public static final double PI = 3.14159;
          double radius = 2.00;
          double area;
          double roundArea;
          System.out.println("Demonstrating PI");
          area = PI * radius * radius;
          System.out.println("area is " + area);
          roundArea = Math.round(area);
          System.out.println("Rounded area is " + roundArea);

Change your code to this:
import java.util.*;
public class DebugTwo3
     public static final double PI = 3.14159;
     public static void main(String args[])
          double radius = 2.00;
          double area;
          double roundArea;
          System.out.println("Demonstrating PI");
          area = PI * radius * radius;
          System.out.println("area is " + area);
          roundArea = Math.round(area);
          System.out.println("Rounded area is " + roundArea);

Welcome to the forum. I think that George123 has your problem and its solution well in hand. Follow his good advice and you will have solved this problem. One other thing though just for future reference. If you post your code, here, you are going to want someone to be able to read it easily. Please use code tags when posting next time and your code will be much easier on the eye. You can find out about them here:

What's wrong with this mini-code? (Trying to draw graphics).

Could someone please help me fix what's wrong the following test-program?:

        System.out.println("works2");
}Any help would be greatly appreciated!
Thanks in advance!

Also, all Swing code should be called from the Event Dispatch Thread. It probably isn't hurting much in your case. But, in the body of main, do this (instead of the comment, put what you currently have as the body of main):
EventQueue.invokeLater(
new Runnable()
      public void run()
          // Your current body of main.
});

What is wrong about this DefaultTableModel code?

What is wrong with this idoc code snip?

Hi all here's the code that's supposed to give me a default value for a metadata in check-in:
1. <$if dDocAccount like "test*"$>
2. <$dprDefaultValue="Test"$>
3. <$elseif userHasRole("TesterA") or userHasRole("TesterB")$>
4. <$dprDefaultValue="A or B"$>
5. <$elseif userHasRole("TesterC") or userHasRole("TesterD")$>
6. <$dprDefaultValue="C or D"$>
7. <$else$>
8. <$dprDefaultValue="Not A nor B nor C nor D"$>
9. <$endif$>
Now if I leave the code like that only the first 2 lines work meaning that if first condition fails then the whole code stops working even though line 3 is true... is there something wrong in just calling dDocAccount on its own? never seen that happen before.
If I change that first line for <$if *#active.* dDocAccount like "test*"$> then this first condition won't work but the rest (line 3+) does work!
please help!!

Hmmmm,
If your first two lines work if true then the issue is with the elseif lines right?
userHasRole("foo") returns true or false. Can you wrap userHasRole("foo") in an "isTrue()" function and test that way?
What about exploding the OR statement and writing a bunch of elseifs to see if it works that way.
The other thing you can do is to wrap your OR clause itself in parens
<$elseif ((userHasRole("foo")) or (userHasRole("bar")))$>
do stuff
<$endif$>
let us know what works for you
Warmly,

}i really need some assistance at the following areas of code :
where the database results are set to attributes of one bean varabridgment (Type Abridgement) - the declaration and use of this bean.
and where this bean is then added to another bean abridgeresults (Type Results) as a List collection.
i get a null pointer exception when i try to retrieve the List from abridgeresults object of Type Results Bean.
i would really appreciate some assistance in this - i really need to go to sleep now - but cant until i solve this issue. - thanks all in advance.

below is exception outputed to tomcat log file.
it is thrown at the following line of code in the jsp that tries to get the List object :
currently jsp code to retrieve List: <% List myAbridgments = (List) request.getAttribute("results");
for (int i = 0; i < myAbridgments.size(); i++) {
abridgment = (Abridgment) myAbridgments.get(i);
%>
line that gives problem is
(results_jsp.java:95)
//myAbridgments - is variable where i store the List object in jsp scriptlet
for (int i = 0; i < myAbridgments.size(); i++) {
Also, i dont understand why the servlet keeps on forwarding to the results.jsp when i even comment out the line of code to forward request oobject to results.jsp - i recompile copy it over original and restart tomcat - but still i get the null pointer exception in results_jsp - but i'm no longer forwarding anything to this jsp. --- i want to do some out.printline statemets in servelt to see some of the data from the query - but i cant as it just forwrads the request to results.jsp - how can i output the data to look at debug - i dont have a log4j logger setup and dont have IDE to be able to place break points - so wanted to just output stuff to browser to have a look at what was going on - but can't as just forwards request on ?

