  • How to get the message from a Runnable class

    The Schedule class is actually a JFrame, what I want to do is to "get" the message from Scheduler Class and display it in a JTextField, to let user know what is doing.
    How can I approach this?
    public class Schedule {
        @SuppressWarnings("static-access")

            Scheduler.msg = msg;
        public static String getMsg() {
            return msg;

  • How to get the subclass from a super class( or interface)

    hi,
    I want to get subclass from a super class (or a interface), how to do that? the subclass of a interface means the class implementing the interface.
    for example;
    List ls;
    I want to get the subclass of ls, i.e., LinkedList, Stack, Vector......
    AbstractList al;
    the subclass of al, i.e., ArrayList, Vector.......
    thanks
    Aiwu

    List ls = new ArrayList();Since ls has been declared as a List we can only use List methods
    with it. This is a good thing because we might later want to change
    it to some other sort of List.
    I want to get subclass from a super class (or a interface), how to do
    that?The instance of the subclass declared above did not really come
    from the super class. A class "knows nothing" about its
    subclasses: many sub classes would not even exist at the time
    the class was written.

  • How to get HTTP headers from Data Provider Class?

    Hi,
    I'm the beginner in SAP NetWeaver Gateway. Using Service Builder I created CRUD OData web service and implemented CRUD operations in Data Provider Class. Data Provider Class has methods like MYENTITY_GET_ENTITYSET, MYENTITY_GET_ENTITY, MYENTITY_CREATE_ENTITY, MYENTITY_UPDATE_ENTITY. How can I get HTTP headers from the methods of this Data Provider Class?

    You can do so by using the following code in DPC
    Data :  Lo_facade type ref to /IWBEP/IF_MGW_DP_INT_FACADE.
    lo_facade     ?= /iwbep/if_mgw_conv_srv_runtime~get_dp_facade( ).
    lt_client_headers = lo_facade->get_request_header( ).

    thanks
    You could make your life a little easier and only use 1 format string.  Use "%03b%02b%03b" for the format string.  You can then expand the format string to allow multiple inputs.  You will do the job of 4 functions with just 1.
    "%3b" just says to give 3 spaces for the binary number.  But any preceding 0s will be turned into spaces.  Adding the 0 in there tells the format string to prepend 0s instead of using spaces.
    There are only two ways to tell somebody thanks: Kudos and Marked Solutions

  • How to get specific character from a string

    I have a value such as: 0-5 or 123-30. This is a combination
    from 2 different IDs.
    All I need is to get the number on the right (5 from 0-5 OR
    30 from 123), any number on the right of the "-" character not
    including
    the "-"
    I'm not sure what ColdFusion function can I use safely.
    I said safely since all I can find is either Left or Right
    functions. With these 2 functions, I need to specify the number of
    character to extract while in my case the application is growing so
    the ID may currently be only 1 digit each (0-5) but later it may
    grow longer (123-5677).
    If anyone know the function, please help me. Thank you!

    Something like this?
    Mid(string, Find("-",string)+1 ,
    Len(string)-Find("-",string))
    Since
    Mid(string, start, count)
    and
    Len(string or binary object)
    and
    Find(substring, string [, start ])
    Or perhaps ....
    ListLast(string, "-")
    since
    ListLast(list [, delimiters ])

  • How to get a formula from the user from a text box in a webpage

    Hi. I would like to know how to get the formula from the user who enters in a textbox. This formula can have any number of variables starting with a and goes on.
    The complexity of the formula can go upto sin, cos, ln, exp. Also user enters the minimum and maximum values of these variables. Based on a specific algorithm (which I use) I would calculate a *set of values, say 10, for each of these variables, substitute in the formula and based on the result of this formula, I select ONE suitable  value for each of the variables.
    I don't know how to get this formula (which most likely to be different each time) and substitute the values *which I found earlier.
    Kindly help me out in this issue.
    Thanks

    The textbox is the easy part. It's no different than getting a String parameter out of an HTTP request.
    The hard part is parsing the String into a "formula" for evaluation. You'll have to write a parser or find one.
    Google for "Java math expression parser" and see what you get.
    Or write your own with JavaCC.

    Hi,

    String code = null;

    tf.setText(code);
    I haven't tested this code.

    Your code would change accordingly, depending on the instance.Refer to the product documentation for this.

    getCurrentRow() would always return null if no setCurrentRow() is used.
    Please check the page design and understand how many rows of VO are there. You can also use the following to get the row:
