How to store serval char variables into a string variable?

I have serval char variables, but i don't know how to put them together (without using arrays). I am thinking to store these char variables into a string variable but i don't know how to do it. For example,
char letter1 = 'a', letter2 = 'b', letter3 = 'c';
String letters;
then how can i do to make letters = "abc" from using letter1,2,3?
I am just a beginner of Java, if anyone can help me, i will appreciate that very much!!!

String letters=""+leter1+letter2+letter3;is fine and dandy. What it actually compiles to is
String letters = new StringBuffer().append(letter1).append(letter2).append(letter3).toString();Which ofcourse is much more code to write, but still good to know.
So do see the API for java.lang.StringBuffer.

You can't store the sq01 output into internal table.
Once you create the query it will generate the abap program, in that program you can see the contents.

Hi Sridhar,
I would like to Replace the Charecter values with numeric value in my string.
Exp : first in my string I am having the value like this : 'ABCD1234' ( may be any char and num values ), and I want too get it by '99991234'.
So, if i understand you correctly, you want to replace all characters in a string with 9 as in the above example, irrespective of position of the character, if so try with the below code.
DATA: l_str TYPE string.
l_str = 'ASKHSIUDNSBDKJSDH124312431243124saasdfsf'.
REPLACE ALL OCCURRENCES OF REGEX '\D' IN l_str WITH '9'.
IF sy-subrc EQ 0.
WRITE: l_str. "Result will be 9999999999999999912431243124312499999999
ENDIF.

How to store array of data into a single row of table ,using any of Stmts

HI Friends,
Based on my requirements ,i have retrived a set of data from a XXX.jsp page using a request.getParameter() and stored into single dimenssional array . Now i am paassing that array to JAVA class to store a into some table .
In JSP page users can add text boxes dynamically based on his intrest then those attributes will store in table .it means table attributes are not conatant , it table attributes may change at any time when user adds any textboxs or any fields on JSP page ....thats my module ..
Now i wanted to store all array of data into Table in a single row .......thats is my requirements .
How can we use prepareStatement and Statement to store array of results intoo table row ...on each iteration i wanted to store array of results into table atributes ..It means entire array of results should to into table row at time .....coule any one write sytax ,how we do this...
could any one suggest me stps that i can impliment ......?....please reply ASAP

Well ..you code can be works for constant number of attributes in table .oopss here my requirement is table attributes not fixed ,we cant put constant number of place holder(? ) in a statement ,because those are not fixed ,
Let me explain here :
i am doing in that way only. As i mentioned you Table attributes are not constant .It may very if users add any fields dynamically on JSP page .If users have option to add any text box on Jsp page ,then that attribute will store in table as a attribute .
Now i amable fetching the all dyamic form data and stored in a Result Array below ...in this iteration all form result data are from jsp page as suggestion form ,it should stored in table in single row on corrsponding attribtes ......next time when users fills FROM ,then those data i am fetching and storing in a Result Array as below and need to store in corrsponding table attributes in a single row ....
for(int i=0;i<result.length;i++)
               System.out.println(result);
               pst3=connection.prepareStatement("insert into *emprecord* values(?)");
               if(!result[i].equals(""))
                    System.out.println(result[i]);
                         pst3.setString(1,result[i]);
                         pst3.executeUpdate();
Thnks in advance ....let me know the the way we can store dynamic form data into dyanamic table ...

How do I pass single quotes into a string variable?

Thanks for any help?
Example
Select xdat, yday
from foo
where
xdat = to_char(sysdate, 'mm/dd/yyyy')
How do I pass the single quoted stuff above into a string variable?

Thank you but that is not the same thing. I am building a dynamic sql statement and need to pass the quoted material into a statement that is quoted Is that not what my example above shows?
My example above has a quoted string inside a string. I think this is exactly what you were asking for.

How to get a "char variable" with presentation variable???

I want to pass a char variable with presentation variable, I don't have problems if I pass "int".
For example in answers page I add a column that contains years of my dimension. 2000 until 2012 and prompted my presentation variable "year" (from my dashboard prompt) and when I go to dashboard if I choose in my prompt 2006 in my report appear 2006...any problem and easy. But my problem is if I would pass a char variable, in my prompt also I have months but not numbers else names: January, February, March...and a presentation variable that name is "month". If I do the same report but change column year to month (name) I don't have any results and I have an error.
How can I solucionate this???
Thank you!!

Alex,
Do you have separate columns for Year and Month Name. If Yes, Then why it is so confusing?
1. create a dashboard prompt with month name column
2. Assign it to monthname variable
3. In your report use above variable any where.., but what ever you are doing should be logical and valid to get some data.
In general above approach will work.
You said, "No! I don't want to do a filter with month! I would like to pass this variable, in this example don't make sense but I need to pass a char variable with presentation variable to do another things..."
what does that mean, what you are trying to do with the variable in your report. If you give a example that would be better.

How do you store input from keyboard into a string array

I am trying to learn java and one of the programs I am trying to write needs to be able to accept a machine hostname at the keyboard and stuff it into a string array element. I am sure I will be using something along the lines of:
BufferedReader in = new BufferedReader(new InputStreamReader(
                         System.in));
               String str = "";
               System.out.print("Enter a FQDN to look up: ");
               str = in.readLine();
but how do I get the input stuffed into hostname[ ].
Any hints or assistance will be appreciated.
Michael

Well part of. I need to be able to take a random number of hostnames (ie. mblack.mkblack.com, fred.mblack.com, joe.mblack.com, ...) and after the user presses the enter key between each entry, the inputted information is stored in an array element. for example with the three shown above the array would look like this after the user finished.
hostname {"mblack.mblack.com","fred.mblack.com","joe.mblack.com"};
the algorithm would be
Prompt for hostname
get user input and press enter
store hostname into array element
prompt for next hostname or enter with no input to complete entry and execute lookup.class methods.
I have the program written and working fine if I use a static array where I put the hostnames in the list, but cannot figure out how to get the information from the keyboard to the array element.
Thanks for the help though, the response is very much appreciated.
Michael

How to store the webdynpro variable in broser's cookie

Hi,
I have the requirement like that I need to store the customer number in the browser's session such that this customer number is available to other aplications in the portal. other aplications are not only the the webdynpro aplications but also other aplications like crystal reports. I came to know that this can be done by storing the customer in the browser's cookies.
Please reply if any one know how to do this thing.
Thanks in advance.

If i understand you correctly you want to store the values of the local variable whenever you read from it? If you want to do this then simply run a wire from the local variable (in read mode) to the edge of the while loop, right-click on the terminal and select 'enable indexing', and this will create an array of these values at this point.
I hope this helps you..

How to store data from channels into constants

Hi
I currently have a six channel data acquisition system for LVDTs. The way the process works is we do a calibration run on the LVDTs and store the values we get and then use these baseline values during actual measurement. My question is how do I acquire these values and store them in constants within the program itself ? I know we can write these values to an external excel file or text file but can we store them within the program so that I have them available even if I close and open the program again?

Perhaps this will work for you.
