Swing was not part of any JDK's earlier than 1.2. Swing (or anything with a J in front of it, ie. JFrame, JOptionPane, etc...) was probably the most dramatic (if not largest) modification/addition to the Java language, that's why versions later than, and including, 1.2 are known as "Java 2".

Import javax.swing.* error

Heya. I decided to learn java and i've been doing the tutorials, recently i started the swing tutorials and the learn by example page. However, whenever I try to import javax.swing.* it gives me an error. SO you know, i am using the J2SDK 1.4.2 and netbeans IDE 5.0. Here's the error text and what i type.
import javax.swing.* ;
the error is:
illegal start of expression and then sometimes i get <identifier> expected.
can anyone help me?

To update. I figured out how to do this with a blank start file in netbeans, however it's awful to have to delete main and then make a new class file. So, is there anyway to get a blank template project or to import javax.swing.* without having to delete main and start with a blank file? SO, i guess my question has changed, but it's still about an import javax.swing.* error.
thanks.

I am using metrowerks and i get the same problem with
similiar code. I have J2sdk 1.4
what do you think is wrong?I don't have worked with Metrowerks before, so are you sure that the compiler doesn't have an own
JDK embedded (like JBuilder) ?
If this is the case, I don't know if you can select in Metrowerks an other installed JDK.

Can't use import javax.swing.RowFilter; in javafx

Dear all,
I'm a question for you.
I developed a javafx application in which I use also swing dialog and swingx libraries.
The question is I can't use jtable filter of java jdf 1.6
That is when I try to add in my netbeans javafx project
import javax.swing.RowFilter;
it says me it's not correct library
If I create a java swing application I can add this include.
Why it?
I edited netbeans conf to set javafx sdk to javafx lib I downloaded (whole sdk), not that one with netbeans, but nothing.
It seems like I can't use this import in javafx application.
Is it posbbile?
Please help me

The reason you cannot use it is because javax.swing.RowFilter was introduced in Java 1.6 . Netbeans compiles JavaFX to work with Java 1.5, which does not have the class in question.
I have gotten around this by going to the properties->Libraries->Add JAR/Folder menu and included the jre/lib/rt.jar file from the jre directly into my project.
Someone else posted a similar solution and more detailed explanation here: http://steveonjava.com/hacking-javafx-10-to-use-java-16-features/

Importing javax.swing.plaf.basic.BasicListUI.MouseInputHandler

Hi!!
I have totally no idea why I cannot import javax.swing.plaf.basic.BasicListUI.MouseInputHandler. The compiler says BasicListUI interface is expected.

Agreed (maybe even so for 1.4.1 that I've just wiped out so I can't cehck my old rt.jar :o).
For the moment I use my old translation of the basic.properties (and windods.properties) packed in a jar-file placed in
jreXX/lib/ext/myLanguage.jar
So far it works for the dialogs in my applications ...
However, I don't find this a clean solution. I now find basic.class in rt.jar. Juged from all the other basic_xx.class files in rt.jar I guess this is where basic.properties went ... My next move will be to get hands on the source code of JAVA and check out how basic.java looks like ... perhaps this is a class filled with static fields and a simple method that sets properties in memeory or ? or ? ... In particular I need find out if some 'fields' have been added or removed compared to the old basic.properties. If so, the old translation would only be parial and my apps would be a mix of danish and english.
I'm not really that much of a JAVA programmer and this is just to share some thoughts. Does anyone out there know a central reference on how those of us that speak minority languges easily get translations of core JAVA stuff (meaning Yes, No, Cancel and the like) take effect the easy way? Are there national boards that take care of such business?
Maybe I haven't searched enough for information - my apologies if you found it waste of time reading this reply.
With kind regards and thanks in advance, MJTJ

Import javax.swing problems

hey
I am new to java and have recently downloaded j2sdk1.4.2_04. I am trying to create a simple graphical application. However, It doesnt seem to import the javax.swing.* libraries. I understand that there is the src.zip in the directory, so I unzipped it but it still doesn't read the package. I read elsewhere on this forum that you should set the path to src.zip. I have tried that and it also doesnt work. My current path is:
PATH=C:\j2sdk1.4.2_04\lib\src.zip;C:\j2sdk1.4.2_04\bin
Is there an error in this, or what else should I try? All suggestions greatly appreciated.

There's no need to set your classpath when importing any of the standard packages that are provided by the JDK. Perhaps you could post a (small) code sample and the compiler error you are getting.

Java Performance. Importing javax.swing.*

Hi everyone,
I have heard several times that importing entire packages into an application (class) that only requires 1-2 classes from that package is a bad idea, most notably for performance reasons (as well as code engineering quality).
I'm wondering if someone can provide a concise and insightful reasons as to why this is the case. I'm currently moving a C++ application to Java (don't ask why!) and am looking at performance aspects.
Thanks

import statements tell the compiler where to look for the classes
so it is not a performance issue when the program is executing.
Also at compile time, the difference is insignificant compared to the
rest of the compilation.
As for code maintenance, I find that if I am using something from the
java.util package, then I specifically import it, like import
java.util.Vector. However, I genenerally import java.awt.event.*; and
javax.swing.* because it is easier.
I would worry about the architecture of your code more than import
statements!!

}

Yeah!!! It works. Turned out to be a combination of DrKlap's and Martisan's suggestions -- had to change var frame's declaration from JFrame to MyFrame:
    MyFrame frame;Next, created the external class -- but again changed JFrame references to MyFrame:
public class ShowOnExit extends WindowAdapter {
//   JFrame aFrame;
   MyFrame aFrame;
   public ShowOnExit(MyFrame f) {
      aFrame = f;
   public void windowClosing(WindowEvent e)
      System.out.println("Why me???" + aFrame.textArea.getText()); // aFrame here not frame !!!
}This worked. So looks like even though the original code added a WindowListener to 'frame', the listener didn't couldn't access frame's methods unless it was explicitly passed in as a parameter. Let me know if that's wrong.
Thanks again, all.

why? what's wrong? thanks

The DocumentParser seems to throw a ChangedCharSetException if it finds a "http-equiv" meta tag for "content-type" or "charset" and if the parser's "ignoreCharSet" property is set to false on creation.
