This code snippet gets the default keystore used by the Java keytool and displays the list of aliases along with the key type (certificate or private key). 
import java.io.File;
import java.io.FileInputStream;
import java.security.*;
import java.util.Enumeration;

public class GetDefaultKeyStore {
    public static void main(String[] args) throws Exception {
	KeyStore ks = getDefaultKeyStore();
	Enumeration<String> aliases = ks.aliases();
	while(aliases.hasMoreElements()) {
	    String alias = aliases.nextElement();
	    System.out.print(alias);
	    System.out.println(ks.isCertificateEntry(alias) ? ": certificate" : ": private key");
	}
    }

    private static KeyStore getDefaultKeyStore() throws Exception {
	KeyStore ks = KeyStore.getInstance(KeyStore.getDefaultType());
	ks.load(new FileInputStream(
		    new File(System.getProperty("user.home"), ".keystore")
		), 
		null
	);
	return ks;
    }
}


The default keystore used by the above code is: $HOME/.keystore.
