How to write the method?

How do i write the method to generate the following pattern...
++++++++++ 1. method name: drawPattern
-+++++++++ 2. method takes an int as parameter that determines
--++++++++ the pattern width/height
---+++++++ 3. method returns nothing
----++++++
-----+++++
------++++
-------+++
--------++
---------+
So far i got :
private static void drawPattern (int width, int height) {
what else should i include?
Thanks!

what else should i include?how about a method body???
Sorry couldn't resist.
Big hint: Look at for loops (I did it with 3).
I would give you my code but this is a homework problem, so my conciousness prevents me from just giving you the solution.

How to write logout method

hi
how to write logout method..... i am new to programming
protected void logOut(){
asap

When I posted my first reply, I was thinking of writing to an output log. Do you mean "logout" like in web applications???
You don't need to write any special code for that. At the most, you would want to clean up the resources like connections, sockets,... created by the application. If you have some mechanism which retains some "login" information, you might reset it to some default value.
Why don't you be specific with your question instead of writing in such a vague manner?

How to write the start routine in the transformations ?

Hi Experts,
I am working on BI 7, As I want to write a start routine in transformations of 0FIGL_O02 DSO, to allow the GL accounts with cost center data. Already there is a delete statement please find.
*DELETE SOURCE_PACKAGE where BAL_FLAG = 'X'. I had made comment to allow the G/L accounts. since I have some GL Accounts which does'nt have the cost center data, so in this case I have to write a ABAP code to allow this G/L accounts with cost center data.
So Let me know if anyone can help me how to write the ABAP code in the start routine.
Thanks

How to write the expression when create the calculated column?

Dear,
I want to create some calculated column in my attribute view, but I don't know how to write the code in the expression, is there any introduction about this part, how to use those function and how about the grammar in this expression code ? or is there any example about this calculated column?
Thanks for your sincerely answer.

Hi Zongjie,
you can find some information about the creation of calculated columns in the HANA Modeling Guide (http://help.sap.com/hana/SAP_HANA_Modeling_Guide_for_SAP_HANA_Studio_en.pdf).
Within chapter 6.2.1 (Create Analytic Views) you can see under point 7 some basics and also a simple example. The same is also valid for Calculation Views.
Chapter 8.9 (Using Functions in Expressions) describes the different available functions.
You also can use the integrated search in the HANA Studio by clicking the "?" button in the button left corner. Then you get some links in the side panel with related information.
In general you can write your expression manually or you can just drag and drop the functions, elements, operators into the editor window. For example if you drag and drop the "if" function into the editor window you get "if(intarg,arg2,arg3)" inserted. The arguments can be replaced manually or also by drag and drop.
It is also worse to use the "Validate Syntax" button on top of the editor window. It gives you directly a feedback if your expression syntax is correct. If not you get some helpful information about the problem (ok, sometimes it is a little bit confusing because of the cryptic error message format ).
Best Regards,
Florian

How to write the exceptions in function module

dear all,
how to write the exceptions in function modules with example.
thanq
jyothi

