How to get numbers out of a String?

Hi,
I have a string which is like that
"T,2,4,18,2,8"
and I need to get the numbers and use them as doubles.
How can I do that?

List doubleList = new ArrayList();
for (StringTokenizer t = new StringTokenizer("",", ");t.hasMoreTokens();) {
try {
doubleList.add(new Double(t.nextToken()));
catch (NumberFormatException ex) {}
}

How to get data out of XML?

Hi,All.
I am running SAX (JAXP1.01) in Applet to process XML file. My question is how to get data out of xml format according to the field name (@age,@rank etc)
and write into string buffer seperated by comma.
Should I use SAX or DOM? (file size is big)
My xml as follow :

For big files use SAX: quicker and less memory usage.
The xerces parser from Apache has some examples. Basically what you do is scan the XML, remembering what tag you are and once you find the right tag, read the contents.

How to Get In & Out of Match, Get your Downloads and Run

How to Get In & Out of Match, Get your Downloads and Run
So you have read the marketing hype, and are thinking what you really want is to pay for the service to upgrade your low quality bitrate files to a bit better 256KBPS rate easily, as don’t fancy rebuying/ reimporting or other method
This guide should show you the fastest route to achieve you upgrades
It assumes you’re working from your main music library, and know something about IT, and have <25k of music files
Backup your music files
If you know how to do this, its simple right – so once done then move to step 2, if not read below so you don’t blame me for a loss
Transfer Hardware
your choice the transfer hardware, suggest offline harddrive via USB3.0 (blue USB connector/eSata/ 1494b/1GB NIC/etcetera but your call
If you use USB2.0/ 100MB NIC/1394a or other lower transfer method, accept the time hit
Don’t use Time Backup/local disk backup software unless you have RAID 5 setup or better (and if wondering what that is, you almost certainly don’t then)
Don’t use internet backup service unless you live next door to the hosting company, with stunning internet connection to envy 99.9% of the human race, remember this is the fast method folks)
Transfer Software
I am assuming you know how to do a copy n paste/ robocoby/xcopy/drag n drop or whatever method turns you on via finder/explorer/cmd window ect
Caveat #01: If not sure how to do above, then stop now as you are not IT literate ready for this
Find your music files and back them up
Now keep the computer running, preferably with nothing else running from this point for ease of use bar an active internet connection, and power saving switched off
If you know where the files are great, backup the files, but some don’t so for them as below
Caveat #02: if you don’t know how to find them your most likely on default settings, or sitting with a legacy from a past upgraded machine - below should help but you might want to stop now if you have never been curious about the location before
Within iTunes , go to [Edit/Preferences/Advanced] and note down the location shown for Itunes Media Location
In the same location of preferences, hit [Keep iTunes Media Folder organised] and let the application do its stuff. You will end up with the location in 1ciii a ready to copy location which for simplicity of topic, copy the whole folder and its subfolders. You may end up with some extra copies of music files (an iTunes safety mechanism, but it won’t show in the folder location, and we can ignore later on)
Enable Match (after paying for the service)
Run Match
Accept that the Apple iTunes process is not perfect, may crash/stop/pause and reboots will be needed, and we can move on so to speak. Key here is you cannot do an unattended script or assume no end user interaction needed L
Turn on iTunes Match, notice the new ITunes Match on the left hand sidebar, click it, then hit the Start button – if it works and you eventually get to STEP 3 perfect.
If it fails before getting to STEP 3, reboot and restart
If this still fails to get to STEP 3, then create a new iTunes database (browse forums on how to do), read your media files from the location in 1civ
Stop MATCH (the upload process only, not the service)
Once STEP 3 starts, CLICK STOP - ASAP, as all this does it upload data, and you don’t want to do this, just get your upgraded files (remember the title of this entry your reading!)
This also avoids future issues with Album art lost
Delete Matched low bitrate files
Create a NEW SMART playlist, with two criteria
Show all files with bitrate is less then 256
Show all files where iCloud status is MATCHED
In the new playlist, click it and it shows the files we want to blow away.
Click Edit / Select All then
Click ctrl in windows/apple (cmd) logo in mac, and press delete button, ensuring you do NOT tick the delete from iCloud Option. Now want a few mins for it do do its stuff.
Download Upgraded BitRate Files
In the same location as 5, reselect all, and right click, and select the option to download all, and off it goes
On the lefthand sidebar in iTunes, click Downloads, and you will then see in the middle bottom screen an option for simultaneous downloads (select it)
Your done Just let the app now do its stuff. I would ignore the message saying you can get on with other things, and use anther machine, preferably not using the same internet connection.
Optional Steps:
Click randomly from the Itunes/Matched/256KBPS listed files, and play them. Not all the files, one every 30 or so, and just the start, then last few seconds to check not dead or corrupt files.
Update your Step 1 backup with the new files, which is going to take up more space, guess at 40%.
Kill your iTunes Match account (both the recurring automatic subscription, and the account if not continuing to use the store part of iTunes)

