So a basic question, you won't find any [i]polynomial[/i] library What is the probelm with the code you wrote ?

Show your code. Regular try/catch clause should do the job

And which code have you produced yet ?

> java Xyz where Xyz is the Xyz.class file generated by Netbeans

The garbage collector won't free objects that have still a reference. If it does, and the hell if I know how you figure that out, it is because your code does not have any more links to these objects. Unless you show your code, there is not much we can …

ArrayList are not synchronized while Vector are. No way Vactor will become obsolete. And yes you can use Vector of Vector. JTable use them

If you do not want to use standard Java JComponent and their look and feel why using Java ?

JComboBox inside JComboBox ? Never seen that before. I have seen cascaded combobox where selecting an item in the first one will change wat the other one shows but never what you mentionned. Anxious to see your code

You do nothing with number1 and number2 generated in your actionPerformed() You defined them there. may be you want: number1 = rand.nextInt(10); number2 = rand.nextInt(10); so it will affect your instance variables not the ones created in your actionPerformed()

Never heard of the SqlConnection() class usually use con = DriverManager.getConnection(dbPath + bdName, "sa", ""); And NetBeans has nothing to do with your problem/ NetBeans is just a fancy GUI editor no need to mention it in your topic title

JTextField.getText() will always return a String. I might have a length() of 0 but will never be null

If, for your application, a null String and a zero size String are equivalent you can: [code] if(a == null || a.length() == 0) { } [/code]

A char can always be converted to an int char x = 'z'; int i = x; as far as basic datatype are concerned you cannot apply a method to them so intLetter = charLetter.parseInt(); is obviously wrong

cronjob is Unix related java System.currentTimeMillis(); will give you the actual time in millis

We'll need mode details How do you import a picture into another picture ?

And please a more descriptive topic title "Help" is kind of a completly useless topic title in this forum

from System.out.println("\n" + var1,"\n" + var2); to System.out.println("\n" + var1 + "\n" + var2);

What have you tried ? Show your code

So obviously you are not entering integer if EasyIn works correctly

If you want to capture a keystroke it will be done through an ActionListener or a KeyboardListener or an EventListener of some kind all Java methods I am afraid off

make sure you put a System.out.println() statement in all your catch clause which will p[rint the error encountered

Your question does no make sense You miss some basic concept(s) How to configure my car to use shis racks while using a trailer ?

I'll bet your problem is somewhere else or you have a lot and lot and a lot of data in each of your pane. If it is the case, yes you can. Just add all your pane (JPanel I presume) empty Have a Listener to inform you when a Tab …

By default, in Swing, <TAB> means give focus to next component

just open the .html file find where the Applet is coming from FTP it back to yoyr local file system jad it

What in your terminoly is an "object name" tabbedPane.getSelectedIndex() will tell you which pane is visible

If each Tab has a JTextPane make an array of them then textPane[tabbedPane.getSelectedIndex()] will be the one in use

don't really see how you can import a .exe in Java will love to see the actual syntax of your import statement. Anyhow, if you managed to realize that exploit, for it to work in a .jar you will have to jar the .exe and use methods like getCodeBase() to …

Stay away from third parties software to do some basic operations like this one. Is your TerminalIO .jar file in your PATH variable ? If not, BlueJ must have, as all other IDE do, a place where you can specify external .jar to use. But as Akill10 mentionned, better to …

What do you have written up to now ? We will be glad to help you fix your bug(s) but we are not a code writting service.

You'll have to implement your own

Google wifi java

What does that have to do with Java ?

Syntax is since JRE 1.5 ArrayList<Customer> alCust = new ArrayList<Customer>(); In your Customer class your can have [code] class Customer { private ArrayList<Account> alAct; // constructor public Customer() { alAct = new ArrayList<Account>(); ... [/code] Happy coding

That is horrible code checking many times for the same condition at least make it that way [code] public boolean handleEvent(Event evt) { // handleEvent() if (evt.id == Event.WINDOW_DESTROY && evt.target == this) Checkers_WindowDestroy(evt.target); //window close action return super.handleEvent(evt); } if (evt.id == Event.ACTION_EVENT) { if(evt.target == newGameButton) { newGameButton_Action(evt.target); …

No difference

In which particular part of the assignment do you have a probelm ?

If this company respect the common Java standards which say that class name should start by a letter in uppercase and only lowercase are allowed in package statement the correct syntax would be: #import com.lowagie.*; to import all class of that package

Easier to write [code] class LinkedList implements Comparable<LinkedList> { public int compareTo(LinkedList other) { // no cast required return probability - other.probability; } } [/code] but as probability is a float better to [code] class LinkedList implements Comparable<LinkedList> { public int compareTo(LinkedList other) { return Float.compare(probability, other.probability); } } [/code] …

If it is a USB drive just like any other file from a regular hard disk.

As character everything > 255 will be registered in the file as String "?" which is decimal 63 hexa 3F bin 111111 so this is why when you read it back "?" it will be translated to 111111 unless your PC is configured with extanded Arabic/Kanji characters set

Avoid GUI builders. They generate human beings hardly understandable code. We can fix error(s) in the code YOU wrote but we cannot be behind you when you correctly/uncorrectly use the features of a GUI generator. Swing is really easy to use and when you will pass a Java interview and …

On a GUI application you can build a KeyEvent object with that sequence and send it to the keyListener of your JComponent listening for KeyEvent On a console application don't really see a way to implement that

ouf a lot complicated for nothing [code] ArrayList<Point> getPoint(String filename) { ArrayList<Point> al = new ArrayList<Point>(); Scanner scan = new Scanner(new File(filename)); while(scan.hasNextLine()) { String line = scan.nextLine(); String[] point = line.split(","); al.add(new Point(Integer.parseInt(point[0]), Integer.parseInt(point[1])); } return al; } [/code]
