How to extract the size and date from a given file

Hi,
I want to extract the size and date of a file (it can be either a video, audio or text file) that the user points to the location of. But I am not sure how. Does Java have an api that can do this? If not is there some other way of doing this? Can anyone help? Thanks in advance.

Have a look at java.io.File, specifically
public long lastModified()
This format returned (I find) is nasty, so then use java.util.Date (or java.sql.Date, look the same on the surface to me) to format it.
Cheers,

How to extract register names & their addresses from .inc file of a microcontroller

Hi,
I want to extract register names to a dropdown and their corresponding addresses from .inc file in such a way that when I select a register from dropdown, it has to also show its address in a string indicator.
However, only a part of .inc file consists of register definitions and the rest has bit definition of registers (unwanted). How can I extract this using labview?
Attached is a sample .inc file for PIC18F4620 device.

Read the file line by line until you find "Register Files" (use for example Search/Split String).
Then, read again splitting each line in its tokens (use Scan String for Tokens).
Keep the first token as name and convert the proper substring of the third token to the address value.
Terminate when line is empty.

How to create package and import from jar file?

Hi all,
I am writing a software and I am not sure how to create a package for the classes.
Say I have two classes in the same directory as follows:
testA.java
==========
package AB;
public class testA
public static void main(String[] args){
     testB myB = new testB();
     System.out.println("A test");
testB.java
===========
package AB;
public class testB
public testB(){
     System.out.println("B constructor");
both file compile without the package heading;
both file compile using: javac -classpath .\ *.java
Question 1:
I cannot run testA by: java -classpath .\ testA
I think it is a syntax error. What is the correct one?
If I run testA by: java testA
The only output I get is: A test
But I am expecting: B constructor /n A test
What went wrong?
Question 2:
I need to use APIs of another software. I have downloaded a .jar file (xxx.jar) with all the classes in it. And I have put "import xxx.*;" in my source file. But the compiler complains about the importing. What is the right way to copmile it?
I have read a couple of tutorials but they don't answer my question.
(I am using windows2000 and don't have the classpath variable.)
Hope some one can help.
Thanks a lot

Try moving testA out of the package and importing 'AB.*;'
If you have:
./testA.class
./AB/testb.class
Then to execute testA from ./ type: java -cp . testA

Include text file and display from text file

Ok. I'm found the site with the monkey on the the flash thing and all it shows is a name, email and something else and I used it and it works by including a txt file and displaying text from that file as putting down this information
name.text = this.name;
and I can't find the site anymore to get help.
I want to know how to include a PHP script that shows this information like this
text=something I need&username=My Name&email=[email protected]
I want to show this stuff on the flash but every time I execute by using it as localhost/test.php, it will show a sentax error.
This is really stressing me out and I need a lot of help on this stuff.
Can someone help me?

ok. let me describe something else.
there's 3 text boxes that is dynamic text.
one of them is called name
the other one is called email
and last one is called location
in the text file, it shows this for importing to the flash file
name=My Name&email=EMAIL&location=My Location
When viewing the flash file that you created, it shows the name, it shows the email, and it shows location.
When I do it on my own even with a text file, it keeps on saying that there is an error on line 1.
I found a site that shows how to do it and it shows what to put in a text file, and it shows the action script. On the FLA file that he shows me has a monkey on the flash file and it has 3 text boxes that I described above. As well as the text file, it is the same. I used the example and it worked but I can't find the example again. I don't know what happened to the website and I don't know what happened to the download I had but it is not downloaded any more. I have adanced systemcare pro so it clears out my recent web searches and my recent downloads so I can't find it. I did a google search on anything about action scripts. I even did a monkey action script search and I couldn't find it.
It's making me mad and I don't know what to do. This is stressing me out way more than you think.
UPDATE:
I did a google search on a file I found in my www folder and I found it. finally.
Here's the site.
http://www.kirupa.com/developer/mx/externaldata.htm
now, I need to figure out how to load it from a PHP file.

Java Plugin and GIFs from Jar file...

This used to work and I haven't looked at it for a while. First thing I did is run the old java applet web page with the old jar file, kinda just to lay eyes on the thing again.
It had to download a new plug-in from Sun, and upon doing so, reports a new error indicating that the value for the cache_version attribute in the HTML is incorrect. It was 1.0 (always has been) and the plugin says it needs to be in X.X.X.X format instead.
So, that isn't a nice change to make in the plugin at this time. However, if I just click okay and close the error dialog, at least it works fine after that.
In my attempt to get rid of the dialog I change the cache version to 1.0.0.0, upon doing this
the toolbar images no longer load, it says there is a java.io.FilePermission error.
We'll it doesn't make any sense that a mere change to cache version caused that so I changed the version back to the apparently erroneous value of 1.0, and then the toolbar images work again ! But I get the permission error.
Any ideas how I can fix these pesky images loading from a jar ?
Do you have any code that loads images out of a jar in an applet succesfully ?
Or have any suggestions on what I could try ?
Below is the code I'm using to load the images, where icoXXXX is a ImageIcon object, and fileameXXXX is a string containing a relative file path such as "images/highcolor/toc_color.gif" (this code executes in the applet's init() method (called by the plugin):
java.net.URL urlToc = getClass().getResource(filenameToc);
java.net.URL urlTocBW= getClass().getResource(filenameTocBW);

dunno why but
getClass().$blah... wouldn't work for getting images in an applet from a jar for me.
But this does:
Class c = Class.forName("java.lang.Object");
InputStream in = c.getResourceAsStream("/images/myImage.gif");
byte[] buffer = new byte[in.available()];
in.read(buffer);
icon = new ImageIcon(buffer);
when included with the usual default exception handling.
Lemme know if that doesn't work for you.
cheers

Wl6.1, war files and 2 letter jar files....

