Custom classes, Help!

hi every one,
i really need help with custom classes, i just dont
understand how to work with them. Can someone give me a small
tutorial on how to write them, where to save them, and how to use
them in another file.
thank you very much

  • Need help calling and looping custom classes

    Hi, I am writing a code with custom classes in it and another program that calls upon all of the classes in the first program. I can get the second one (L6) to call upon and execute all of the classes of the first (Foreign). However, I need the second one to loop until quit is selected from the menu on Foreign and I can't seem to figure out how to do it. Here are the codes:
    L6:
    public class lab6
    public static void main(String[] args)
    Foreign camount = new Foreign();
    camount = new Foreign();
    camount.get();
    camount.print();
    camount.intake();
    camount.convert();
    camount.vertprint();
    System.out.println(camount);
    Foreign:
    import java.util.Scanner;
    public class Foreign
    private String country;
    private int choice;
    private float dollars;
    private float conversionValue;
    private float conversionAmount;
    public Foreign()
    country = "null";
    choice = 0;
    dollars = 0;
    conversionValue = 0;
    conversionAmount = 0;
    public void get()
         Scanner Keyboard = new Scanner(System.in);
              System.out.println("Foreign Exchange\n\n");
    System.out.println("1 = U.S. to Canada");
    System.out.println("2 = U.S. to Mexico");
    System.out.println("3 = U.S. to Japan");
    System.out.println("4 = U.S. to Euro");
    System.out.println("0 = Quit");
    System.out.print("\nEnter your choice: ");
    choice = Keyboard.nextInt();
    public void print()
    System.out.print("\nYou chose " + choice);
    public void intake()
         Scanner Keyboard = new Scanner(System.in);
              if (choice >= 1 && choice <= 4)
    switch (choice)
              case 1: System.out.println("\nU.S. to Canada");
                        conversionValue = 1.1225f;
                        country = ("Canadian Dollars");
                        break;
              case 2: System.out.println("\nU.S. to Mexico");
                        conversionValue = 10.9685f;
                        country = ("Mexican Pesos");
    break;
              case 3: System.out.println("\nU.S. to Japan");
                        conversionValue = 118.47f;
                        country = ("Japanese Yen");
    break;
              case 4: System.out.println("\nU.S. to Euro");
                        conversionValue = 0.736377f;
                        country = ("European Union Euros");
    break;
                   System.out.print("\nEnter U.S. dollar amount: ");
              dollars = Keyboard.nextFloat();
    public void convert()
    conversionAmount = conversionValue * dollars;
    public void vertprint()
    System.out.println("\nCountry = " + country);
    System.out.println("Rate = " + conversionValue);
    System.out.println("Dollars = " + dollars);
    System.out.println("Value = " + conversionAmount);
    public String toString()
    String line;
    line = "\n" + country + " " + conversionValue + " " + dollars + " " + conversionAmount;
    return line;
    I appreciate any help anyone can give me. This is driving me crazy. Thanks.

    1. first you need to write method to get choice value from Foreign class.
    simply add this method.
       public class Foreign {
          // ... Add this
          public int getChoice() {
             return choice;
       }2. Then in your main, you can obtain with previos method.
    public static void main(String[] args) {
       Foreign camount = new Foreign();
       // remove this. you alredy create an instance in last statement.
       //camount = new Foreign();
       int choice = 0;
       do {
          camount.get();
          choice = camount.getChoice();
          // your process...
       } while (choice != 0);
    }

  • Help understanding custom class to access local sqlite db

    Hi;
    I'm using FB 4.5.
    I'm following a tutorial out of the Adobe Air 1.5 Cookbook. From Chapter 10 in case you're familiar. But I assume there is a common method without having to have the Cookbook in your possession.
    The example employs a custom class, and button presses for all the processes involved in the example. I'm trying to figure out how I can modify this example for my purposes. Loading the dataprovider is the result of a button click.
    I'm new to Flex and OOP is still not a clear picture in my mind, but I can sort of see how this project works, using getter/setter methods.
    Using this custom class, how can I load existing data upon startup?
    Thanks

