How can i extract system properties

how can i extract OS properties like desktop resolution, type of internet connection, sound capability, browser character settings etc. ??

type of internet connection,Not possible. You can detect the lack of an active
internet connection though (figuring out how is left
as homework for the reader;)),
sound capability,Nope.
browser character settings etc. ??Nope.
Tuomas RintaThanx for replying..
Are you serious ?? There is no way to check if the system is sound capable or not ? ok for the type of internet connection i thought that you couldn't so...
as for the existence of an internet connectio....i am not that new...

How can I get system properties?

Hello,
How can I get the system properties like %JAVA_HOME% in my java codes, for example, I want to print it like this.
System.out.println("%JAVA_HOME%");
but it doesn't work!
Please give me a hand!

To pass the Operating system environment variable to the Java "environment variables", you have to explicitely pass them on the command line eg.
java -Dmyjava.home=%JAVA_HOME% myClass
then, in your code use
String JAVA_HOME = System.getProperty ( "myjava.home" );regards,
Owen

HOW CAN I EXTRACT THE SYSTEM DATE?

HOW CAN I EXTRACT THE SYSTEM DATE?

import java.util.*;
import java.text.SimpleDateFormat;
public class date2{
    public static void main(String[] args){
        Date today = new Date();
        SimpleDateFormat output = new SimpleDateFormat();
        String answer = output.format(today);
        System.out.println(answer);
}If you want to make it prettier, you can look at using a locale, or a pattern string in the SimpleDateFormat constructor. Read the Documentation.
Note that new Date(), constructs a Date with the current Time,
you could also use: new Date(System.currentTimeMillis());
Hope this helps

How can I extract the data from Xstring .

Hi Gurus ,
How can I extract the data from a XSTRING .
I have to get the data which is filled in the survey form the data is getting saved in form of xstring .
Someone told me that there is a standard FM for that . but I am not able to find .
Please reply with the FM in case some one knows about it .
Thanks in advance .

The following code works as of 7.0 (in any SAP system):
FORM XSTRING_TO_STRING USING input TYPE xstring CHANGING output TYPE string.
TYPES : BEGIN OF ty_struc,
          line TYPE c LENGTH 100,
        END OF ty_struc.
DATA lt_char TYPE TABLE OF ty_struc.
DATA length TYPE i.
length = xstrlen( input ) / cl_abap_char_utilities=>charsize.
CALL FUNCTION 'SCMS_XSTRING_TO_BINARY'
EXPORTING
    buffer                = input
tables
    binary_tab            = lt_char.
CONCATENATE LINES OF lt_char INTO output RESPECTING BLANKS.
output = output(length).
ENDFORM.

It is a known problem on Microsoft's end.
From their site:

How can I extract ? Please help me.........

First of all, I am very new user to XML and also Java. If my question is nonsense, forgive me, please.
I would like to test that the string in the node are equal with some string that I want to search. I use DOM API.
The following code are ok for the node is directly included text CDATA. The program gives the true value. In the following simple code, I tried to search the string "ACTI".
for example; the node, <LABEL>Problem in Activity</LABEL> , I got "true".
But I would like to match also the node ,
<SLOT label="slot" kind="a/o" role="occurs in" class_constraint="Activity" >
There is also "Activity" string value in class_constraint.
So how can I extract and match that string data?
Help me please!
case Node.CDATA_SECTION_NODE:
System.out.println(node.getNodeValue());
if (node.getNodeValue() != null) {
     String aa = (node.getNodeValue().toUpperCase());
     if ( (aa.indexOf("ACTI") >= 0))
     System.out.println("true");
     else
     System.out.println("false");
<CONCEPT>
<LABEL>Problem in Activity</LABEL>
<SLOTS>
<SLOT label="slot" kind="a/o" role="occurs in" class_constraint="Activity" >
</SLOT>
</SLOTS>
</CONCEPT>

Thank you very much for your help.
I do appreciate your reply.
As I gave my code example in my first post, I parse the XML document and I checked each node whether it is CDATA Node or Document Node, Element Node, and so on.. I used CASE statement.
If it is CDATA node, I compare Node value and the string I want to search.
At that time, I faced the problem that you solved already, I didn't know how to compare in attribute node.
With your suggestion, I can compare now.
But the problem now is that... when I extract element by tag name, it cannot test node by node.
So, how can I combine these two code?
Actually, what I am going to do is that if node is not match (in anywhere) with the string what I want to search starting from parent node to all child nodes, I want to delete that node starting from parent node and it's childs. And I want to create a new XML document by deleating unmatched nodes.
For example, in the following XML, I would like to delete the second <CONCEPT> node while I search for "Acti" string. There is no "Acti" in the second.
<CONCEPT>
<LABEL>Problem in Activity</LABEL>
<SLOTS>
<SLOT label="slot" kind="a/o" role="occurs in" class_constraint="Design" >
<SUB_L label="" def="" role_name="" class_const="Activity" />
</SLOT>
<SLOT label="slot" kind="a/o" role="occurs in" class_constraint="Const" >
<SUB_L class_const="Activity" />
</SLOT>
</SLOTS>
</CONCEPT>
<CONCEPT>
<LABEL>Problem in REQ</LABEL>
<SLOTS>
<SLOT label="slot" kind="a/o" role="occurs in" class_constraint="Req" >
<SUB_L class_const="Change" />
</SLOT>
</SLOTS>

How can i extract using while the time from the string ?

