There are several problems with your code:
1) It has a syntax error, it is missing an open paren before the file name.
2) It doesn't compile because CharArrayWriter.writeTo() takes a Writer not an OutputStream.
3) You don't flush and close the File, which causes the character not to be written to the file.
Here is some code that works:

import java.io.*;
class Test{
    static public void main(String[] args)throws Exception{
        CharArrayWriter caw=new CharArrayWriter();
        caw.write(65);
        caw.flush();
        caw.close();
        FileWriter fw = new FileWriter("yasir.txt");
        caw.writeTo(fw);  
        fw.flush();
        fw.close();      
    }
}

Out of curiosity, why are you using the CharArrayWriter? You could write to the FileWriter directly without the intermediate buffer.