My 4gb SDHC flash mem card is stuck in DVD slot on my iMac 27". How to get it out?

I misplaced my 4GB flash memory card (Canon camera) in the DVD slot (above the card slot) and it disappeared while I was trying to get it out. Naturally I inadvertently (spelled "stupidly") knocked it inside and could not figure out how to get it out. The dust rubber "shields" hide it and I've tried to find it with a toothpick and wedge it out, to no avail. Are there any ideas or suggestions others may have used to get it out (I know turning it on it side and shaking won't work). Why in the world did they design it like it is -- I've had it happen to me and others have also told me of their misadventures, but they also were able to gradually get it out. This time, it's in too deep. Can I ignore it and still use the CD/DVD slot without it blowing up?

You might need to take to an Apple technician or apple dealer to let them take apart the iMac and remove the flash memory card. if you're very careful you might try a pair of needle nose pliers and a flashlight but it's easy to do damage to the DVD internal mechanical if you're not real careful.
A good story to tell your grand kids maybe ;-)
Good luck

How to get grainiesss out of black or dark areas?

you can't.
a) too low light recording results in 'noise' due to in-camera amplification
b) noise is handled by the compressors as 'content'; which results in blocky artefacts.

Please Help!! How to get the width of the String for print out?

Hi there,
I need to do some printing in my application. I just want to know how can I get the width of the string when it is printed on the paper.
I have tried to use the following code to get the width
Rectangle2D rec = font.getStringBounds(str, new FontRenderContext(null, true, true));
double width = rec.getWidth();
however, the width I got from that function is not correct (the returned width is longer than the printed one)
Does anyone know how to solve this problem?
Thank you and Happy New Year !

hi,
The getFontMetrics(Font) is also defined in the Component class and therefore you can retrieve it even if you dont override the paint method.
try the following (provided ur code extends some class that extends Component indirectly)
FontMetrics f = this.getFontMetrics(this.getFont());
int width = f.stringWidth(str); //str is the String for which u need to check the width.
hope this was useful
happy holidayz

How do i get numbers out from my ipod withouth having it

i dont have my ipod touch but i want to know if i can get numbers without having it on me

If you mean documents in the Numbers app then yes if you created an iCloud account and the iPod was signed into the account. In that case on a browser go to icloud,com, sing in and go to iWork then click on Numbers in the upper center.. You can download Pages, Numbers and Keynote documents by right clicking on the document and selecting Download.

ADF7,
I'm not sure I understand what you are up to.
As far as I understand you want to get the display value instead of the index
I use this code
    public void StatusChangedListener(ValueChangeEvent valueChangeEvent)
        BindingContext lBindingContext = BindingContext.getCurrent();
        BindingContainer lBindingContainer = lBindingContext.getCurrentBindingsEntry();
        JUCtrlListBinding list = (JUCtrlListBinding) lBindingContainer.get("Status");
        int newindex = (Integer) valueChangeEvent.getNewValue();
        Object row = list.getDisplayData(); // Wichtig um die liste zu laden!!!!
        Row lFromList = (Row) list.getValueFromList(newindex);
        Object lAttribute = lFromList.getAttribute("Value");
        String newVal = (String) lAttribute;
    }to get the value from a selectOneChoice component...

