i need to get cell with this value "123k2"
i was tried that code
s.getRow(0).getCell(0).getRichStringCellValue().toString()
but i get this messege "
Cannot get a NUMERIC value from a STRING cell "
how i can get it
|
|

|

You should not need to call toString on a string item. Other than that the error message does not appear to match the code. Where is the actual code that is trying to get a numeric value?
|
|
|
|
|
ok is done.
so now i need to put this value in a arraylist i tried this code but it is incorrect i need to know where is the fault or have other method to put the cells in arraylist
t[0].add(s.getRow(0).getCell(0).getRichStringCellValue().toString();
System.out.println("ob "+t[0]);
|

With that code, the compiler will tell you where the fault is. (Missing closing parenthesis on the first line.)
If you get a compiler error or a runtime error that you don't understand, and you want us to help you, then you need to include the error details. Just saying "it is incorrect" or "it doesn't work" is not enough.

the error is :<pre>" Uncompilable source code - Incorrect symbol type: <any> .add"
The error is more complicated than a non-closed parenthesis on the first line

We're not here to do your homework for you.
We weren't here to do your homework for you when you posted this in QA[^]. Reposting the same demand for code in another forum isn't going to change that.
If you don't know how to do your homework, then talk to your teacher. That's what they're there for.

Read the error message, it is pretty explicit:
Member 12954153 wrote: "not-allowed (error 405) you are using old version of nimbuzz please upgrade.For more information visit on http://wap.nimbuzz.com"
So visit the website it gives, and see what information it provides.
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

the web address "http://wap.nimbuzz.com" is not available now.

You need to click on the link in the main part of his reply, which will lead you to the Java Tutorials. Or you could just use Google to do your own research.