What's wrong with this button code

Dear All,
I am trying to set up a button handler for many buttons
rather just one. The
intention of this code is to say if I press Load1 to Load40
that button and
only that button's alpha should change to 50%. This code
makes them all 50%
alpha when the frame loads rather than on the onPress event.
Can someone please help me out with this one?
i = 0;
while (i<40) {
this["Load"+i].onPress = btnEvaluate(this["Load"+i]);
++i;
function btnEvaluate(target_btn:Button) {
target_btn._alpha = 50;
Thanks again.
Alastair MacFarlane

kglad,
Thanks again. What would this group do without your help.

Can't gotoAndStop ...what's wrong with this button code?

Hi,
I'm totally stumped as to why I can't navigate to another frame.
I have put 2 days into this simple problem now and I'm ready to give up and go back to AS2.
Please help!
I'm using CS4; publish settings AS3, 10.0
I have a button on frame 2 that should take me to frame 3 when clicked.
(So far I've tried a hundred different ways but I don't get to frame 3...)
Different things I tried...
> Creating the button dynamically from the library...
> Inserting it statically from the library on frame 2...
> referencing the mainTimeline through a variable...
> wrapping the gotoAndStop action in another function...(if placed directly on the timeLine the movie correctly goes straight to frame 3)
> naming frame 3...
> using 'nextFrame' instead of 'gotoAndStop'...
etc..
In most cases I don't get an error in the output panel and no compiler error either; it just doesn't work!!!
(Just stays on the same frame after I click the button)
Here's the code I think should work; but doesn't:
function moveTo3 (event:MouseEvent):void {
trace("button_clicked"); // always traces correctly; but movie does not go to frame 3 !!!
gotoAndStop(3);
f_btn.addEventListener(MouseEvent.CLICK, moveTo3);
WHAT AM I MISSING HERE?
Thanks in advance ...

Hi Ned,
I have to run out and don't have the time to deal with it right now but you're RIGHT.
I do have an 'onEnterFrame' listener on frame 1 !
It's doing some animation with a symbol and I don't think I removed the listener itself.
I just set the object to null when it reached [alpha:0].
THANKS!
I'll check it out as soon as I can but I really think you got me looking in the right direction now.
Thanks again,
Connor
(I'll post an update when I get back to it)

What is wrong with this java

Hi guys
I have a little experience with java
I have to classes LoginScreen and newUser. LoginScreen calss reads data from text file which is user name and passwords then extracts usernames and load them to Comobox .in the first position of the Comobox I Inserted Create New Profile string .When the user click on it another Screen will appear which is instance of the newUser class .And that will allow new user to enter his name and press Ok button to confirm the operation ,then the new Screen will be closed .When that happen I want new user name be inserted into the Combox in LoginScreen.Anybody has any clue why the code below does not work correctly .

1. You have to precisely define "does not work."
2. You have to use code tags to make your code readable. Re-paste it from the original source (not from you post here), highlight it, and clicke the CODE button above the message entry box.

What is wrong with this trigger code?

Hi folks,
Just wondering whether I might be missing something here about Oracle 9i, that one of you might notice, either from the syntax perspective, or regarding a bug? The code below compiles in the database I have, but the trigger does not fire, and no data is being inserted into the tables. The trigger is owned by sys, and the insert statements are in dynamic sql because I don't want the trigger not to compile if ever the tables are deleted from the b1dev schema.
Incidentally, this same trigger works well on Oracle 10.2.1.0 and Oracle 11.1.0. Any feedback would be much appreciated.

I have taken out the 'commit' and have added the 'when others then null' exception clause, but I would imagine there is a better way to do it than this? I don't want to do an insert into another table either. With Oracle 11g, this gives me the compile time warning....

What's wrong with this small code?

hi, there,
I tried to compile the following code and get the error like:
Can't make static reference to non-static reference in line System.out.println(msg);
It is wired to me. Could somebody give a hint? Really appreciate!!!
Jianmin
import java.awt.*;
import java.awt.event.*;
public class fram extends Frame
String msg="hello";
public static void main(String arg[])
fram f=new fram();
Button b=new Button("Click");
b.addActionListener( new ActionListener() {
public void actionPerformed(ActionEvent e) {
System.out.println(msg);
f.add(b);
f.pack();
f.show();

Thanks a lot!!! it works.
msg is non-static, that is 'instance' variable,
and you can not acces it from static context. Simply
speaking you have to use b.msg, will not work
eather though

What is wrong with this Java class and method?

