How to Store Private/Public Key in Keystore

I can not simply make sense of this KeySTore Class.

I have private and public key and I simply want to use them in KeyStore to use later.

KeyPairGenerator keyGen = KeyPairGenerator.getInstance("DSA");

SecureRandom random = SecureRandom.getInstance("SHA1PRNG", "SUN"); java.security.NoSuchProviderException

keyGen.initialize(512 , random);

KeyPair keypair = keyGen.genKeyPair();

PrivateKey priKey = keypair.getPrivate();

PublicKey pubKey = keypair.getPublic();

File f = new File("c:\keystore");

// Create an empty keystore object

KeyStore keystore = KeyStore.getInstance(KeyStore.getDefaultType());

?

// code to store private and public key in keystore

// Save the new keystore contents

FileOutputStream out = new FileOutputStream(keystoreFile);

keystore.store(out, password.toCharArray());

out.close();

Can some one please help me with missing code.