  • Use of deployment classpath or shared-libraries to pick-up "custom" classes

    Hi,
    I’m trying to determine an approach to dealing with how classes are found in a deployed ADF application via classpath, etc. I’ve tried to explain the situation below as best I can so it’s clear. If you have any comments/suggestions as to how this could be done, it would be much appreciated
    Current Application structure:
    Consists of an application initially deployed to OC4J 10.1.3.4 using an alesco-wss.ear file
    Application contains a single Web Module, initially deployed as wss.war file within the alesco-wss.ear file above.
    The Web Module (wss) was built in JDeveloper 10.1.3.4 using 2 projects, a Model and ViewController project, and uses ADFBC.
    The Model project seems to also generate an alesco-model.jar file in the /WEB-INF/lib/ folder, even though Model classes are in the /WEB-INF/classes/ folder below?
    Exploded structure of application on application server looks something like:
    applications/alesco-wss/META-INF/
    /application.xml <- specifies settings for the Application such as Web Module settings
    /wss/
    /app/ <- directory containing application .jspx pages protected by security
    /images/ <- directory containing application images
    /infrastructure/ <- directory containing .jspx files for login, logout and error reduced security
    /skins/ <- directory containing Skin image, CSS and other files
    /WEB-INF/
    /classes/ <- directory containing application runtime class files as per package sub-directories
    /lib/ <- JAR files used by application (could move some to shared-libaries?) – seems to contain alesco-model.jar
    /regions/ <- directory containing .jspx pages used for Regions within JSPX template page
    /templates/ <- directory containing template .jspx pages used for development (not really required for deployment)
    /adf-faces-config.xml
    /adf-faces-skins.xml
    /faces-config.xml
    /faces-config-backing.xml
    /faces-config-nav.xml
    /region-metadata.xml
    /web.xml
    testpage.jspx <- Publicly accessible page just to test
    The application runs successfully using the above deployment structure.
    We plan to use the exploded deployment structure so that updates to pages, etc. can be applied individually rather than requiring construction and re-deployment of complete .EAR or .JAR files.
    What I’m trying to determine/establish is whether there is a mechanism to cater for a customisation of a class, where such a class would be used instead of the original class, perhaps using a classpath mechanism or shared library?
    For example, say there is a class “talent2.alesco.model.libraries.ModelUtil.class”, this would in the above structure be found under:
    applications/alesco-wss/META-INF/classes/talent2/alesco/model/libraries/ModelUtil.class
    Classes using the above class would import “talent2.alesco.model.libraries.ModelUtil”, so they effectively use that full-reference to the class (talent2.alesco.model.libraries as a path, either expanded or within a JAR).
    From the Oracle Containers for J2EE Developer’s Guide 10.1.3 page 3-17, it lists the following:
    Table 3–1 Configuration Options Affecting Class Visibility
    Classloader Configuration Option
    Configured shared library <code-source> in server.xml
    <import-shared-library> in server.xml
    app-name.root <import-shared-library> in orion-application.xml
    <library> jars/directories in orion-application.xml
    <ejb> JARs in orion-application.xml
    RAR file: all JARs at the root.
    RAR file: <native-library> directory paths.
    Manifest Class-Path of above JARs
    app-name.web.web-mod-name WAR file: Manifest Class-Path
    WAR file: WEB-INF/classes
    WAR file: WEB-INF/lib/ all JARs
    <classpath> jars/directories in orion-web.xml
    Manifest Class-Path of above jars.
    search-local-classes-first attribute in orion-web.xml
    Shared libraries are inherited from the app root.
    We have reasons why we prefer not to use .JAR files for these “non-standard” or “replaced” classes, so prefer an option that doesn’t involve creating a .JAR file.
    Our ideal solution would be to have such classes placed in an alternate directory that is referred to in a classpath such that IF a class exists in that location, it will be used instead of the one in the WEB-INF/classes/ directories, and if not such class is found it would then locate it in the WEB-INF/classes/ directories.
    - Can a classpath be set to look for such classes in a directory?
    - Do the classes have to replicate the original package directory structure within that directory (<dir>/talent2/alesco/model/libraries)?
    - If the class were put in such a directory, without replicating the original package directory structure, I assume the referencing “import” statements would not locate it correctly.
    - Is the classpath mechanism “clever” enough to search the package directory structure to locate the class (i.e. just points to <dir>)?
    - Or would the classpath mechanism require each individual path replicating the package structure to be added (i.e. <dir>/talent2/alesco/model/libraries/ and any other such package path)?
    If we are “forced” to resort to the use of JAR files, does a JAR file used for the purpose of overwrite/extending a sub-set of classes in the original location need to contain ALL related package classes? Or does it effectively “superset” classes it finds in all JAR files, etc. in the whole classpath? That is, it finds talent2.alesco.model.libraries.ModelUtil in the custom.jar file and happily goes on to get the remainder of talent2.alesco.model.libraries classes in the other core JAR/location. Or does it need all of them to be in the first JAR file for that package?
    Any help would be appreciated to understand how these various class visibility mechanisms could be used to achieve what is required would be appreciated.
    Gene

    So, nobody's had any experience with deploying an ADF application, and providing a means for a client to place custom classes in such a way as they're used in preference to the standard application class, effectively to implement a customised class without overwriting the original "standard" class?

