A problem with args[i]
Hi, I'm totally new to Java and I have a problem with my first program. It has to read the numbers from the input and checks wheter it is a prime number.
This is what I have so far:
public class PrimeNumbers
public static boolean isPrime(int n)
if (n<2) return false;
if (n==2||n==3) return true;
boolean prime=true;
int limit=(int)Math.sqrt(n);
for (int i=2; i<=limit; i++)
if ( n%i==0 )
prime = false;
break;
return prime;
public static void main ( String[] args )
int n,i;
for(i=0;i<=args.length;i++)
n=args;
if (isPrime (n))
System.out.println (n+ "is Prime");
else
System.out.println (n+ "is not Prime");
It shows an error in line : "n=args[i];". Can you tell me how to fix it? Thanks :*
Integer.parseInt(args)

Problem with JFrame and busy/wait Cursor
Hi -- I'm trying to set a JFrame's cursor to be the busy cursor,
for the duration of some operation (usually just a few seconds).
I can get it to work in some situations, but not others.
Timing does seem to be an issue.
There are thousands of posts on the BugParade, but
in general Sun indicates this is not a bug. I just need
a work-around.
I've written a test program below to demonstrate the problem.
I have the problem on Solaris, running with both J2SE 1.3 and 1.4.
I have not tested on Windows yet.
When you run the following code, three JFrames will be opened,
each with the same 5 buttons. The first "F1" listens to its own
buttons, and works fine. The other two (F2 and F3) listen
to each other's buttons.
The "BUSY" button simply sets the cursor on its listener
to the busy cursor. The "DONE" button sets it to the
default cursor. These work fine.
The "SLEEP" button sets the cursor, sleeps for 3 seconds,
and sets it back. This does not work.
The "INVOKE LATER" button does the same thing,
except is uses invokeLater to sleep and set the
cursor back. This also does not work.
The "DELAY" button sleeps for 3 seconds (giving you
time to move the mouse into the other (listerner's)
window, and then it behaves just like the "SLEEP"
button. This works.
Any ideas would be appreciated, thanks.

I still believe you would need a thread for the time consuming task, and that invokeLater is something you only need to use in a thread different from the event thread. -
Firefox 6.0.2 keeps on crashing, problems with ajax calls
Hi,
I am using the jquery form plugin to make ajax calls on my sites, when i invoke the plugin and have Firebug open I get this message:
Could not convert JavaScript argument arg 0 [nsISupports.QueryInterface]
[Break On This Error] callback.data = aElem....getComputedStyle(callback.data, '');
rfhelper32.js
Firebug also tells me that it's limit has been reached 1571 entries shown.
Can someone tell me why this is happening; is there a problem with Firefox that will be fixed. It's not happening in IE9
Here is the information from a recent crash report (which may or not be related to the above problem!)

Problems with spaces in file or directory names and Word.exe
Hi
I'm trying to open a file with Word from my java aplication, and I have a problem with some file/directory names.
I have this
String cmd = "c:\\Program Files\\Microsoft Office\\Office10\\WINWORD.EXE" + " " + path;
try {
Runtime.getRuntime().exec(cmd);
} catch (Exception errorea){ }
Here is what happens:
if path is something like this: "c:\people\info.doc" , there's no problem, Word opens the document, but if path contains blank spaces somewhere, it doesn't work. For example:
path = "c:\Documents and Settings\info.doc"
path = "c:\Hi everybody\info.doc"
path = "c:\tests\test results.doc"
with the above examples it doesn't work :( Word tries to open "c:\Documents", "c:\Hi" or "c:\tests\test".
Can anyone help? thanx a lot ! : )Hint: use the variant Runtime.exec(String[] args).
Create a command array, with each token in a separate argument. The entire filename with spaces goes into one argument. -

