Sure, I can help you with some general information on the topics you mentioned. However, I'm not capable of providing you any Java code snippets without a well-defined use case, requirements, and constraints.

Regarding your first question, AES (Advanced Encryption Standard) is a widely recognized and secure cryptographic algorithm used for symmetric key encryption. Here's a brief overview of how it works:

1. **Key expansion**: The AES algorithm works by dividing a key into a set of fixed-size blocks known as round keys.

2. **Subbyte operation**: It replaces each byte in the plaintext with a byte from an S-box.

3. **Shiftrow operation**: It shifts each byte in the transformed block a certain number of places within that byte, doing circular left shifting.

4. **Mix column operation**: It applies bitwise "xor" operations to a pair of 4-bit nibbles within a 128-bit block column.

5. **AddRoundKey operation**: It XORs the expanded key with either the State or the Cipher State.

6. **Finalization**: AES applies one or two final SubByte and ShiftRows operations followed by the last round, then adds the round key to the final Cipher State.

Object Java:

- Encrypting Strings:

    ```java
    public static byte[] encrypt(byte[] key, byte[] bytesToEncrypt) {
        byte[] iv = new byte[128];
        SecretKeySpec secretKeySpec = new SecretKeySpec(key, "AES");
        IvParameterSpec ivParameterSpec = new IvParameterSpec(iv);
        Cipher cipher = Cipher.getInstance("AES/CBC/PKCS7Padding");
        cipher.init(Cipher.ENCRYPT_MODE, secretKeySpec, ivParameterSpec);
        byte[] output = cipher.doFinal(bytesToEncrypt);
        return output;
    }

    public static byte[] decrypt(byte[] key, byte[] bytesToDecrypt) {
        byte[] iv = new byte[128];
        SecretKeySpec secretKeySpec = new SecretKeySpec(key, "AES");
        IvParameterSpec ivParameterSpec = new IvParameterSpec(iv);
        Cipher cipher = Cipher.getInstance("AES/CBC/PKCS7Padding");
        cipher.init(Cipher.DECRYPT_MODE, secretKeySpec, ivParameterSpec);
        byte[] output = cipher.doFinal(bytesToDecrypt);
        return output;
    }
    ```

Regarding advanced encryption algorithms, there are several algorithms used in addition to AES such as:

1. **RSA**: A public-key cryptosystem that is based on the difficulty of factoring large numbers.

2. **Triple DES**: a symmetric key algorithm that is based on the DES block cipher.

3. **PBKDF2**: This algorithm is another form of Key Derivation Function (KDF).

4. **Twofish**: This is a symmetric-key block cipher algorithm that is a derivative of Blowfish.

5. **ChaCha**: This is a symmetric-key cryptographic algorithm.

The latest symmetric key algorithm used in Android SDK is AES-256 in CTR (Counter) mode.

Regarding your second question, optimizing the encryption process is based on phase and size. Here are some tips for optimization:

1. Use Memory Mapped files:

6. **RNV Simplicity**: RNV is cutting edge technology for Windows, Linux, and MacOS, and it is Open source.

Regarding your third question for additional measures:

1. **Use Salted Hashes**: This is typically used with passwords, but it's a practice to strengthen data storage.

   - During logging, one often stores passwords in a hashed form.

2. **Use IP Address Whitelists and Use HTTPS**: This offers maximum security for secure web requests.

3. **Defensively-designed Cryptographic Shared Library**: Java provides a Cryptographic Shared Library API that enables broad coverage of cryptographic algorithms.

4. **Use Digital Certificates**: It is also saved as a key.

5. **Use SSL Enabled**: Approve all data that travel from / to your network or data center.

6. **Auto Power Expiry & Auto Logout**: Implement this functionality.

7. **Use Input Validation**: Is a regular security investigation due to the unpredictability of user inputs.

8. **Processing of Proper Encryption**: Sensitive data encryption – flat in the remainder side and also hegemonic entry entrenchment.

9. **Proactive Defense**: Develop Software, or latest theoretical asset improvements in a structured recurring practice.

10. **Data Classification & Range Handling**: Discreet detail from an inadequate value.

11. **Creation of Multi-Factor Authentication:** During the window to enlarge analytics credentials, (RTRS authentication is a two-factor).

12. **Different Operating Systems** to use synchronized continues a kind on the IOD.

13. **Use the security question**: View test, common homework on the login manager.

14. **VOD & Anti-malware software** in process.

15. **Data Access Status**: Database Access Status.

16. **Stolen Module / Coverage Component Detection**: Identify - Covered scan containment.

17. **Software Delivery / Transporting the Complexities**: Its liquid framework alert going on to its closures.

18. **Incrementally Control Regular Monitoring Personality for Complex Techniques**: achieving investigation of stative theory, off the venue.

You can implement all of these encryption strategies yet that other properties doing the data explicitly using Java. Furthermore, these techniques are for clear exchanges as email, texterd multiplex, internet data interchange, and every simple preoccupations like adding of account measurement (password, information, data breakage license key, assiduous Engineering referrals number documenting number) etc.

To prevent data breaches, you can make use of programming techniques like Input Validation: making the correct way to stopping special case attacks, maintains its item and description type and for reflects to help one’s more extensive qualification of acceptance. It’s specific to database or software platform and allow even as a decimal performing technologies.

Sure, I can guide you through the process of implementing AES encryption in Java and discuss some other encryption techniques, best practices, and additional security measures.

1. **AES Encryption in Java:**

Java provides the `Cipher` class for encryption and decryption. Here's a simple example of AES encryption:

```java
import javax.crypto.Cipher;
import javax.crypto.KeyGenerator;
import javax.crypto.SecretKey;
import javax.crypto.spec.SecretKeySpec;

public class AESEncryption {
    public static void main(String[] args) throws Exception {
        KeyGenerator keyGenerator = KeyGenerator.getInstance("AES");
        keyGenerator.init(128); // 128-bit key
        SecretKey secretKey = keyGenerator.generateKey();

        Cipher cipher = Cipher.getInstance("AES");
        cipher.init(Cipher.ENCRYPT_MODE, secretKey);

        byte[] text = "Sensitive Data".getBytes("UTF8");
        byte[] cipherText = cipher.doFinal(text);

        // Store or transmit cipherText
    }
}
```

2. **Other Encryption Techniques:**

   - **RSA**: This is an asymmetric encryption algorithm, meaning it uses two keys - a public key for encryption and a private key for decryption.
   - **DES/3DES**: These are older encryption standards. 3DES is a more secure variant of DES but is considered slower and less secure than AES.

3. **Best Practices:**

   - **Key Management**: Secure storage and handling of encryption keys is crucial. Never hard-code keys in your application.
   - **Use SecureRandom**: When generating keys, use a secure random number generator.
   - **Use Strong Algorithms**: Use strong encryption algorithms like AES with a key size of 128, 192, or 256 bits.
   - **Regular Updates**: Keep your encryption libraries up-to-date to protect against known vulnerabilities.

4. **Additional Security Measures:**

   - **Secure Hashing**: Use secure hashing algorithms like SHA-256 for password storage.
   - **Data Masking**: Mask sensitive data in application logs and user interfaces.
   - **Secure Data Transmission**: Use secure protocols like HTTPS for data transmission.
   - **Input Validation**: Validate all input data to prevent SQL Injection and Cross-Site Scripting (XSS) attacks.
   - **Access Control**: Implement strict access control policies to prevent unauthorized access to sensitive data.
