How has KeyStore changed in recent Java versions?

        
        // Example of using KeyStore in Java
        import java.security.KeyStore;
        import java.security.cert.Certificate;

        public class KeyStoreExample {
            public static void main(String[] args) throws Exception {
                // Load a KeyStore
                KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());
                keyStore.load(null, null); // using default or null for password

                // Create and set a new KeyStore entry
                String alias = "myKey";
                Certificate cert = ...; // Load or generate your certificate.
                keyStore.setCertificateEntry(alias, cert);

                // Retrieve a Certificate
                Certificate retrievedCert = keyStore.getCertificate(alias);
                System.out.println("Retrieved Certificate: " + retrievedCert);
            }
        }
