Java syntax question.

other than in this example and similar
import java.util.*;can there be a . before a *?
I need to eliminate the bug in JRainbow that colors that * as an operator.

Hello
Can I post here(Acrobat Windows) Java Script questions here? If not, wht is the correct forum?
THank you

Back up and down to Acrobat Scripting. Bot Windows and MacIntosh Acrobat versions use the same JavaScript.
If you are using LIVECYCLE DESIGNER use their forums. The JavaScript syntax and objects are different in LIVECYCLE DESIGNER!

Java Syntax Analyser

Basically i am trying to make a java syntax analyser and there is one problem i am haing with the StreamTokenizer.
when the streamtokenizer reads a token it takes a whole string such as blah.blah.blah
but i want it to take on the first blah and then think that the '.' is a whitespace
is there any way of doing this.
also i tried using string.split(".") stuff but it seems that it regards the . as a termination character or something
can you answer some of these questions. thank you
regards
alpha

Oh, sorry, you asked for StreamTokenizer, not String Tokenizer. With Streamtokenizer, you can call
tokenizer.whitespaceChars('.', '.');
With that method, you can declare a range of characters as whitespace characters.

New improvement for Java syntax

Hi developers
I develop in java each day and the new project that I am envolved uses too much multithreading. So i thought that a litle improvement could be made on java syntax.
When two threads uses the same class attribute we must synchronize the access to this.
class myClass {
private int myAtribute = 0;
thread1: We must access the attribute synchronized....
shynchronized (this) {
myAttribute = 1;
thread2: The same....
synchronized (this) {
myAttribute = 3;
thread2: But if i don't care.... :-(
myAttribute = 4;
Ok, that is the problem.
I thought to solve this the java language must give us the chance to declare attributes in the way...
private synchronize int myAttribute = 0;
to be only accesed by sinchronized methods or by synchronized blocks in order to force interpreter to check if any method access this attribute without being synchronized in compiling time.

In your example, wouldn't the volatile keyword normally suffice?
private volatile int myAttribute = 0;Graeme

Flash/java remoting question

Hi,
i'm new to flash remoting and am finding using it with java
quite troublesome. I've also found using the FileReference class
troublesome if you use java. my question is can you somehow tie the
remoting functionality to the FileReference.upload method
fucntionality??
thanks in advance

I will use the program with photo detector to test
the response time of the LCD screenWhy Java?I second that. With a test like that, you want to reduce the experiment down to a single variable, in this case the lcd response time. Using a java program to feed the monitor input introduces a second variable, the response time of the program. The java program's timer may not be exact, the components may not be repainted completely quickly enough, etc. If this is just for your own amusement, maybe that doesn't matter, but if you want your results to have any reliability, you'll need a more accurate and controllable input source.

Java syntax in vim

can somebody help me set up correctly a java syntax in vim?
what files should be changed? it seems like the default syntax is for c/c++.
thx

try ":help syntax"

Java "Syntax" should be a main button.

So I really like the idea of the new syntax and such, but I think it's annoying that 1. I have to go to "advanced" reply to use "Java" syntax, and just having to click and scroll to it can be annoying(even though it takes 10 seconds.as it
ImO I loved being able to do {code}{code} as it was fast and easy, so something like that would be cool, or just having the little Java button on top. Is tables really more important than Java Syntax on a Java forum?
Thanks for the forum!

For a radio button group called 'frequency' where the value binding is
1 - weekly
2 - bi-weekly
3 - monthly
4 - annual
you could add the following client-side JavaScript to the 'frequency' change event.
var frequency = form1.subform1.frequency.rawValue;
switch (frequency) {
case "1":
form1.subform1.annual.rawValue = form1.subform1.pay.rawValue * 52;
break;
case "2":
form1.subform1.annual.rawValue = form1.subform1.pay.rawValue * 26;
break;
case "3":
form1.subform1.annual.rawValue = form1.subform1.pay.rawValue * 12;
break;
case "4":
form1.subform1.annual.rawValue = form1.subform1.pay.rawValue * 1;
break;
default:
break;

I'm currently only aware of JEdit and Netbeans being open source projects containing textarea components.

Why the JavaFX syntax not closer to the Java syntax?