How to get the system date format string?

Hello, everybody!
I want to create a MaskFormatter with a mask for dates. So, I could suply as the constructor parameter: "##/##/####'. However, what if the year comes first in the current system date format settings, or the month is in the second place or in the first?... So, I can't just suppose that the current locale format for dates is like the one above. So, my question is: is there a way to get the SYSTEM DATE FORMAT STRING in Java? Searching in google I saw that this was already asked in this forum:
http://forum.java.sun.com/thread.jspa?threadID=301034&messageID=1193794
but there was no effective answer. Does someone already know how to get this?
Thank you.
Marcos

Hi, not sure, but
import java.text.*;
SimpleDateFormat sdf = new SimpleDateFormat();
System.out.println(sdf.toPattern());
will output something like dd/MM/yy HH:mm
hthThank you very much. It worked.

How to get the postion of any string

hi
like untitle.txt
how to get the postion of '.'.
Amit

Hi Amit,
Use SEARCH statement to find out a character or a string in a string.
DATA V_STRING TYPE STRING VALUE 'untitle.txt'.
SEARCH '.' FOR V_STRING.
If search is successful then it will return position of character or string into system field SY-FDPOS.
If your idea is get values of filename and extension by separating period then use simply SPLIT statement.
SPLIT V_STRING AT '.' INTO V_FILE V_EXT .
Thanks,
Vinay

How to get data out of Vector of vector ???

All,
I have a vector v1 which is getting populated by the resultset of the database. This vector has another two vectors vrow & vcol .
Code as follows ---
v1 = new Vector();
while(rs1.next()) {
     Vector vrow = new Vector();
     for (int i=intstartday ; i <= intendday ; i++)
     {     // here I am getting the new result set for each i //
          ResultSet rs2 = getResultSet();
          while(rs2.next()) {
               Vector vcol = new Vector();
               vcol.addElement(rs2.getString("day"));
               vcol.addElement(rs2.getString("reg_hr"));
               vcol.addElement(rs2.getString("dateday"));
               vrow.addElement(vcol);
          rs2.close();
     } // for loop end
     vrow.addElement(strChargeNmbr);
     v1.addElement(vrow);
} // end of rs1 resultset while loop
I need to get the data out of this vector v1. If anyone has any insight on this - how to get the data from vectors which has differnt type of objects in it , please send me the code example asap.
thanx

Thanks for your suggestion. It is working now except that I am having problems in getting the charge NUmber out....Charge NUmber is nothing but a String.
So my row Vector has two values
1. Check the code where I am populating the Vectors
while(rs1.next()) {
strsubmittime = rs1.getString("SUBMIT_TS");
strapprovetime = rs1.getString("APP_DIS_TS");
strapprempid = rs1.getString("APP_DIS_EMP_ID");
strChargeNmbr = rs1.getString("entered_cn");
Vector vLaborrow = new Vector();
for (int i=intstartday ; i <= intendday ; i++)
// here execute the query and get the result set for every i //                         ResultSet rs2 = getResultSet();
     while(rs2.next()) {
     Vector vLaborcol = new Vector();
     vLaborcol.addElement(rs2.getString("day"));
     vLaborcol.addElement(rs2.getString("reg_hr"));
     vLaborcol.addElement(rs2.getString("dateday"));
     vLaborrow.addElement(vLaborcol);
} // for loop end
vLaborrow.addElement(strChargeNmbr);
vLabor.addElement(vLaborrow);
} // end of rs1 resultset while loop
2. check out the following code where I am trying to get the Charge NUmber values out.--
for(int i=0;i<vLabor.size() ;i++)
Vector rowVec = (Vector)vLabor.elementAt(i);
for(int j=0; j< rowVec.size() -1 ; j++)
try
     if (j==0) {
String strChargeNmbr = (String)rowVec.elementAt(j) ;
Vector laborcol = (Vector)rowVec.elementAt(j);
String day = (String)laborcol.elementAt(0);
String reg_hr = (String)laborcol.elementAt(1);
String dateday = (String)laborcol.elementAt(2);
strChargeNmbr = strChargeNmbr + " " + reg_hr ;
}catch(ClassCastException e){
     System.out.println("Reading in vector2");
} // end of j for loop
System.out.println(strChargeNmbr);
} // end of i for loop
I am getting the following Exception --
"Reading in vector2"
Please send me the code -- how to get the Charge NUmber out. I am confused where to get the value - is it in the first for loop or second for loop ??

