    How do I convert an int to a String?

    You can also use any of these methods if you need to get more complicated:
    Integer.toString(int i)
    Integer.toBinaryString(int i)
    Integer.toHexString(int i)
    Integer.toOctalString(int i)
    Integer.toString(int i, int radix)

  • How can I convert  an ArrayList to a String[]

    Hi,
    How can I convert an ArrayList (only with strings) to a String[] ?
    I've tried this :
         public static String listToString(List l) {
              StringBuffer sb = new StringBuffer();
              Iterator iter = l.iterator();
              while (iter.hasNext()) {
                   sb.append(iter.next().toString());
                   if (iter.hasNext()) {
                        sb.append(',');
              return sb.toString();
    But what I get is an array of xxxxx@435634 (for example).
    Thanks a lot !

    Strings are Objects but not all Objects are Strings and at least one of the elements in your List is not a String.

  • How can I convert/read out from a string Hex (8-bit), the bit 0 length 1

    How can I convert/read out from Hex (8-bit), the bit 0 length 1 (string subset!!??) and convert it to decimal.
    With respect to one complement and two complement ?

    Just like Jeff, purely guessing here.
    It almost sounds like you just need to Read from Binary File?
    AND the 8-bit number with 1?
    Need more details.  What exactly do you have to start with?  What exactly are you trying to get out of it?  Examples help.
    There are only two ways to tell somebody thanks: Kudos and Marked Solutions

  • How can I convert a Waveform to a String-For​mat?

    Hello,
    I write with "SQL-Execute.vi" datas to an Access-file. The "SQL-Execute.vi" needs a statement in String Format. And that is my problem. My source-datas (that I want to save to Access) are Waveforms. How can I convert the Waveform datas to a String Format?
    Thanks for help!

    Wire the waveform to the Get waveform componants function...from that you get t0, delta t and the sample values. Now you can generate whatever string you want based on that information...
    You could e.g. wire the Y array to a for-loop in which you calculate the time of each sample by taking t0 and adding delta t multiplied with the array index, then you could convert the Y value and the time to strings using the seconds to time string and number to fractional string functions...etc etc...

  • How can I convert date infomation to a string just includes the date not th

    I just want the date like Thu 08, july 2004 but not the exact time.
    how can I do that.

    The prior code produces a date formatted as Jul 7, 2004
    To get Wed 07, July 2004, try this minor modification:
    import java.text.DateFormat;
    import java.util.Date;
    import java.text.SimpleDateFormat;
    DateFormat format = new SimpleDateFormat("EEE dd, MMMM yyyy");
    Date mydate = new Date();
    String str = format.format(mydate);
    System.out.println(str);

  • How can i convert if the date in string format

    String lFstr = (String) pReq.getParameter("FND");
    String lTstr = (String) pReq.getParameter("TND");
    String lLstr = (String) pReq.getParameter("LWD");
    System.out.println(lFstr + " " + lTstr + " " + lLstr);
    //DateFormat ds = DateFormat.getDateInstance();
    DateFormat dateFormatter = new SimpleDateFormat("dd/MM/yyyy");

    lLdate = dateFormatter.parse(lLstr);
    } catch (Exception e) {
    System.out.println(lFdate+" "+lTdate+" "+lLdate);
    i am getting the values from request parameters at that time it is giving values.
    after convertion of string to date it is giving the null value what is wrong in this code

    It might have thrown an exception. Try printing the stack trace in the catch block.

    Hi,
    I guess the best way is to use regular expressions (must use SDK 1.4.1 or higher):
    Add the line:
    import java.util.regex.*;
    and use one of the methods:
    //Regex method to replace all \\t by <tab>
    public String replaceTabs1(String line, String tab) {
    Matcher matcher = Pattern.compile("\t").matcher(line);
    tab = matcher.replaceAll("<tab>");
    return line;
    //Regex method to replace \\t by <tab> one by one
    public String replaceTabs2(String line) {
    Matcher matcher = Pattern.compile("\t").matcher(line);
    while(matcher.find()){
    line = matcher.replaceFirst("<tab>");
    return line;
    Or, use more general method to find and replace any string by any other string in your file
    public String replaceText(String source, String find, String replace) {
    Matcher matcher = Pattern.compile(find).matcher(source);
    source = matcher.replaceAll(replace);
    return source;
    Hope it will work,

  • How can I convert an array off byte into an Object ?

    Hi folks...
    I�m developing an application that comunicates a PDA and a computer via Wi-Fi. I�m using a DataStream ( Input and Output ) to receive / send information from / to the computer. Most off the data received from him is in the byte[] type...
    How can I convert an array off byte ( byte[] ) into an Object using MIDP 2.0 / CLDC 1.1 ?
    I found on the web 2 functions that made this... but it uses a ObjectOutputStream and ObjectInputStream classes that is not provided by the J2ME plataform...
    How can I do this ?
    Waiting answers
    Rodrigo Kerkhoff

    There are no ObjectOutputStream and ObjectInputStream classes in CLDC. You must know what you are writing to and reading from the DataStream. You should write the primitives like int, String to the DataOutputstream at one end and read those in exactly the same sequence at the outher end using readInt(), readUTF() methods.

  • How can I convert a Database Handle from TestStand to LabVIEW?

    I want to use a Database Handle (already created in TestStand by an Open Database step) in a LabVIEW-VI (called from TestStand) to connect it with the "Connection Reference" input of the "Easy SQL.vi"? If I use a directly connection via the "TestStand - Get Property Value (Number).vi" I get back the error message 4101 in LabVIEW. How can I convert the Database Handle?
    Test Engineering
    digades GmbH
    www.digades.com

    The TestStand database step types use the CVI SQL Toolkit to talk to databases. The handle that you are referencing is an internal memory location and not a actual handle that you can directly use. Currently as implemented the handle that is stored in a numeric TestStand property for the connection and the SQL statement are the handle values returned from the CVI SQL Toolkit. So for the connection handle, you could call the CVI SQL Toolkit function
    DBGetConnectionAttribute (
    int Connection_Handle,
    tDBConnectionAttr Attribute,
    void *Value);
    and get the CVI CAObjHandle reference. With this you could then call the CVI ActiveX function
    CA_GetInterfaceFromObjHandle(
    CAObjHandle Object_Handle,
    const IID *Interface_Id,
    int Force_AddRef,
    void *Inte
    rface_Ptr,
    int *Did_AddRef);
    to get the actual ActiveX interface reference. This would have to be converted into a LabVIEW reference.
    You may want to consider just using LabVIEW to open a new parallel reference only using the toolkit.

  • How to convert an int variable into String type

    hi everybody
    i want to know how to convert an interger variable into string variable
    i have to implement a code which goes like this
    Chioce ch;
    for(int i=0;i<32;i++)
    // here i need a code to convert the int variable i into a string variable
    ch.add(String variable);
    how do i convert that int variable i into a String type variable??
    can anyone help me?

    Different methods:
    int a;
    string s=a+"";or
    String.valueOf(int) is the better option because Int.toString() generated an intermediate object to get the endresult
