Convert exception stacktrace to String object

Usually whenever a exception occurs, we use the method printStackTrace() on the exception object to display the stacktrace. However, if the stacktrace has to be stored into a String object then the following piece of code will prove handy:

  /**
     * Creates and returns a {@link java.lang.String} from t’s stacktrace 
     * @param t Throwable whose stack trace is required
     * @return String representing the stack trace of the exception
     */
    public String getStackTrace(Throwable t) {
        StringWriter stringWritter = new StringWriter();
        PrintWriter printWritter = new PrintWriter(stringWritter, true);
        t.printStackTrace(printWritter);
        printWritter.flush();
        stringWritter.flush(); 

       return stringWritter.toString();
    }