How to get two out param which is used in Procedure

hi experts,
Am keep on thinking, but not yet answer myself.. so am here
Using Jdev11.1.1.5.0-adfbc.
I had in db, procedure like this
PROCEDURE proc_find_x_cal_year_period
     p_bu                    VARCHAR2,
     p_date                    DATE,
     p_year           OUT          NUMBER,
     p_period             OUT           NUMBER
).................i wrote like this in My AM, Procedure is execution and printing out param values Perfect
    public void ProcFindxCalYearPeriod(String pbu,
                                    oracle.jbo.domain.Date pdate)
            CallableStatement st = null;
            try{
            String sql = "begin proc_find_x_cal_year_period" +
                "(:pbu," +
                ":pdate," +
                ":pyear," +
                ":pperiod)" +
                ";" +
                "end;";
            st=getDBTransaction().createCallableStatement(sql,this.getDBTransaction().DEFAULT);
            st.setObject("p_bu",pbu);
            st.setObject("pdate",pdate);
            st.registerOutParameter("pyear",Types.VARCHAR);
            st.registerOutParameter("pperiod",Types.VARCHAR);
            st.execute();
            System.out.println("pyear" +(String)st.getObject("pyear"));
            System.out.println("pperiod" +(String)st.getObject("pperiod"));
            catch(SQLException e)
            throw new JboException(e);
            finally
            if(st!=null)
            try{
            st.close();
            catch(SQLException e){}
            }what i did/my need:
i paste this ProcFindxCalYearPeriod in my one of the Eo and while am validating one of the field,this procedure should call at the time of calling, two out parameters set into two of the corresponding setter methods.
(String)st.getObject("pyear")
(String)st.getObject("pperiod")value is here i want to set into setAttributeInternal("x",(String)st.getObject("pyear") );
setAttributeInternal("x1",(String)st.getObject("pperiod") );
i hope you all understood.

In your procedure you should create an object to hold the outputs and return this object
public ProcResult ProcFindxCalYearPeriod(String pbu, oracle.jbo.domain.Date pdate)
            CallableStatement st = null;
            try{
            String sql = "begin proc_find_x_cal_year_period" +
                "(:pbu," +
                ":pdate," +
                ":pyear," +

            st=getDBTransaction().createCallableStatement(sql,this.getDBTransaction().DEFAULT);
            st.setObject("p_bu",pbu);
            st.setObject("pdate",pdate);
            st.registerOutParameter("pyear",Types.VARCHAR);
            st.registerOutParameter("pperiod",Types.VARCHAR);
            st.execute();
            System.out.println("pyear" +(String)st.getObject("pyear"));
            System.out.println("pperiod" +(String)st.getObject("pperiod"));
            //assuming that you are getting the desired outputs
            *ProcResult outputs=new ProcResult();*
            *outputs.setOutParam1((String)st.getObject("pyear"));*
            *outputs.setOutParam2((String)st.getObject("pperiod"));*
            *return outputs;*
            catch(SQLException e)
            throw new JboException(e);
            finally
            if(st!=null)
            try{
            st.close();
            catch(SQLException e){}
            }Now you call this procedure like this
ProcResult execProc= ProcFindxCalYearPeriod(paramValue1, paramValue2);
//you can get the proc outputs by calling
String firstOutput = execProc.getOutParam1();
String second = execProc.getOutParam2();But the question is why you are calling setAttributeInternal() while you are validating an attribute?
I think this is not correct.