Hi,
Raising Exceptions
There are two ABAP statements for raising exceptions. They can only be used in function modules:
RAISE except.
und
MESSAGE.....RAISING except.
The effect of these statements depends on whether the calling program handles the exception or not. The calling program handles an exception If the name of the except exception or OTHERS is specified after the EXCEPTION option of the CALL FUNCTION statement.
If the calling program does not handle the exception
· The RAISEstatement terminates the program and switches to debugging mode.
· The MESSAGE..... RAISING statement displays the specified message. Processing is continued in relation to the message type.
If the calling program handles the exception, both statements return control to the program. No values are transferred. The MESSAGE..... RAISING statement does not display a message. Instead, it fills the system fields sy-msgid, sy-msgty, sy-msgno , and SY-MSGV1 to SY-MSGV4.
Source Code of READ_SPFLI_INTO_TABLE
The entire source code of READ_SPFLI_INTO_TABLE looks like this:
FUNCTION read_spfli_into_table.
""Local Interface:
*" IMPORTING
*" VALUE(ID) LIKE SPFLI-CARRID DEFAULT 'LH '
*" EXPORTING
*" VALUE(ITAB) TYPE SPFLI_TAB
*" EXCEPTIONS
*" NOT_FOUND
SELECT * FROM spfli INTO TABLE itab WHERE carrid = id.
IF sy-subrc NE 0.
MESSAGE e007(at) RAISING not_found.
ENDIF.
ENDFUNCTION.
The function module reads all of the data from the database table SPFLI where the key field CARRID is equal to the import parameter ID and places the entries that it finds into the internal table spfli_tab. If it cannot find any entries, the exception NOT_FOUND is triggered with MESSAGE ... RAISING. Otherwise, the table is passed to the caller as an exporting parameter.
Calling READ_SPFLI_INTO_TABLE
The following program calls the function module READ_SPFLI_INTO_TABLE:
REPORT demo_mod_tech_fb_read_spfli.
PARAMETERS carrier TYPE s_carr_id.
DATA: jtab TYPE spfli_tab,
wa LIKE LINE OF jtab.
CALL FUNCTION 'READ_SPFLI_INTO_TABLE'
EXPORTING
id = carrier
IMPORTING
itab = jtab
EXCEPTIONS
not_found = 1
OTHERS = 2.
CASE sy-subrc.
WHEN 1.
MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno.
WHEN 2.
MESSAGE e702(at).
ENDCASE.
LOOP AT jtab INTO wa.
WRITE: / wa-carrid, wa-connid, wa-cityfrom, wa-cityto.
ENDLOOP.
The actual parameters carrier and jtab have the same data types as their corresponding interface parameters in the function module. The exception NOT_FOUND is handled in the program. It displays the same message that the function module would have displayed had it handled the error.
Or
just have to decide what exceptions u want and under what conditions.
then declarethese exeptions under the exceptions tab.
in the source code of ur function module.
if
like this u can code .
now when u call the function module in tme mainprogram.
if some error occurs and u have declared a exception for this then it will set sy-subrc = value u give inthe call of this fm.
in the fm u can program these sy-subrc values and trigger the code for ur exception.
Please reward if useful
Regards,
Ravi

How to write the dynamic code for RadioGroupByKey and Check Boxes?

Hi,
Experts,
I have created a WD ABAP application in that i have used RadioGroupByKey and CheckBox Ui elements but i want how to write the dynamic code to that i want to display male and female to RadioGroupByKey and 10 lables to check boxs.
Please pass me some idea on it and send any documents on it .
Thanks in advance ,
Shabeer ahmed.

Refer this for check box:
Do check :
bind_checked property is bind to a node with cardinality of 1:1
CHECK_BOX_NODE <---node name
-CHECK_BOX_VALUE <--attribute name of type wdy_boolean
put this code under your WDDOMODIFYVIEW:
DATA:
lr_container TYPE REF TO cl_wd_uielement_container,
lr_checkbox TYPE REF TO cl_wd_checkbox.
get a pointer to the RootUIElementContainer
lr_container ?= view->get_element( 'ROOTUIELEMENTCONTAINER' ).
lr_checkbox = cl_wd_checkbox=>new_checkbox(
text = 'WD_Processor'
bind_checked = 'CHECK_BOX_NODE.CHECK_BOX_VALUE'
view = view ).
cl_wd_matrix_data=>new_matrix_data( element = lr_checkbox ).
lr_container->add_child( lr_checkbox ).

               ResultSetMetaData md = rsexport.getMetaData();
               int columns = md.getColumnCount();
               String fieldNames[]={"No","Name","Author","Date","Id","Issued","Return"};
               //write fields names
               String rec = "";
               for (int i=0; i < fieldNames.length; i++)