Hi,I have finally found why my WAR file isn't loading with weblogic 6.1. It seems that it doesn't like two letter class libraries (eg ab.jar) and will through a vague error message at deployment (Prefix string too short). I don't know what has changed between 6.0.2 and 6.1 in this area, but its worth making it apparent to developers in general.Regards,Mark BarryHewlett-Packard Consulting

Are you saying that this error doesn't occur in 6.0?
I think i knew what's the problem is, but it would be helpful if you could post the stack trace?

How can i set the dos can compile and excute the jar file?please help?

How can i set the dos prompt can compile my .java file and execute my jar file.

Go to where you downloaded your Java SDK. Look around for a button labled "Installation." Click the button. Download the installation instructions. Read them. Then read them again.

New user...how do you drag or move or copy a file or folder from the desktop to an external drive? I have tried dragging and copy/pasting.

new user...how do you drag or move or copy a file or folder from the desktop to an external drive? I have tried dragging and copy/pasting.

My guess the problem you are running into is the drive is formatted for a PC as NTFS. OS X can read files from NTFS however it cannot write to it. Check the formatting on the drive, if it's NTFS then it should be reformatted to Mac OS Extended (Journaled), you can use Disk Utility to do this.
If you still have a PC and want to share the EHD with the PC and Mac please read MacWorld's Share an external drive between a Mac and a PC article.

How to extract HTML page from the internet

i am new to java, i wish to know how to extract Html page from the internet and also how to identify the differences between the images and text information?

You can create a java.net.URL that points to the file you want to "extract" and read the HTML code (or what ever that file contains) from there using the inputstream given by URL.openStream().
The difference between images and text... well, images are embedded in html using the img-tag. example: <IMG src="http://forum.java.sun.com/images/reply.gif" alt="Reply">. Attributes width, height, alt are sometimes left out and there may or may not be quotes around the values and everything is case insensitive... you'll be having hard time trying to parse the input so I'd suggest using existing parsers.
What are you trying to do anyway? You can load a URL directly to a JTextEditorPane with the setPage(URL page) method...

TS4153 few files and folder are not deleting from trash folder

i am trying to delete all files and folders from the trash folder by clicking empty securely, but its not deleteing the files anf folder. please suggest how to clean the trash folder by deleteing all the deleted files and folder.

Securely deleting items in Trash writes Zeros over the data so that it is completely eradicated.
This will take quit a long time depending on how much data you have in Trash.
Unless there is data that needs to be rendered unrecoverable in the Trash, you could choose to just delete the files and folders with out the secure option.
Once you have Emptied the Trash unsecurely you can always use disk utility to Securely Erase Free Space on the Drive.

How do you delete [empty] a single file or folder from "Trash"?

How do you delete [empty] a single file or folder from "Trash"?
Can you "securely delete" just 1 item?

A dangerous and incorrect shell command has been posted in this thread.
NEVER empty the Trash in the shell (Terminal.) NEVER put anything in the Trash unless you intend to delete it immediately. If you do put something in the Trash and change your mind about deleting it, move it out or use the Put Back contextual menu item. Then empty the remaining items in the Trash as usual.

Hi!
This is a possible solution to your problem.
import java.io.*;
class AddressExtractor {
 public static void main(String args[]) throws IOException{
 //retrieve the commandline parameters
 String fileName = "default.html";
 if (args.length != 0) fileName =args[0];
 else {
 System.out.println("Usage : java AddressExtractor <htmlfile>");
 System.exit(0);
 BufferedReader in = new BufferedReader(new FileReader(new File(fileName)));
 StreamTokenizer st = new StreamTokenizer(in);
 st.lowerCaseMode(true);
 st.wordChars('/','/'); //include '/' chars as part of token
 st.wordChars(':',':'); //include ':' chars as part of token
 st.quoteChar('\"'); //set the " quote char
 int i;
 while (st.ttype != StreamTokenizer.TT_EOF) {
 i = st.nextToken();
 if (st.ttype == StreamTokenizer.TT_WORD) {
 if (st.sval.equals("href")) {
 i = st.nextToken(); //the next token (assumed) is the '=' sign
 i = st.nextToken(); //then after it is the href value.
 getURL(st.sval); //retrieve address
 in.close();
 static void getURL(String s) {
 //Check string if it has http:// and truncate if it does
 if (s.indexOf("http://") > -1) {
 s = s.substring(s.indexOf("http://") + 7, s.length());
 //check if not mailto: do not print otherwise
 if (s.indexOf("mailto:") != -1) return;
 //printout anything after http:// and the next '/'
 //if no '/' then print all
 if (s.indexOf('/') > -1) {
 System.out.println(s.substring(0, s.indexOf('/')));
 } else System.out.println(s);
}Hope this helps. I used static methods instead of encapsulating everyting into a class.
