Since you are already using Java 7, why not use the try-with-resources construct to avoid having to do things like close streams:

try( File   file = new File("krasiWrite.txt"); 
     Writer writer = new BufferedWriter(new java.io.FileWriter(file)); )
{ 
     String text = getArrList().toString();
     writer.write(text);
     writer.flush(); // this lines takes whatever is stored in the BufferedWriter's internal buffer
                     // and writes it to the stream
}
catch(IOException ioe) {
   // ... handle exception
}

// now all resources are closed.
