Help on classes and methods
I have a date class with a method which is suppose to return the date value a user type in. But no matter what the input is, it keeps returning 0/0/0. really don't know what to do.
Please help frustration is setting up quickly.
import java.util.*;
import static java.lang.System.in;
import static java.lang.System.out;
public class Date1 {
protected int day;
protected int month;
protected int year;

if((newMonth <= 0) || (newMonth > 12)){
throw new DateOutOfBoundsException(" Month must be in the range 1 to 12");
}else{
int month = newMonth;};
int day = newDay;
if (newYear < MINYEAR){
throw new DateOutOfBoundsException(" Year : " + newYear + " is too early");
}else{
int year = newYear;};
public int monthIs(){
return month;
public int dayIs(){
return day;
public int yearIs(){
return year;
public String toString(){
return(month + "/" + day + "/" + year);
public class DateOutOfBoundsException extends Exception {
public DateOutOfBoundsException(){
super();
public DateOutOfBoundsException(String message){
super(message);
public static void main(String[] args)throws DateOutOfBoundsException{
Scanner myScanner = new Scanner(in);

int M, D, Y;
out.print("Please Enter a month to check for its validity: ");
M = myScanner.nextInt();
out.print("Please Enter a day to check for its validity: ");
D = myScanner.nextInt();
out.print("Please Enter a year to check for its validity: ");
Y = myScanner.nextInt();
theDate = new Date1(M, D, Y);
out.println(theDate);

You can't just print the date object. I think what you meant to do was:
out.println(theDate.toString());
Nonsense. When you pass this object to out, its toString method will be invoked.
The problem is in the constructor:
int month = newMonth;This assigns newMonth to a local variable. To assign to a field, write:
this.month = newMonth;or just
month = newMonth;

Pls help me on finding info abt classes and methods....
hi.. I'm new to java .. but i know the very basics of it.. so that i could write a couple of simple programs.. I've been working wit .NET all these days and MSDN library helps me a gr8 deal.. it gives explanation for every class and methods of the class, even explaining the parameters passed into the methods.. I'm currently workin wit J2ME for developing MIDlets... As i know the basics programming isnt very bad.. but where can i find the explanation for the classes used in micro edition or the methods that belong to the classes...
Is there any facility like MSDN library for java where i can find the whole information...?????
Pls help with....

Please help with correcting calling class and method errors
Hi All,
I have created a game (like battleship) for 2 tanks. I can't seem to connect the classes and methods to get the values for the last die face rolled; last direction rolled on a 4 headed dice; the x and y position for each tank; the armour value and the firePower (or hit value) to print.
Each row of these values is supposed to print 50 times using a while loop.
(N.B. The code is appended below my name.)
Could anyone please help me? I would be most grateful. Thank you.

I unzipped the JAR and loaded the classes individually - so now the "reference" issue went away. Instead I now have a new problem, but I will post that seperately. -
Can I use classes and methods for a maintenance view events?
Hello experts,
Instead of perform/form, can I instead use classes and methods, etc for a given maintenance view event, lets say for example I want to use event '01' which is before saving records in the database. Help would be greatly appreciated. Thanks a lot guys!Hi viraylab,
1. The architecture provided by maintenance view
for using EVENTS and our own code inside it -
It is provided using FORM/PERFORM
concept only.
2. At this stage,we cannot use classes.
3. However, inside the FORM routine,
we can write what ever we want.
We can aswell use any abap code, including
classes and methods.
(But this classes and methods won't have any
effect on the EVENT provided by maintenance view)

Classes and methods in BW 7.0
hI ,
I wrote some peice of code in rule and activated in development system .
It was activated and transproted into Test environment .
It went with errors .
The error is :
BI 7.0 is totallly OOABAP with classes and methods .
for each and every rule BI 7.0 will create Class definetion and class implementation .
I have declared glaobal variables in
CLASS lcl_transform DEFINITION.
PUBLIC SECTION.
and i used those variables in methods
CLASS lcl_transform IMPLEMENTATION.
METHOD compute_ZRELALLOC.
when i tranasprorth this rule , the golabl declaration in Class are not going .
Thatswhy my transport failed and it says that syntax error .
how to transport this class ........
Please help meVenkat,
Try look for any SAP Note or create Customer Message to SAP. It's clearly Program Error. We can't collect "lcl_transform" class into Transport Request Independently as it was local Class not Global Class.
Try transporting Transformations again, if it still gives problem. Contact SAP.
Let us know if you implement any SAP Notes.
all the best.