  • Custom Search help in Record Working Time

    Hi,
    We have a requirement to add a custom field on RECORD Working Time ( ESS). This field has been added and custom search help is assigned to the data element of the field. The values in the F4 help should vary based on employees department.
    The related code for this requirement is written in the serach help exit. The F4 help is working as expected from backend ( ECC) but not in Portal (ESS).
    I have added the custom field in TCATS_SHLP_ITS. After maintaining this table all the values in F4 help are displaying , whereas it should only display the values under employees department in Record Working time.
    I understand the class cl_xss_cat_value_help_general is responsible for the search help in ESS is there any user exit or enhancement available for this class in order to control the serach values on ESS.
    Thanks in advance.
    regards,
    Pradeep

    note that search help of CAT2 and record working time are different!
    these are teh steps
    please modify the following in the table TCATS_SHLP_ITS as follows:
              1. Execute the T-Code SM31
              2. Enter the table name TCATS_SHLP_ITS.
    or check the class
    CL_XSS_CAT_VALUE_HELP_GENERAL
    or check
    CL_XSS_CAT_VALUE_HELP*
    take an example from Sap note 914125

    Thanks for help.

    If you are talking SE54 and Maintenance Views, when I do an SM30 on the Maintenance View and do SYSTEM->STATUS, I see GUI STATUS ZULG on program SAPLSVIM.  If you look at that status, I see two buttons with dynamic text.  The first one is call GPRF and has dynamic text VIM_PR_STAT_TXT_CH.  You can find a suitable PBO event to set the text of that function code and if that works, find a suitable PAI event to respond to that function.
    I recall finding some documentation on customizing the GUI STATUS but no luck today trying to find it.
    Let us know how it goes.

  • Build app with ODT and Oracle UDT - Error while creating custom class

    Yes I confirm that I choose File->New Website.
    I don't see the following option
    File -> New Project, and then under Visual C#, select ASP.NET Web Application

  • Runtime error while trying to execute custom F4 help in OOP ALV grid.

    Dear All,
    I am trying to add custom search help for one of my column in ALV grid. I'm using OOP ALV, when i click for search help for that column, the system shows runtime error like below.
    I am new to OOP concept and tried to follow program BCALV_EDIT_03. But not getting this error occur. Please help me.
    With regards.

    Hi,
    In order to be able to provide a search help for a field in an ALV you must do the following things.
    1) The field where F4 help need to be attached needs to be made editable.
    2) Create an event handler class to handle the ONF4 event. You can refer the following code:
        CLASS lcl_alv1_handler DEFINITION.
        PUBLIC SECTION.
           "Tohandle F4 helps
           METHODS handle_f4 FOR EVENT onf4 OF cl_gui_alv_grid
                   IMPORTING e_fieldname e_fieldvalue es_row_no er_event_data
                             et_bad_cells e_display.
        ENDCLASS.
       CLASS lcl_alv1_handler IMPLEMENTATION.
          METHOD handle_f4.
    CASE e_fieldname.
         WHEN 'LIFNR'.               "Set F4 for courier vendor
             SELECT lifnr name1 FROM lfa1 INTO TABLE lt_lifnr.
           IF lt_lifnr IS NOT INITIAL.
             CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
               EXPORTING
                 retfield           = 'LIFNR'
                 window_title   = 'Vendors'
                 value_org       = 'S'
               TABLES
                 value_tab       = lt_lifnr
                 return_tab      = lt_return
               EXCEPTIONS
                 parameter_error = 1
                 no_values_found = 2
                 OTHERS          = 3.
             IF sy-subrc = 0.
               READ TABLE gt_final INTO wa_final_t INDEX es_row_no-row_id.
               IF sy-subrc = 0.
                 READ TABLE lt_return INTO wa_return INDEX 1.
                 IF sy-subrc = 0.
                   CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
                     EXPORTING
                       input  = wa_return-fieldval
                     IMPORTING
                       output = lv_lifnr.
                   wa_final_t-lifnr  = lv_lifnr.
                   MODIFY gt_final FROM wa_final_t INDEX es_row_no-row_id.
                 ENDIF.
               ENDIF.
             ENDIF.
           ENDIF.
          ENDCASE.
             CALL METHOD o_alv->refresh_table_display.
          ENDMETHOD.
       ENDCLASS.
        In the above method, GT_FINAL-LIFNR is being overwritten by the LIFNR you had selected       from F4 help. So we will call the refresh_table_display after it to see the result in the ALV.
    3) After creating the ALV object, add the fields to which the F4 has to be added. For this you
        need to declare an internal table based on  lvc_t_f4. Use the following code. Here O_ALV is    my ALV object.:
       CREATE OBJECT o_container
           EXPORTING
             container_name              = 'CUSTCON'
           EXCEPTIONS
             cntl_error                  = 1
             cntl_system_error           = 2
             create_error                = 3
             lifetime_error              = 4
             lifetime_dynpro_dynpro_link = 5
             OTHERS                      = 6.
         IF sy-subrc <> 0.
    *     MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
    *                WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
         ENDIF.
         CREATE OBJECT o_alv
           EXPORTING
             i_parent          = o_container
           EXCEPTIONS
             error_cntl_create = 1
             error_cntl_init   = 2
             error_cntl_link   = 3
             error_dp_create   = 4
             OTHERS            = 5.
         IF sy-subrc <> 0.
    *     MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
    *                WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
         ENDIF.
       CLEAR : gt_f4, wa_f4.
       wa_f4-fieldname   = 'LIFNR'.
       wa_f4-register    = 'X'.
       wa_f4-getbefore   = space.
       wa_f4-chngeafter  = space.
       APPEND wa_f4 TO gt_f4.
       Here I am assigning F4 to LIFNR field in the final internal table that is displayed using ALV.
       After this register this field for F4.
        CALL METHOD o_alv->register_f4_for_fields
           EXPORTING
              it_f4 = gt_f4.
       CREATE OBJECT o_alv_handler.
       SET HANDLER : o_alv_handler->handle_f4 FOR o_alv1.
       The object o_alv_handler is created based on the event handler class.
    I hope that this will solve your issue. Revert if this is solved.

