What is Java Cryptography Extension (JCE)?
The Java Cryptography Extension (JCE) is a set of packages that provide a framework and implementations for encryption, key generation, and key agreement, and Message Authentication Code (MAC) algorithms. It provides additional security features and algorithms that have been applied to the Java platform, such as Data Encryption Standard (DES), Triple DES, Blowfish, and Advanced Encryption Standard (AES). In addition, the JCE provides a secure random number generator and message digest classes for computing hashes and message digests. The JCE is an optional package for the Java Development Kit (JDK) and is not included with the default installation.

What is the difference between destructor and garbage collector in Java?
A destructor is a method in a program that is used to clean up after a class when it is no longer in use. This usually involves freeing up memory, deleting resources, and performing other necessary clean-up operations. A garbage collector is an automated process that reclaims memory allocated to objects that are no longer used in a program. Unlike destructors, garbage collectors are not tied to a particular class, but rather are handled by the JVM (Java Virtual Machine). Garbage collectors are used to manage memory in programs by identifying and removing as much as possible unused objects in order to free up space in the computer's memory.

How to pass and return objects in Java?
Passing and returning objects in Java works the same way as passing and returning other values. When a method needs an object as an argument, the object reference can be passed as the argument — the same as primitives. When a method needs to return an object reference, it can just return the reference to the desired object. For example, if you have a class called Employee and you want to pass and return an Employee object in a method, you can do it like this: // Pass an employee object to a method public void setEmployee(Employee emp){ // do something with the employee } // Return an Employee object from a method public Employee getEmployee(){ // create a new Employee object Employee emp = new Employee(); // return the object return emp; }

No, not all Java objects need to be persisted. Only objects that have to be stored in a persistent storage system (like a database) need to be persisted. However, most Java objects can and should be stored in an effective data structure that is suitable for their purpose.

How to use a vocoder as an instrument?
1. Choose an audio source to use as your "modulator," such as a vocal take or a synthesizer playing a simple melody. 2. Insert the audio source into an on-board vocoder or insert a third-party plugin vocoder into your DAW. 3. Set the vocoder's playback parameters. 4. Set the vocoder's "carrier" source. This is typically an oscillator of a synthesizer. 5. Adjust the filter frequency and Q knob, as well as other parameters as desired, to shape the sounds created. 6. Add modulation to add movement and interest to the sound. Common modulation sources include LFOs, envelopes, and MIDI controllers. 7. Route the vocoder’s output to a mixer track and record it or directly to your master buss. 8. Use creativity and experimentation to explore vocoder sounds.