I wonder why the JavaFX syntax is not closer to Java syntax than it is now?
For example why
public function myFunction(param: Integer): String[]
is not simply
public String[] myFunction(Integer param)
After all in JavaFX there is also the word Java :)

Somehow, I am more "shocked" by the usage of "script" name for JavaFX programs, since we don't really script an application (original sense of the word).It's certainly possible to have a long discussion about whether JavaFX Script is or is not a "scripting language". Unlike other scripting languages (e.g. JavaScript and Python come to mind, but there are many other possibilities) JavaFX Script is not interpreted directly nor is it dynamically typed. However, several features of the language do make JavaFX Script convenient for casual programming. For example, for simple programs it's not necessary to declare the types of variables, as they can (usually) be inferred by the compiler. Also, it's possible to code statements (really, expressions) "loose" in a plain file, without verbose class declarations. For example, "Hello, world!" in Java looks something like:
public class Hello {
    public static void main() {
        System.out.println("Hello, world!");
}whereas the equivalent in JavaFX Script is simply:
println("Hello, world!")For larger JavaFX Script programs one usually has to add import lines and class declarations, which do tend to lead away from the "scripty" feel of the language. Nonetheless I find JavaFX Script considerably more concise than Java and, well, the authors wanted to call it a scripting language, so there it is.
One other thing I learned recently is that to put something on the screen, it's not necessary to wrap your scene graph objects in a Stage and a Scene. If the last expression in the script is a Node, the runtime automatically provides a Stage and a Scene for you. So something like:
import javafx.scene.paint.*;
import javafx.scene.shape.*;
Rectangle {
    x: 50 y: 30 width: 100 height: 40 fill: Color.DODGERBLUE
}will work.

Simple Java Coding Question

I know this is a simple question, but I can't search for the answer to this because it involves syntax that Google and the like don't seem to search for..
I am trying to figure out some Java code that I have found. I would like to know what:
a[--i] and a[++j] mean.
My first thought was that they meant to look at the position in the array one less (or more) than i (j). But that doesn't seem to be the case. A is an array of Strings, if that matters...
Thanks for you help.

It mean increase/decrease the int i/j by 1. This is done before it gets you the value of a[]. for example if i=5 and you said a[--i] it is really a[4] and i is now equal to 4;

Simple Java EJB question.

When it comes to EJB v3 Remote and Local interfaces,
(With JBoss EJB Container Software in mind, for this question,)
-Does the Remote interface for the EJB include method signatures from the Bean class
-that are to be seen
-that are to be hidden?
-Does the Local interface for the EJB include method signatures from the Bean class
-that are to be seen
-that are to be hidden?
Which is which for
-EJB 2.1 ?
-EJB 3.x ?
- is EJB 3.x reverse compatible in that it allows use of the javax.ejb.* interfaces,
and would accept a EJB 2.1 approach, or does it force one to use Annotations
exclusively?

Plzzz write prog to this simple java threads question

Write a program in C to create four processes. The original processes creates
two children before it prints out "PARENT". The children processes print
"CHILD1" and "CHILD2" respectively. The first child process creates a child
process that prints out "GRANDCHILD".
Note: The output must be guaranteed to print out in the following order each
time it is executed:
GRANDCHILD
CHILD2
CHILD1
PARENT
a. Write the program using C or C++ and forks to create the children processes.
b. Write a second program using Java and Threads for the children processes.
The output statements for CHILD1, CHILD2 and GRANDCHILD must come from print
statements in the run method of the thread.

Most people here will not do your homework for you. If you post a reasonable question that shows you've made some effort, and what the results of that effort were, and provides details about what parts you're having trouble with, then somebody will probably provide guidance so that [you can complete the work.

Simple Java Sound Question...

Can I draw waveforms while capturing data? If yes, how. If no, why.
Thanks. I need the answer ASAP, please help.

Hi nfactorial,
Can I draw waveforms while capturing data?If you would like to do that in Java you would need to know about how to use the Java language in general and especially about the Java Sound and Java2D APIs.
If yes, how.It would be too much to explain to answer such a general question. A general answer is, you need to use the Java Sound API to capture the data for which a waveform should be drawn. The Sound API delivers data as a stream of bytes typically encoded in pulse coded modulation (PCM) format. The data stream has digital samples each representing a level of sound pressure for a certain point in time. The stream of samples in the amplitude/time domain need to be transformed to a spectrum of samples in the amplitude/frequency domain, i.e. a number of PCM samples need to be mapped to the frequencies that should be displayed. This is done with the fast fourier transformation algorithm. Each set of amplitude/frequency values can then be displayed as a waveform by using some line drawing logic. The entire process would need to run constantly, i.e. as bytes are received from the sound data stream transformation and drawing is triggered.