  • Reproducing Incident Form Elements in a Custom Class

    Hello again everyone,
    I am trying to rollout a completely separate module in SCSM to record MACD (Move/Add/Change/Delete) requests. I decided to use the OOB incident module as my base class as it already contained many fields I require (I inherited the properties
    and relationships) and created a new form assembly in Visual Studio to wire the properties to.
    After created the form and labels, I imported the .dll into the Authoring Tool so I can just drag out each property from the MP explorer onto the form. Everything works except for the last few fields which are a bit more complex than a standard list or textbox.
    I cannot seem to add the controls for the more complicated items like "Affected Services" or "Affected Items", when I try to drag them out to the form I get an error saying cardinality is not set to 1... I am guessing this is because
    its trying to map a relationship between a workitem and a service instead of my custom class and a service...
    So I went back into Visual Studio and added a ListView to the form, thinking I will have to wire the data bindings inside the form itself. However, I am stuck as I am not sure where "Services" are being written to, as I will need this location
    to reference in my empty ListView. I have provided my code and commented where I believe I am missing logic. Thank you in advance for any help!
    Note: "servicerelatestoworkitem" is not actually an object, my logic is conceptual and I still have not found which class/object the list of services is being written to.
    C# Code containing button logic (an add button to add a service to the ListView, and a delete button to remove a service from the ListView.
    private void add_services_button_Click(object sender, RoutedEventArgs e)
       // Open list of Services here, allow user to pick a service, then add selected service to "servicerelatestoworkitem"
       // AffectedServicesListView is populated from servicerelatestoworkitem
    private void del_services_button_Click(object sender, RoutedEventArgs e)
        // Test to see if item is being selected and display selected item to confirm ability to manipulate variable
        try
            var itemSelected = ListView.GetIsSelected(AffectedServicesListView);
            MessageBox.Show(itemSelected.ToString());
        catch (Exception ex)
            MessageBox.Show(ex.Message);
        // Remove selected item from servicerelatestoworkitem and refresh AffectedServicesListView
    XAML Code containing the list view and two buttons: (Note: The binding is most likely incorrect, I was just experimenting with it)
    <ListView x:Name="AffectedServicesListView" HorizontalAlignment="Left" Height="95" Margin="10,414.6,0,0" VerticalAlignment="Top" Width="521" ItemsSource="{Binding Path=AffectedServicesListView, Mode=Default, UpdateSourceTrigger=PropertyChanged}">

    Cardinality is a property of relationships classes, not a property of specific relationships. each type of relationship has it's own cardinality values, but the engine only really recognizes "one" and "many". it makes sense to say that
    the "affected user" relationship is many to one, because Each work item can have one and only one affected user, but each users may be the affected user of many work items. The Related work items relationship is a many to many, because each workitem
    may be related to many other work items. it doesn't make sense to say this specific relationship between this IR and that user is "many to one", because each instance is only between one specific object and another specific objects. the cardinality
    just controls how many of those specific relationships instances can exist for each type of relationship. 
    There are no out of the box controls for many to many relationships. the Instance Picker control is designed to support one to one and many to one relationships. you'd have to write your own controls for support many to one relationships. Consider Travis
    Wright's SR Example for 2010, since most of this code should execute in 2012 and 2012r2 with only minor modifications. 
    You'd have to either find the control that defines it, like with the history tab, or recreate it using the
    authoring tool or
    Visual Studio.

