Just convert the strings to e.g. BigDecimal, then
round them, and convert back to string.
Kaji have tried with this code but i got error that bigdecimal we cannot pass String array so that i asked u.......
BigDecimal gridQty = null;
gridQty = new BigDecimal(arrQty);
gridQty = gridQty.setScale(2,BigDecimal.ROUND_HALF_UP);
arrQty = gridQty.toString();
System.out.println("Ramesh gross :"+gridQty);

    Can any body tell me How to store string array in a array

    YesNot quite sure what question you're answering but here's how to copy an array.// given a String[] strArr
    // pre Java 6
    String[] newStrArr = new String[strArr.length];
    System.arrayCopy(strArr, 0, newStrArr, 0, strArr.length);
    // post Java 6
    String[] newStrArr = Arrays.copyOf(strArr, strArr.length);Edit:
    Or in fact use clone() as mark pointed out.

  • How  to Pass String array from Java to PL/SQL  and this use in CURSOR

    hi,
    I cant understand how to pass Array String as Input Parameter to the Procedure and this array use in Cursor for where condition like where SYMPTOM in( ** Array String **).
    This array containing like (SYMPTOM ) to be returned from the java to the
    pl/sql (I am not querying the database to retrieve the information).
    I cannot find an example on this. I will give the PL/SQL block
    create or replace procedure DISEASE_DTL<*** String Array ***> as
    v_SYMPTOM number(5);
    CURSOR C1 is
    select distinct a.DISEASE_NAME from SYMPTOM_DISEASE_RD a
    where ltrim(rtrim(a.SYMPTOM)) in ('Fever','COUGH','Headache','Rash') ------- ***** Here use this array element(like n1,n2,n3,n4,n5..) ******
    group by a.DISEASE_NAME having count(a.DISEASE_NAME) > 3 ----------- ***** 3 is no of array element - 1 (i.e( n - 1))*****
    order by a.DISEASE_NAME ;
    begin
    for C1rec IN C1 loop
    select count(distinct(A.SYMPTOM)) into v_SYMPTOM from SYMPTOM_DISEASE_RD a where A.DISEASE_NAME = C1rec.DISEASE_NAME;

    Please give the proper solution and step ..

    I've haven't properly read through your code but here's an artificial example based on a sql collection of object types - you don't need that, you just need a type table of varchar2 rather than a type table of oracle object type:

  • How do I display array values in a text field?

    Hi there-
    I have a small Flash movie I'm trying to complete, it's my
    first go around with Flash 8 so I appreciate your patience:
    I built an array with some actionscript which seems to work
    fine (I can trace it and all is well in the trace window). Now I'm
    simply trying to display it to my Flash movie screen and I've built
    a dynamic text window which is working, except that I only ever get
    the last array element to appear in the dynamic text window. I've
    traced the code and see all of my array values, but when I use
    "myResults_txt.text=picker_array;" I only see the last position's
    value in my array. I tried playing with the "multiline" attribute
    for the text field, it didn't seem to make any difference.
    I'm sure it's probably something silly that I've missed, but
    how do you display an array, with all of it's values to a dynamic
    text field (I even tried using the textArea component but ran into
    the same problem).
    Thanks in advance for any help-
    rich

    Thanks for your input. I tried just about everything but
    ended up re-writing the contents of the array to a var and looping
    through the var. Not my first choice but it got me to done.
    Thanks again,
    Rich

    how do i convert words which is a string array into int type. i kno string can be converted into int using interger.parseint. but wat abt string arrays??? plz help me out with the above code.

    i did tht its still giving the same errorFor Heaven's sake, what about taking a second to try to understand the code you're copying first? If you really can't fix the error yourself, you have a more serious problem than just convertingStrings to ints.
    And if you want { "1", "2", "3" } to be 123:
    StringBuffer b = new StringBuffer();
    for (int i = 0; i < array.length; i++) {
      b.append(array);
    int result = Integer.parseIn(b.toString());

  • How to retrieve string array using Session?

    Hi, I am having some problem retrieving string arrays through session.
    String personalData[] = new String[17];
    personalData = (String [])session.getValue("PersonalData");
    The coding above isn't working. Advise pls.. Thanks

    The getValue() method is deprecated - you should probably be using getAttribute.
    What about this code isn't working? Looks ok to me, as long as the "PersonalData" object in the session is a String[] it should work.

  • How to get String assigned value

    Hi,
    As String is immutable and we know that the value of string is not changable.
    eg: String abc= new String();
    abc = "INDIA";
    system.out.println("1st abc : "+abc);
    abc=abc.toLowerCase();
    system.out.println("2nd abc : "+abc);
    As we know as string is immutable the value for the 2nd abc gives us india.As 2nd abc creates a new instance object stores in new memory location.
    Then y string is called immutable.It means the value is getting changed.
    Is their a way to retrive my original value or first assigned value for abc i.e INDIA.
    Thanks

    In addiction I have to evaluate every single value because when I found some conditions (like if value=0000 output should be NULL).
    What would be the best way to do it? I'm thinking to develop a custom functoid but I'm not sure it would be the best way, probably it could be done even using XSLT inline transforms, can you point me in the best direction?
    Thank you

    Hi,
    You cannot directly map an array output to any single field in BizTalk mapper.
    Couple of options :
    1) create
    the Xslt or inline C# code
    Refer: 
    http://seroter.wordpress.com/2008/10/07/splitting-delimited-values-in-biztalk-maps/
    2) Shankycheil has
    provided a solution to similar requirement in the below link, u can also refer that.
    https://social.msdn.microsoft.com/Forums/en-US/55ec472d-4f34-4057-b1c6-0e50740f0f6e/how-to-itterate-string-array-values-in-biztalk-mapper?forum=biztalkgeneral
    Rachit
    Thank you, I already seen both posts, but I'm not sure they are what I need or I can't understand well how to use them.
    Speaking about the first solution, as I told before, in the example I should have an array already formed and delimited by a char (something like "obj1attr1-obj1attr2-ob2attr1-obj2attr2". In this situation probably this example could be a good
    point to start from, but how to transform my complex input object in a similar formatted string?
    About the second I don't understand well what is the working solution that they have adopted. Is the 4 steps solution suggested by  Shankycheil? If yes, how can I loop between all array elements and extract all their values?

  • Searching two dimensional string arrays

    Hello, I'm very new to Java. I would like some advice on the code below. What I'm trying to do is: I want the user to enter a 9 digit number which is already stored in an two dimensional array. The array is to be searched and the 9 digit number and corresponding name is to be printed and stored for future reference. Something is wrong with my array checking. If I enter the nine digit number, the program errors and asks me again for the number. If I enter 0-4, I receive an output. I just don't know how to compare string array values. Could someone please help me with this?

  • How can I return Array of String to client

    Hi all,
    I am a new learner about web services, can any one tell me how to return of get a String of array from OMElement ?
    I have two server side method want to create, first method receive an array of string and second method return an an array of String. How should I implement it.
    public org.apache.axiom.om.OMElement OneWayRequest() {
              //How Please help me
    public void LoadDummyNumberForInventory(
         org.apache.axiom.om.OMElement loadDummyNumberForInventory0) {
    //How get the String array ?

