    Understanding Classes and Objects
    Before we dive into advanced techniques, let's first understand the basics of classes and objects in Java. A class is a blueprint for creating objects, which are instances of the class. Classes define the properties and behaviors of objects, making them essential for object-oriented programming.
    In Java, classes are defined using the 'class' keyword, followed by the class name and body enclosed in curly braces. Objects are created using the 'new' keyword, which allocates memory for the object and invokes the class constructor to initialize the object.
    Advanced Techniques for Java Classes and Objects
    Inheritance
    One of the key features of object-oriented programming is inheritance, which allows a class to inherit properties and behaviors from another class. In Java, inheritance is implemented using the 'extends' keyword. By extending a class, you can reuse code, promote code reusability, and create a hierarchical relationship between classes.
    For example, consider a 'Vehicle' class that defines common properties such as 'make' and 'model'. You can create subclasses like 'Car' and 'Truck' that inherit these properties from the 'Vehicle' class.
    Polymorphism
    Polymorphism is another powerful concept in Java that allows objects to be treated as instances of their superclass. This enables methods to behave differently based on the object they are invoked on. Polymorphism is achieved through method overriding and method overloading.
    Method overriding involves redefining a method in a subclass with the same signature as the method in the superclass. This allows the subclass to provide its own implementation of the method while retaining the method signature.
    Encapsulation
    Encapsulation is the practice of bundling data and methods that operate on the data within a class, restricting access to the data from outside the class. This helps in achieving data hiding, which prevents the direct manipulation of the class's internal state.
    By using access modifiers like 'private', 'protected', and 'public', you can control the visibility of class members. Encapsulation enhances code maintainability, as changes to the internal implementation of a class do not affect other parts of the program.
    Abstraction
    Abstraction is the process of hiding the implementation details of a class and exposing only the essential features to the outside world. This allows you to focus on what an object does rather than how it does it, simplifying the complexity of the system.
    In Java, abstraction is achieved through abstract classes and interfaces. Abstract classes can have abstract methods that must be implemented by subclasses, while interfaces define a contract for classes to implement specific methods.