    However, the segment Java applet calls a CRM class which has related code and methods.
    Class:  CL_CRM_MKTTG_SEGAP_COM
    Package: CRM_MKTTG_SEG_APPLET.
    Please explain the problem in detail.

  • Access Account assignment data inside custom search help

    Hi Experts,
    I have faced with a challenge and I am stuck. Need some expert advise.  I am developing a custom search help for GL account. Inside the search help exit I have to know what is the account assignment category of the accounting line i am currently accessing in WEB UI. for example i have one item in SC and there is a cost distribution between cost center and WBS element. Now i want to access GL account search help from second line in the account assignment ( ie from line having WBS as Acc Assignment).
    one approach that i can think of is Enhance Accounting WD component and capture the details in a static attribute of a custom class and access them inside the search help exit. I know this will work. But i am looking for more clean approach.
    I saw below code in WD comp method GET_BO_INFO of component controller.
    lo_task_container = /sapsrm/cl_ch_wd_taskcont_fact=>get_task_container_instance( ).
       CHECK lo_task_container IS BOUND.
    * Get the BO type
       ev_bo_type = lo_task_container->get_bo_type( ).
    * Get the BO mapper, BO GUID, and item GUID of the lead selection
       CASE ev_bo_type.
         WHEN /sapsrm/if_pdo_obj_types_c=>gc_pdo_shop.
           lo_bom_sc ?= lo_task_container->get_bom_sc( ).
           ev_hdr_guid = lo_bom_sc->/sapsrm/if_cll_bo_mapper~get_bo_guid( ).
           ev_item_guid = lo_bom_sc->/sapsrm/if_cll_bo_mapper~items_get_lead_selection( ).
    I am not sure if this works. But even if this works I can not get the exact accounting line that the user is currently processing. Any ideas????
    thanks

  • How to register mouselistener for custom class?

    i m trying to create a custom class (extending java.awt.Rectangle)which responds to mouse gestures.
    i m using it as an object on my drawpad which responds to mouse behavior
    like rollover.
    the rollover color change is achieved using canvas' graphics object triggerd by my cutom class
    i m not able to register a mouseevent for the custom class.
    can someone help me in achieving this?
    thanks in advance
    z_idane

    Something like this? Don't think I'd be likely to extend Rectangle, myself, but anyway...
    public class HotSpot extends Rectangle implements MouseMotionListener
        private boolean hover = false;
        // add constructors to taste
        public void mouseMoved(MouseEvent e)
            if (this.hover != (contains(e.getX(), e.getY())
                this.hover = ! this.hover;
                if (this.hover)
                    // "mouse enter" code here
                else
                    // "mouse exit" code here
        public void mouseDragged(MouseEvent e)
    }Obviously you'd need something like this elsewhere,
    myDrawingPad.addMouseMotionListener(new HotSpot(...));

  • Adding info blocks in a custom class for Factsheet

    Hi Experts,
    I need to create a custom class by copying the standard class 'CL_CRM_CCKPT_PROCESS_OPEN'  which should accept input as Activity Types. At present this class only accepts Number of months as Input. This added input field should accept individual multiple values & Ranges and F4 help also needs to be attached for the field.
    I would like to know how to add this new input field to the class 'CL_CRM_CCKPT_PROCESS_OPEN' .
    Any valuable help would be appreciated & points would be rewarded generously for the same.
    Regards,
    Sangeeta.

    Hi,
    You can copy and include your fields in the class using transaction SE24.
    According to your subject  line you are trying to modify an existing factsheet display you own data. I would suggest instead of creating a modifying an existing class, implement your own function module and call this function module directly from the smartform used to for factsheet. This is an easier way to implement modification of factsheets instead of using the classes and displaying the data.
    Reward with points if this helps.

    This appears to be beacuse the class uk/co/agena/minerva/model/Model is a custom class which is based on the software I am using. Does anyone know how I can get around this issue. I have tried incluijng those class files for the custom classes within the jar file, but I continue to get the same issue?
    Any help would be gratefully received.
    Thanks
    Angie

    This error is no longer coming up, it is now saying that it has an unsupported class version error. I believe this may be because the class file and library files have been complied under different versions, is there a method to check this?