Hello,
I am having a problem with a program I am trying to write. The idea of the program is to:
A) read a list of movies list from a text file
B) create an object for each movie using the information from the text file
C) place the objects into an arrayList
My problem is that when I check my arrayList it seems to only contain multiple copies of the first movie read from the text file. Here is my code
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;
import java.io.PrintWriter;
import java.io.FileOutputStream;
import java.io.FileNotFoundException;
import java.util.ArrayList;
public class MovieReader
PrintWriter outputStream = null;
public void readFile()
try
BufferedReader in = new BufferedReader(new FileReader("movie.txt"));
String str;
while ((str = in.readLine()) != null)
process(str);
in.close();
catch (IOException e)
e.printStackTrace();
ArrayList <ValidMovie> movieList = new ArrayList<ValidMovie>();
private void process(String line)
String[] array = line.split("\t");
int i = 0;
for ( i = 0; i < array.length; i++)
String tempTitle = array[0];
String tempYear = array [1];
String tempRating = array [2];
String tempFormat = array [3];
ValidMovie uuj = new ValidMovie(tempTitle, tempYear, tempRating, tempFormat);
movieList.add(uuj);
System.out.println("item at index 1 is: " + movieList.get(1));
//~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
private void writeFile(String [] arrayL)
String [] arrayWrite = arrayL;
//~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
//$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
public static void main(String[] args)
MovieReader mv = new MovieReader();
mv.readFile();
//$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
}This is the code that creates an object for each movie:
import java.io.Serializable;
public class ValidMovie implements Serializable
private String title;
private String year;
private String rating;
private String format;
public ValidMovie()
public ValidMovie(String tTitle, String tYear, String tRating, String tFormat)
title = tTitle;
year = tYear;
rating = tRating;
format = tFormat;
//Getters for title, year, rating and format
public String getTitle ()
return title;
public String getYear ()
return year;
public String getRating ()
return rating;
public String getFormat ()
return format;
public String toString ()
return title + "\t" + year + "\t" + rating + "\t" + format;
}The following is what I have in the movie.txt file:
Bamboozled 2000 2 DVD
What Lies Beneath 2000 1.5 DVD
Beneath the Planet of the Apes 1970 1 DVD
You Can Count On Me 2000 3.5 Theater
And finally this is the result when I run the code:
item at index 1 is: Bamboozled 2000 2 DVD
item at index 1 is: Bamboozled 2000 2 DVD
item at index 1 is: Bamboozled 2000 2 DVD
item at index 1 is: Bamboozled 2000 2 DVD
I am sure that it is something simple that I am overlooking but I cannot figure it out. When I change the index in the code:
System.out.println("item at index 1 is: " + movieList.get(1));to 0 or 2 or 3 then result is the same, it will just show the first movie in the text file. Any help would be greatly appreciated. ThanksThanks for the reply, it helped but I am now getting 4 of each of the movies after adding you suggestion. This is much better now I just need to figure out why the loop is causing the extra copies. Thanks again :)
Item 0: Bamboozled 2000 2 DVD
Item 1: Bamboozled 2000 2 DVD
Item 2: Bamboozled 2000 2 DVD

Advance level drawing problem with Jframe and JPanel need optimize sol?
Dear Experts,
I m trying to create a GUI for puzzle game following some kind of "game GUI template", but i have problems in that,so i tried to implement that in various ways after looking on internet and discussions about drawing gui in swing, but i have problem with both of these, may be i m doing some silly mistake, which is still out of my consideration. please have a look at these two and recommend me one of them, which is running without problems (flickring and when you enlarge window the board draw copies (tiled) everywhere,
Note: i don't want to inherit jpanel or Jframe
here is my code : import java.awt.BorderLayout;

Installation problem with Siebel8.0 on Oracle Enterprise Linux 4 system
We are having installation problem with Siebel8.0 on Oracle Enterprise Linux 4 system.
Using interface, when installation come up to “Installing Wizard” window where Gateway Name Server Configuration window should take place, everything just freeze up

user605023I'm facing the same error message while install Siebel 8.0 on OEL. But before I had this ksh problem, it complains about disc space first, and I actually has plenty of disk space under the directory (it needs only 0.7 G and I have 17G free). Anybody has encountered such problem before?

Design problem with JScrollPane
First, I have problems with english. I hope u understand without problems that Im trying to say here. Sorry about that.
Mi problem is whit a JScrollPane. I want to put an image whit a predefined size for draw inside it. I dont have any information about it, just the size. I want to put it in a JPane. The best choice is use the JPane area. The problem is that I want to use a JScrollPane because the image is bigger that the visualization area.
Im unable to put a Canvas in the ScrollPane, or a JPane whit a predefined size or an image whit a predefined size. Im sure that is a design problem. Somebody can tell me something I can start whit? What do u think is better choice to put inside a JScrollPane?
I dont send any source code because I dont have anything else that is show in the example.

Problem with static and nonstatic objects in same code?
Hi everyone, I am working on a project and I kept running into an odd problem where my code would compile but when I went to run the code I would get an exception. I finally narrowed my problem down to a small fragment. Here is an example.
class Mut{
static Mut Fido = new Mut();
Mut Sammy = new Mut();
public static void main(String args[]){
This piece of code will compile but when I run it on an WindowsXP machine the JRE tells me there is an exception at line 3. If I change the code to this:
class Mut{
static Mut Fido = new Mut();
static Mut Sammy = new Mut();
public static void main(String args[]){
The code runs fine without any problems. My question is: why can't I create a static object and a nonstatic object in the same class? Is this a certain feature of JAVA I don't understand or is this a blackbox problem with XP? Any help is appreciated. Thanks
VanceIs the exception stack trace what is displayed in the command-line window? If it is here is what is displayed(This is a lot):