Could you please send me the material Opps concepts Classes and Methods
Hi Experts,
I am working on Opps concepts.I am new to this concept.
Could you please send me the detailed presentation on Abap oops.
Thanks inadvance,
Regards,
Rekha.Hi this will help u.
OOPs ABAP uses Classes and Interfaces which uses Methods and events.
If you have Java skills it is advantage for you.
There are Local classes as well as Global Classes.
Local classes we can work in SE38 straight away.
But mostly it is better to use the Global classes.
Global Classes or Interfaces are to be created in SE24.
SAP already given some predefined classes and Interfaces.
This OOPS concepts very useful for writing BADI's also.
So first create a class in SE 24.
Define attributes, Methods for that class.
Define parameters for that Method.
You can define event handlers also to handle the messages.
After creation in each method write the code.
Methods are similar to ABAP PERFORM -FORM statements.
After the creation of CLass and methods come to SE38 and create the program.
In the program create a object type ref to that class and with the help of that Object call the methods of that Class and display the data.
Example:
REPORT sapmz_hf_alv_grid .
Type pool for icons - used in the toolbar
TYPE-POOLS: icon.

Automatic Display of NEW Data in ALV Report using Classes and Methods
Hi,
I have developed a ALV Report for displaying data from a set of DB tables using ABAP OO, Classes and Methods. The requirement is to have the report output to be automatically updated with the new entries from the DB table at a regular frequency of tiem may be every two minutes.
Could anyone please tell me how can this be acheived.
Thanks and regards,
Raghavendra Goutham P.Yes its possible.

I'm kind of new to this so please bear with me. I'm writing some JSPs within the portal and can't find the JPDK classes and methods, does anybody know where these are? I'm tring to get the IP address of portal visitors for security reasons. Thanks in advance for the help!
The JPDK was not shipped with older versions of the portal - it was only available via download from OTN.
Oracle9iAS release 1.0.2.2 will be the first release to include the jpdk in the base release. -
Hi Experts,
I am studying ABAP Objects, before that I need to know How to use the exsiting classes and Methods in our program and how to search for particular class and methods?
If it explanied with example well and good.
Thanks

Main Class CL_SALV_TABLE
The main class used to create the simple 2D table is the class CL_SALV_TABLE. Create a reference variable for this class. Create an internal table and fill this internal table with data as show below.
REPORT ZALVOM_DEMO1. data: ispfli type table of spfli. data: gr_table type ref to cl_salv_table. start-of-selection. select * into table ispfli from spfli.
Next we need to create the ALV object for the 2D table. The FACTORY method allows you to create the ALV object in 3 ways. You can create the ALV Grid, as a classical list display, as a full screen grid, and finally embedded into a screen container. For this example, we will be working with the full screen grid. Create the call to the FACTORY method. We are importing the object reference into GR_TABLE and passing the internal table ISPFLI.
cl_salv_table=>factory( importing r_salv_table = gr_table changing t_table = ispfli ).
Next we need to display the grid, for this we use the DISPLAY method . Simply call it.
gr_table->display( ).

Functions CL_SALV_FUNCTIONS
Next, add functions to the application toolbar. For this, use the CL_SALV_FUNCTIONS class. Create the object reference variable and receive the object using the GET_FUNCTIONS method of the GR_TABLE object. Call the method SET_ALL to force the ALV grid to show all standard functions.
report zalvom_demo1. data: ispfli type table of spfli. data: gr_table type ref to cl_salv_table. data: gr_functions type ref to cl_salv_functions. start-of-selection. select * into table ispfli from spfli. cl_salv_table=>factory( importing r_salv_table = gr_table changing t_table = ispfli ). gr_functions = gr_table->get_functions( ). gr_functions->set_all( abap_true ). gr_table->display( ).
The result is now you have the standard buttons on the application toolbar.
Display Settings CL_SALV_DISPLAY_SETTINGS
Next, we can change some display settings using the class CL_SALV_DISPLAY_SETTINGS. Create the object reference variable and receive the object using the GET_DISPLAY_SETTINGS method of the GR_TABLE object. In this example, we are setting the Striped Pattern for the ALV Grid rows, and setting the heading in the title bar.
report zalvom_demo1.

Columns CL_SALV_COLUMNS_TABLE and CL_SALV_COLUMN_TABLE
Next, we can change some of the attributes of a specific column in the ALV grid. In this example we will change the Heading Text of a column as well as the color of a column. Create the object reference variable and receive the object using the GET_COLUMNS method of the GR_TABLE object. This will pass you the object for all columns of the ALV grid. To access just one column, call the method GET_COLUMN from the GR_COLUMNS object. In this example, we are accessing the CITYTO column and the CITYFROM column.

Sorts CL_SALV_SORTS
Next, we can add some sorting to the ALV grid. Create the object reference variable and receive the object using the GET_SORTS method of the GR_TABLE object. Next, add the sort by calling the ADD_SORT method of the GR_SORTS object.