Created a managed bean and following method as shown below.
public void setEvent(DisclosureEvent disclosureEvent, CoreShowDetail detail) {
if (disclosureEvent.isExpanded()) {
detail.setDisclosed(!detail.isDisclosed());
-- Then integrated above in the following jspx.
<af:showOnePanel inlineStyle="width:400px;height:300px;"
binding="#{ShowApanel.showOnePanel1}"
id="showOnePanel1">
<af:showDetailItem text="ADF Faces Components"
binding="#{ShowApanel.showDetailItem3}"
id="showDetailItem3" disclosureListener="#{ShowApanel.setEvent}">
<af:panelHeader text="ADF Faces Components First Child"
binding="#{ShowApanel.panelHeader6}"
id="panelHeader6"/>
<af:panelHeader text="ADF Faces Components Second Child"
binding="#{ShowApanel.panelHeader5}"
id="panelHeader5"/>
</af:showDetailItem>
<af:showDetailItem text="Architecture"
binding="#{ShowApanel.showDetailItem2}"
id="showDetailItem2"
disclosureListener="#{ShowApanel.setEvent}">
<af:panelHeader text="Architecture First Child"
binding="#{ShowApanel.panelHeader4}"
id="panelHeader4"/>
<af:panelHeader text="Architecture Second Child"
binding="#{ShowApanel.panelHeader3}"
id="panelHeader3"/>
</af:showDetailItem>
</af:showOnePanel>
THE ISSUE:[b]
I am still not able to programmatically disclose or undisclose the panel component.
Where am I going wrong? Please help.
Thanks,
Ruchir

Hello Frank,
I put several print statments but none of them is executing on browser. Does this mean that the method is not being called even once?
public void setEvent(DisclosureEvent disclosureEvent, CoreShowDetail detail) {
System.out.println("HelloServer Exiting ...");
if (disclosureEvent.isExpanded()) {
System.out.println("HelloServer Exiting1 ...");
// detail.setDisclosed(!detail.isDisclosed());
System.out.println("HelloServer Exiting2 ...");
Thanks,
Ruchir

What's wrong with this widget code?

Hi everyone,
(I hope this is a good place to put this) I'm trying to build a widget in Dashcode, and one of the things I want to do is run a system command (specifically "ps -ax"). I enabled command line access in the widget attributes, and I now have:
var processes = widget.system("/bin/ps -ax", NULL);
The problem is that "processes" is always undefined. I read on here that there's a bug that if the output is too long, then the variable is undefined. So I tried substituting the command with this:
var processes = widget.system("/bin/ls ~/", NULL);
When I run the command in Terminal, the output is minimal:
Desktop Documents Downloads Library Movies Music Pictures Public Sites
But when I try to run that in Dashcode, it still returns undefined. Am I missing something obvious here?

bump I'm still at a standstill with this. Any ideas?
Thanks!

I can't figure out what's wrong with this code

First i want this program to allow me to enter a number with the EasyReader class and depending on the number entered it will show that specific line of this peom:
One two buckle your shoe
Three four shut the door
Five six pick up sticks
Seven eight lay them straight
Nine ten this is the end.
The error message i got was an illegal start of expression. I can't figure out why it is giving me this error because i have if (n = 1) || (n = 2) statements. My code is:
public class PoemSeventeen
public static void main(String[] args)
EasyReader console = new EasyReader();
System.out.println("Enter a number for the poem (0 to quit): ");
int n = console.readInt();
if (n = 1) || (n = 2)
System.out.println("One, two, buckle your shoe");
else if (n = 3) || (n = 4)
System.out.println("Three, four, shut the door");
else if (n = 5) || (n = 6)
System.out.println("Five, six, pick up sticks");
else if (n = 7) || (n = 8)
System.out.println("Seven, eight, lay them straight");
else if (n = 9) || (n = 10)
System.out.println("Nine, ten, this is the end");
else if (n = 0)
System.out.println("You may exit now");
else
System.out.println("Put in a number between 0 and 10");
I messed around with a few other thing because i had some weird errors before but now i have narrowed it down to just this 1 error.