  • Newbie trying to sort 2D string array

    Dear all,
    After read some book chapters, web sites including this, I still don't get the point.
    If I have a file like,
    1 aaa 213 0.9
    3 cbb 514 0.1
    2 abc 219 1.3
    9 bbc 417 10.4
    8 dee 887 2.1
    9 bba 111 7.1
    and I load into memory as a String[][]
    here comes the problem, I sort by column 1 (aaa,...,bba) using an adaptation of the Quicksort algorithm for 2D arrays
    * Sort for a 2D String array
    * @param a an String 2D array
    * @param column column to be sort
    public static void sort(String[][] a, int column) throws Exception {
    QuickSort(a, 0, a.length - 1, column);
    /** Sort elements using QuickSort algorithm
    static void QuickSort(String[][] a, int lo0, int hi0, int column) throws Exception {
    int lo = lo0;
    int hi = hi0;
    int mid;
    String mitad;
    if ( hi0 > lo0) {
    /* Arbitrarily establishing partition element as the midpoint of
    * the array.
    mid = ( lo0 + hi0 ) / 2 ;
    mitad = a[mid][column];
    // loop through the array until indices cross
    while( lo <= hi ) {
    /* find the first element that is greater than or equal to
    * the partition element starting from the left Index.
    while( ( lo < hi0 ) && ( a[lo][column].compareTo(mitad)<0))
    ++lo;
    /* find an element that is smaller than or equal to
    * the partition element starting from the right Index.
    while( ( hi > lo0 ) && ( a[hi][column].compareTo(mitad)>0))
    --hi;
    // if the indexes have not crossed, swap
    if( lo <= hi )
    swap(a, lo, hi);
    ++lo;
    --hi;
    /* If the right index has not reached the left side of array
    * must now sort the left partition.
    if( lo0 < hi )
    QuickSort( a, lo0, hi, column );
    /* If the left index has not reached the right side of array
    * must now sort the right partition.
    if( lo < hi0 )
    QuickSort( a, lo, hi0, column );
    * swap 2D String column
    private static void swap(String[][] array, int k1, int k2){
    String[] temp = array[k1];
    array[k1] = array[k2];
    array[k2] = temp;
    ----- end of the code --------
    if I call this from the main module like this
    import MyUtil.*;
    public class kaka
    public static void main(String[] args) throws Exception
    String[][]a = MyUtil.fileToArray("array.txt");
    MyMatrix.printf(a);
    System.out.println("");
    MyMatrix.sort(a,1);
    MyMatrix.printf(a);
    System.out.println("");
    MyMatrix.sort(a,3);
    MyMatrix.printf(a);
    for the first sorting I get
    1 aaa 213 0.9
    2 abc 219 1.3
    9 bba 111 7.1
    9 bbc 417 10.4
    3 cbb 514 0.1
    8 dee 887 2.1
    (lexicographic)
    but for the second one (column 3) I get
    3 cbb 514 0.1
    1 aaa 213 0.9
    2 abc 219 1.3
    9 bbc 417 10.4
    8 dee 887 2.1
    9 bba 111 7.1
    this is not the order I want to apply to this sorting, I would like to create my own one. but or I can't or I don't know how to use a comparator on this case.
    I don't know if I am rediscovering the wheel with my (Sort String[][], but I think that has be an easy way to sort arrays of arrays better than this one.
    I've been trying to understand the Question of the week 106 (http://developer.java.sun.com/developer/qow/archive/106/) that sounds similar, and perfect for my case. But I don't know how to pass my arrays values to the class Fred().
    Any help will be deeply appreciated
    Thanks for your help and your attention
    Pedro

    public class StringArrayComparator implements Comparator {
      int sortColumn = 0;
      public int setSortColumn(c) { sortColumn = c; }
      public int compareTo(Object o1, Object o2) {
        if (o1 == null && o2 == null)
          return 0;
        if (o1 == null)
          return -1;
        if (o2 == null)
          return 1;
        String[] s1 = (String[])o1;
        String[] s2 = (String[])o2;
        // I assume the elements at position sortColumn is
        // not null nor out of bounds.
        return s1[sortColumn].compareTo(s2[sortColumn]);
    // Then you can use this to sort the 2D array:
    Comparator comparator = new StringArrayComparator();
    comparator.setSortColumn(0); // sort by first column
    String[][] array = ...
    Arrays.sort(array, comparator);I haven't tested the code, so there might be some compiler errors, or an error in the logic.

  • How to convert string containing comma seperated values to an array

    my requirement is i have to first convert an comma seperated string to an array
    after that i have to pass the array values to a for loop
    eg:i have a string str=(456,457,487,465,478)
    These values i have to put in an array.
    i then i have to pass the array values to a for loop

    We understand your ¿homeworks? We are helping you, but it seems like you want us to do it.
    Try it yourself with some of the instructions.
    Anyway if there aren´t homeworks, use dinamyc sql:
    declare
    varray := '(45,65,12,4)';
    begin
    execute immediate 'update table set ss=''uu'' where id in ' || varray;
    end;
