The following example demonstrates How to Import a Package in Java.

Step 1: Create a Package

First, let’s create a simple package and a class inside it. Create a directory structure as follows.

    └── (inside the mypackage directory):

package mypackage;

public class MyPackageClass {
    public void displayMessage() {
        System.out.println("This is a message from MyPackageClass.");

Step 2: Create a Java Program That Imports the Package

Now, let’s create a Java program that imports the mypackage package and uses the MyPackageClass from that package: (outside the mypackage directory):

import mypackage.MyPackageClass; // Importing the MyPackageClass from mypackage

public class ImportDemo {
    public static void main(String[] args) {
        // Create an object of MyPackageClass
        MyPackageClass myObject = new MyPackageClass();

        // Use a method from MyPackageClass

Step 3: Compile and Run

Compile both and Make sure that both files are in separate directories, and the directory containing mypackage is in your classpath.

javac mypackage/

Then, run the ImportDemo class:

java ImportDemo

The program will import the mypackage package and use the MyPackageClass to display a message. This demonstrates how to import and use classes from a package in Java.
