Packages

In Java, a package is a namespace used to organize classes and interfaces. Packages help avoid name conflicts and make it easier to locate and use classes and interfaces.

Types of Packages:

  1. Built-in Packages: These are provided by Java. Examples include:

    • java.util
    • java.io
    • java.math

  2. User-defined Packages: These are created by developers to organize their own classes.

Example of Creating and Using Packages:

Creating a package:

package com.example.animals;

class Dog {
    void bark() {
        System.out.println("Barking...");
    }
}

Using a class from a package:

import com.example.animals.Dog;

public class Main {
    public static void main(String[] args) {
        Dog dog = new Dog();
        dog.bark();  // Output: Barking...
    }
}