First time how can i extract the time as string ?
And second how can i extract the time as DateTime.Now ?
public static void ExtractDateTime()
htmltoextract = new Uri("http://test.com");
client = new WebClient();
f = client.DownloadString(htmltoextract);
client.Dispose();
int index = 0;
while (index != -1)
int t = f.IndexOf(firstTag);
int g = f.IndexOf(lastTag);
a = f.Substring(t + firstTag.Length, g - t - 8);
The string look like this: thisisateststring201309202145andthenextimeinthestringis201309202130andthelastofthisexampletimeinthisstringis201309202115
What i need to do is first time to extract the time as string to a List<string> like this:
index 0 201309202145
index 1 201309202130
index 2 201309202115
The second time to extract the times as this time format: YYYYMMDDhhmm and also to add the times to a List.
First time and second time i mean first example and second example. To use my code but first time to extract it as strings second example as the format of YYYYMMDDhhmm
And i need to use the while and indexof and substring in this cases.

Is the region always going to be "eu" or are you going to have more than one region. Since you are reading a string DateTime from different timezone than the computer you are reading the data you have to convert to a different timezone.
It looks like you have at least 'is' and 'eu' for regions. I don't know what offsets you need so try something like this.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Text.RegularExpressions;
using System.Globalization;
using System.IO;
namespace ConsoleApplication1
class Program
static void Main(string[] args)
string input = File.ReadAllText(@"c:\temp\test.txt");
string pattern1 = @"imageUrls = \[[^\]]*\]";
Regex ex1 = new Regex(pattern1, RegexOptions.Singleline);
string pattern2 = @"region=(?'region'[^&]*)&time=(?'time'\d{12})";
Match match1 = ex1.Match(input);
Regex ex2 = new Regex(pattern2, RegexOptions.Singleline);
MatchCollection matches2 = ex2.Matches(match1.Value);
IFormatProvider provider = CultureInfo.InvariantCulture;
List<DateTime> dateTime = new List<DateTime>();
foreach (Match match2 in matches2)
string region = match2.Groups["region"].Value;
DateTime dt = DateTime.ParseExact(match2.Groups["time"].Value, "yyyyMMddHHmm", provider);
switch (region)
case "eu" :
dt.AddHours(1);
break;
case "is":
dt.AddHours(-1);
break;
dateTime.Add(dt);

How can i get system variable using java

Hi,
I just want to know how can i get system variables using java code.
for example i want to get the the date for today or i want to get the number of processes that's running.
Thanks alot

Hi,
I just want to know how can i get system variables
using java code.
for example i want to get the the date for today or i
want to get the number of processes that's running.
Thanks alotSome generic "system variables" are available though Java, usually through the System class.
Date today = new Date();
is instantiated with the current date and time.
Other system values, like environment values, should be passed to java through the command line (-D option) by setting system properties.
Finally, platform specific values like the number of processes running will have to be written in platform specific code and executed by JNI (java native interface).
Java is platform or system agnostic. Common system values, like time, are implemented. Hopefully you won't need platform specific values.

How can I extract only the audio as an aiff file?

Using a Sony DSC-N2 Cybershot Camera I recorded video that was saved as “MOV01606.MPG”. The video plays back with sound in Quicktime Pro and iTunes but how can I extract only the audio as an aiff file?

Use MPEG Streamclip (free) to convert your .mpg files to QuickTime formats.
QuickTime can't extract audio from muxed file formats.

How can i extract just documents from time machine backup?

How can I extract just my documents from a time machine backup? I had to re-install Lion after the update screwed things up, the Genius Bar guy told me to re-install each App, and then transfer just my data (documents) back but didn't tell me how. I only see how you can restore the entire snapshot of what was on my MacBook that day, I don't see how to select specifics.

Hi,
Install a fresh Lion OS on your Mac. After this is done, then connect your time capsule. Click on the time machine icon in the dock bar so you will enter in time machine. Select the document folder and any document or all you need. The same thing you can do with iPhoto, Emails, etc.
Let me know

How can I extract the two channels from a stereo track?

Hi,
I am writing a class that is able to draw an audio signal. It seems to be working well but I have a question. If I load a mono audio file I am able to draw it on a graph by using the byte[] array and everything is ok until now. That's the code:
void Draw(byte[] x)
            Graphics g=getGraphics();
            Graphics2D g2=(Graphics2D)g;
            g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,                     RenderingHints.VALUE_ANTIALIAS_ON);
            for(int i=0; i<x.length-6; i++)
                g2.draw(new Line2D.Float(((i*(getWidth()-6))/x.length)+5, (getHeight()/2)-          ((x*(getWidth()-6))/x.length), (((i+1)*(getWidth()-6))/x.length)+5, (getHeight()/2)-     ((x[i+1]*(getWidth()-6))/x.length)));
The results is correct only if I have a mono track. Obviously when I get a stereo track the array becomes very large so here the question. How can I extract the two audio channels from a stereo track?
Thanks in advance.
Maurizio Di Vitto

A mono audio stream is stored [sample, sample, sample, sample], so just a list of samples in an array.
A stereo sample is interleaved in the same manner, so you get [left-sample, right-sample, left-sample, right-sample]
So every nth sample is the 1st channel, every nth+1 is the 2nd channel...

How can I access the properties of Microsoft files (excel, ppt, and word)

Hi,
How can I access the properties of common Microsoft file formats (Excel, Word, and Powerpoint) from a Java program. You can access/modify the properties of each document type using File->Properties in each MS application. The properties are essentially name/value pairs.
Basically, I need to write a java program that scans a directory and accesses the properties in each of the MS files in the directory.
thanks,
-john

By api. That is only way to establish a contract with the MS programs you want to interface with, unless you write an api yourself! I've used POI and it was an awesome way to use Excel in java. I created an excel spreadsheet from the results of a sql query from a batch program and then it was automatically emailed using javamail to my client. I had a lot of VBA experience with Excel, Word, and Outlook and it didn't take me long to get used to using Jakarta-POI.
Now I see there is Jakarta-POI-HWPF which works with MS Word documents. Go to: http://jakarta.apache.org/poi/
