What are best practices for working with classes?

// Example of best practices for working with classes in Java

// Encapsulation: Use private fields and public methods
public class Person {
    private String name; // private field

    // Constructor
    public Person(String name) {
        this.name = name;
    }

    // Public getter method
    public String getName() {
        return name;
    }
}

// Inheritance: Extend a base class
public class Employee extends Person {
    private double salary;

    public Employee(String name, double salary) {
        super(name); // Call constructor of the superclass
        this.salary = salary;
    }

    public double getSalary() {
        return salary;
    }
}

// Polymorphism: Overriding methods
public class Manager extends Employee {
    public Manager(String name, double salary) {
        super(name, salary);
    }

    @Override
    public String getName() {
        return "Manager: " + super.getName();
    }
}
