Examples of java.io.PrintWriter

java.io.PrintWriter
PrintWriter is a class which takes either an OutputStream or Writer and provides convenience methods for printing common data types in a human readable format on the stream. No IOExceptions are thrown by this class. Instead, callers should call checkError() to see if a problem has been encountered in this Writer.

        FileWriter writer = null;
        try {
            File f = new File(getBaseDir() + "/" + TRACE_FILE_NAME);
            f.getParentFile().mkdirs();
            writer = new FileWriter(f, true);
            PrintWriter w = new PrintWriter(writer);
            s = dateFormat.format(new Date()) + ": " + s;
            w.println(s);
            if (e != null) {
                e.printStackTrace(w);
            }
        } catch (IOException e2) {
            e2.printStackTrace();
