Default Create pem encoded csr file ouput

In chapter 6, PKCS10CertificationRequest

the PKCS10CertificationRequest class creates pem encoded csr line output.

To create file output, (rather than display output)

I added a following code in main();

FileOutputStream fOut = new FileOutputStream("pkcs10.req");
fOut.write((request.getEncoded()));
fOut.close();

However, gerenated file "pkcs10.req" seems to be der encoded file rather than pem encoded one.

How can I create pem encoded Certification Request file output?

use following method
public static void pemEncodeToFile(String filename, Object obj, char[] password) throws Exception{
PEMWriter pw = new PEMWriter(new FileWriter(filename));
if (password != null && password.length > 0) {
pw.writeObject(obj, "DESEDE", password, new SecureRandom());
} else {
pw.writeObject(obj);
}
pw.flush();
pw.close();
}


and call like this.

pemEncodeToFile("pkcs10.req", request, null);
