Greetings

I would like to change the LAF of my app

UIManager.setLookAndFeel("javax.swing.plaf.metal.MetalLookAndFeel");

which can be similarly achieved by the command line switch,

java -Dswing.defaultlaf=javax.swing.plaf.metal.MetalLookAndFeel MyApp

is working fine. My question is, is there a similar switch that set undecorated to false?

JFrame.setDefaultLookAndFeelDecorated(true);

Of late I have been bombarded about JDK 7 left, right, up, down and center. A search on the www isnt giving me much info as to what I would like to know - Apart from being able to perform sorting much faster than 6, what advantages do I have of choosing JDK7 over JDK 6?

I have seen some books write

Connection connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/test?", "", ""); //Note the ?

while others write

Connection connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/test", "", ""); // No ? Here


I was wondering which is better and why? What does the ? do?

Having followed the example given at http://www.zentus.com/sqlitejdbc/ I was able to run it successfully. A little modification however:
while (rs.next()) { System.out.println("name = " + rs.getString("name")); System.out.println("job = " + rs.getString("occupation")); } System.out.println(rs.getMetaData().getColumnCount()); // <- MODIFIED rs.close(); conn.close();
Throws this Exception:
Exception in thread "main" java.lang.IllegalStateException: SQLite JDBC: inconsistent internal state at org.sqlite.RS.checkCol(RS.java:62) at org.sqlite.RS.getColumnCount(RS.java:319) at workshop.Test.main(Test.java:53) Java Result: 1
I have Googled around but no fix I find. Any help please?

Thanks Rob. A little modification and all is OK

File file = new File("/"); URL[] urls = { file.toURI().toURL() }; ClassLoader loader = new URLClassLoader(urls); final File localeFile = new File("/etc/ussd/grouptext/MessagesBundle"); Locale currentLocale = new Locale("en", "US"); ResourceBundle messages = ResourceBundle.getBundle(localeFile.getPath(), currentLocale, loader); System.out.println("Loaded locale file OK"); System.out.println(messages.getString("groupcreatedsuccess"));

Hi Friends,

I have a problem when I try accessing a locale file from an absolute path.

I have this code:
final File localeFile = new File("lang/MessagesBundle"); currentLocale = new Locale("en", "US"); messages = ResourceBundle.getBundle(localeFile.getPath(), currentLocale); System.out.println("Loaded locale file OK");
It works well because I have the locale file as part of the packages of the application.

However,
final File localeFile = new File("/etc/ussd/grouptext/MessagesBundle"); currentLocale = new Locale("en", "US"); messages = ResourceBundle.getBundle(localeFile.getPath(), currentLocale); System.out.println("Loaded locale file OK");
brings out this problem:
Exception in thread "main" java.util.MissingResourceException: Can't find bundle for base name /etc/ussd/grouptext/MessagesBundle, locale en_US at java.util.ResourceBundle.throwMissingResourceException(ResourceBundle.java:1521) at java.util.ResourceBundle.getBundleImpl(ResourceBundle.java:1260) at java.util.ResourceBundle.getBundle(ResourceBundle.java:787) ... Java Result: 1
Any help please?

Indeed -- many people consider this a defect in the language specification. Some compilers -- Eclipse's Java compiler is one -- will warn you about this.

NetBeans also warns that

[finally] finally close cannot complete normally

Between

private boolean foo(String name) { return name.equalsIgnoreCase("myName"); }
and
private boolean foo(String name) { return name.equalsIgnoreCase("myName"); }

which one is it that we are to use? Javaranch says the former, many examples from Sun show the latter

Thanks! This is what I wanted:

String newWord = JOptionPane.showInputDialog(null, "Please enter the New Word", "My Old Word");

Maybe I didn't communicate appropriately. let me use diagrams then.

See the attached figure. When the input dialog is initialised, it displays as in fig 1. My wish is to have it display as fig 2 UPON INITIALIZATION.

Hi friends,

How does one set a value of a JOptionPane's inputDialog to have a preset String in the input?

This code:

String newWord = JOptionPane.showInputDialog(null, "Please enter the New Word", "Test Application", JOptionPane.PLAIN_MESSAGE);

Displays the dialog correctly, but I would like the field to bear the old word as a preset string.

Ok, Here is my terminal output:

I now face this problem; The progress bar does not gradually update, but instead "hangs" till the updating gets to 100%, then it shows 100%

This is the updated code:

public static void updateProgressBar() { long downloadedSize = updater.getSizeOfDatabase(); long totalDownloadSize = updater.getSizeOfUpdate(); int downloadedInInt = (int) downloadedSize; int totalInInt = (int) totalDownloadSize; System.out.println("Downloaded : " + downloadedInInt + " out of " + totalInInt); int percentage = (downloadedInInt * 100) / totalInInt; System.out.println("Progress: " + percentage + "%"); progressBar.setString(percentage + "%"); progressBar.setValue(percentage); progressBar.setStringPainted(true); }

Thanks a million for the clarification, Joanne. That has worked.

Am making an application that downloads updates from the Internet. It should update a JProgressBar appropriately as the download proceeds. There is the point of interest:

/** * Updates the progress bar with how much of the update has been got */ public static void updateProgressBar() { File copy = new File(originaldb); long downloadedSize = copy.length(); long totalDownloadSize = updater.getSizeOfUpdate(); int downloadedInInt = (int) downloadedSize; int totalInInt = (int) totalDownloadSize; System.out.println("Downloaded : " + downloadedInInt + " out of " + totalInInt); int percentage = (downloadedInInt / totalInInt) * 100; System.out.println("Progress: " + percentage + "%"); progressBar.setString(percentage + "%"); progressBar.setValue(percentage); progressBar.setStringPainted(true); }

Here this is the output:

Please, but why is it stuck at 0% then jump t0 100% yet the gradual progress is clear? Why doesn't it update?