Aggregations CL_SALV_AGGREGATIONS
Since we sorted by CITYTO, we can add an aggregation to subtotal the DISTANCE by CITYTO. Create the object reference variable and receive the object using the GET_AGGREGATIONS method of the GR_TABLE object. Next, add the aggregation by calling the ADD_AGGREGATION method of the GR_SORTS object. We also need to modify the call to ADD_SORT to set the SUBTOTAL = ABAP_TRUE.

Filters CL_SALV_FILTERS
Using the CL_SALV_FILTERS class we can setup some filters for the data in our ALV GRID. Create the object reference variable and receive the object using the GET_FILTERS method of the GR_TABLE object, and then simply called the method ADD_FILTER with the parameters.

Layouts CL_SALV_LAYOUT
If you want to allow the user to manage layouts of the ALV grid, you must use the class CL_SALV_LAYOUT. Create the object reference variable and receive the object using the GET_LAYOUT method of the GR_TABLE object. Then simply call the method SET_KEY with the parameters and set the save restriction using the SET_SAVE_RESTRICTION method.

How to implement classes and methods in badi's ?
how to implement classes and methods in badi's? and where i have to write the code based on the requirement?can anyone explain me briefly?
Hi
Every BADI by default Implements an INTERFACE which already contains some methods with parameters.
So you have to find the relavenet method based on the related paramters (by checking the fields in that paramters) you have to double click on the method and to write the code.
see the doc
DEFINING THE BADI
1) execute Tcode SE18.
2) Specify a definition Name : ZBADI_SPFLI
3) Press create
4) Choose the attribute tab. Specify short desc for badi.. and specify the type :
multiple use.
5) Choose the interface tab
6) Specify interface name: ZIF_EX_BADI_SPFLI and save.
7) Dbl clk on interface name to start class builder . specify a method name (name,
level, desc).
Method level desc
Linese;ection instance methos some desc
8) place the cursor on the method name desc its parameters to define the interface.
Parameter type refe field desc
I_carrid import spfli-carrid some
I_connid import spefi-connid some
9) save , check and activate adapter class proposed by system is
ZCL_IM_IM_LINESEL is genereated.
IMPLEMENTATION OF BADI DEFINITION
1) EXECUTE tcode se18.choose menuitem create from the implementation menubar.
2) Specify aname for implementation ZIM_LINESEL
3) Specify short desc.
4) Choose interface tab. System proposes a name fo the implementation class.
ZCL_IM_IMLINESEL which is already generarted.
5) Specify short desc for method
6) Dbl clk on method to insert code..(check the code in AAA).
7) Save , check and activate the code.

Calling Classes and Methods in Transformation Rules
Hi,
I have transformations from Level 1 to Level 2 ODS where based on the source fields Date of Sale(ZDSALE) I have to derive Period to Date and Year to Date from the class ZBI_UTILITY_METHODS and method ATTRIBUTES_GET. How do i incorporate this in my start and transformation routines. Can someone please give me the code for this and also give some sample codes where classes and methods are called in the transformation rules.
Thanks
Priya.Hi Priya,
I suggest you the way to call method in the class like this:
DATA: o_model TYPE REF TO ZBI_UTILITY_METHODS.
" define v_return variables based on type the method give the value
CREATE OBJECT: o_model.
v_return = o_model->ATTRIBUTES_GET( transfer parameter ).
free o_model.
Hopefully it can help you a lot.

Trying to pass parameters between GUI classes and methods
Hi All.
I have been working on a rather large final year project in college and it is getting close to the deadline. It looks as though I need to "tidy up" my code as it contains too many static methods, variables and other bad programming habits. My package consists of many different GUI's and classes. Up until now I have been calling different GUI's with guiName.NameOfMethod. I have been told this is bad practice so I am trying to fix this. Also instead of passing parameters correctly I have been creating static variables in my main class and using them. So for example if one class needed to pass a variable to the other I would first myGlobalVariable = X; in the first class. And then the second class can use this. This is also bad, right?
So I guess im really just looking for a good example or tutorial on how to pass parameters between classes and methods, GUI if possible. Here is an example of how my GUI classes look:

new anotherGUI();
}This is more or less how I have been going about creating my GUI's. These are used as pop ups. The user enters a value and then it is closed.
To be honest I have been able to pass a variable correctly from one class to a GUI class but I have still having difficulty. For example in my code above I can pass the variable into this class but I cannot pass it into clickOK(). An this is where it is needed.
Can anyone please help?
I hope I have explained my problem well.
Thanks in advance.I dont think that is what I need. An example of what I do in my program is:
I have a main GUI with an array of images. There are a number of other small GUI's that appear for certain functions when the user clicks on an image or does some other function. I am trying to pass a value into the GUI class that is used for the smaller "pop up" GUI. So lets say the user has clicked the image in array[12]. Then a GUI is displayed. I need to pass the integer 12 into this class.
Thanks.