Problem with writing and reading using serialization
I am having a problem with writing and reading an object that has another object in it. The purpose of the class is to write a order that has multiple items in it. And there will be several orders. This is for an IB project, where one of the requirements is to utilize a hierarchical composite data structure. That is, it is "one that contains more than one element and at least one of the elements is a composite data structure. Examples are, an array or linked list of records, a record that has one field that is another record, or an array". The code is shown below:
The error produced is

Problem with yosemite and parallels
Since I have upgraded to yosemite and parallels 10 my windows 7 has been using a lot of CPU resources. Windows 7 runs very slow and it been using almost constantly 100% of one of the quads resources. This just started to happen when I upgraded, because I did not have this problem with Mavericks and Parallels 9 or 10. I have an iMac 2011, 8GB of Ram. Has anybody had this issue. Thanks.
Thanks for the response. I was searching on a parallels forum website and found the following:
As from the symptoms, the issue can lie in NVRAM preferences of your particular Mac.
Please do the following to solve:
open Terminal application on Mac (Applications/Terminal.app)
please type this command (you may copy-paste it to the terminal from this message):
sudo nvram boot-args="debug=0xd4e"
Hit Enter.
You will be prompted to enter Mac user password. Please type it and hit Enter.
Note: you won't see what you are typing, just type and hit Enter. If you don't have Mac user password, please create a temporary one.
Then you may restart your Mac and the issue should be solved.
If not - please reply me here and I'll create a ticket for you in Support.
I did the above and it seemed to correct the problem. -
I have a problem with an update page on my website
Here's how it work
values are defualted in from the advert table - this works fine
I should then be able to change the fields and click on the update button
This works fine but ONLY when the O_year field is populated.
There doesn't seem to be anything special about the O_year field
I thought spry text validation would of been causing the issues, but I removed them and have the same problem.
For some reason the POST_MMupdate value is not being set to 'form4', which it is doing if O_year is set.
Please can someone have a look at this, code,
Also, is there a way of 'stepping through' dreamweaver code to debug it?
Thanks
Adam

Problem with JPanel.updateUI()
Hello,
i have a problem with updateUI(), here's a simple example what's wrong. just compile and run the following piece of code and look what happens after 2 seconds: the left panel will be decrease its width after calling updateUI(), but why? is it a bug of updateUI() or is it my fault?

i have a problem with updateUI(), here's a simple
example what's wrong. just compile and run the
following piece of code and look what happens after 2
seconds: the left panel will be decrease its width
after calling updateUI(), but why? is it a bug of
updateUI() or is it my fault?updateUI() its called when the L&F is changed, there is
rarely a case when you need to call updateUI().
Why do you call updateUI() if you remove the call to updateUI()
everything will work OK.

Problem with JTable and JPanel
Hi,
I'm having problems with a JTable in a JPanel. The code is basicly as follows:
public class mainFrame extends JFrame
public mainFrame()
//A menu is implemeted giving rise to the following actions:
public void actionPerformed(ActionEvent evt)
String arg = evt.getActionCommand();
if(arg.equals("Sit1"))
//cells, columnNames are initiated correctly
JTable table = new JTable(cells,columnNames);
JPanel holdingPanel = new JPanel();
holdingPanel.setLayout( new BorderLayout() );
JScrollPane scrollPane = new JScrollPane(holdingPanel);
holdingPanel.setBackground(Color.white);
holdingPanel.add(table,BorderLayout.CENTER);
add(scrollPane, "Center");
if(arg.equals("Sit2"))
if(scrollPane !=null)
remove(scrollPane);validate();System.out.println("ScrollPane");
if(holdingPanel !=null)
remove(holdingPanel);
if(table !=null)
remove(table);table.setVisible(false);System.out.println("table");
//Put other things on the holdingPanel....
private JScrollPane scrollPane;
private JPanel holdingPanel;
private JTable table;
}The problem is that the table isn't removed. When you choose another situation ( say Sit2), at first the table apparently is gone, but when you press with the mouse in the area it appeared earlier, it appears again. How do I succesfully remove the table from the panel? Removing the panel doesn't seem to be enough. Help is much appreciated...
Best regards
SchwartzIf you reuse the panel and scroll pane throughout the application,
instantiate them in the constructor, not in an often-called event
handler. In the event handler, you only do add/remove of the table
on to the panel. You can't remove the table from the container
which does not directly contain it.
if (arg.equals("Sit2")){
holdingPanel.remove(table);
holdingPanel.revalidate();
holdingPanel.repaint(); //sometimes necessary
}
