The transition from a class (blueprint) to an object (instance) is the core of Java programming. This project demonstrates the "lifecycle" of a virtual pet. We declare a Cat template, allocate memory using the new keyword, and then manually define its unique characteristics: "Barsik", aged 3. This process, known as object instantiation, creates a concrete entity in the JVM's Heap memory.

• Object Instantiation: Successfully used the new keyword to create a Cat instance.
• State Assignment: Manually assigned "Barsik" and 3 to the object fields.
• Data Verification: Implemented a reporting mechanism to confirm the pet's attributes.
• Architectural Separation: Divided responsibilities into Model, Service, and Reporter layers.
• Naming Conventions: Followed PascalCase for classes and camelCase for variables.

• Java 8+ (Object Instantiation, Field Access)

• Cat: The Model. Stores catName and catAge.
• PetInitializer: The Service. Handles the "birth" and data assignment.
• PetReporter: The View. Displays the pet's status.
• VirtualPetApp: The Orchestrator. Coordinates the creation and verification process.

[SYSTEM]: A new pet has been created!
Pet Name: Barsik, Age: 3
