Java Package Naming Convention

Last Updated : Mar 11, 2024

Java Package Naming Convention

In this article we will show you the solution of java package naming convention, an essential component of Java programming that encourages code organization, maintainability, and reuse is the Java package name convention.

It is possible to group similar classes, interfaces, and various other components into a single entity using packages.

Consistent package naming improves code readability and aids developers in comprehending the function and contents of each package.

Lowercase letters are used in Java package names to provide consistency across platforms.

To prevent conflicts and give each package a special identification, it is advised to base the package name on a reverse domain name. We'll talk about the naming convention for Java packages now.

Step By Step Guide On Java Package Naming Convention :-

 * This is a Java code example demonstrating the package naming convention.
 * The package name used in this example is "talkerscode".
package com.talkerscode;
public class Main {
    public static void main(String[] args) {
        System.out.println("Hello, TalkersCode!");
        BufferedReader reader = new BufferedReader(new InputStreamReader(;
        try {
            System.out.println("Please enter your name:");
            String name = reader.readLine();
            System.out.println("Welcome, " + name + "!");
        } catch (IOException e) {
            System.out.println("An error occurred while reading input.");
  1. As you can see, we have written some Java code to demonstrate the package naming standard.
  2. A package declaration is made first: package com.talkerscode;.
  3. In order to assure uniqueness and prevent naming conflicts, this adheres to the package naming convention in which the package name is based on a reverse domain name.
  4. Next, we add the necessary import statements to bring in the relevant Java API classes.
  5. To make reading user input from the console easier in this instance, we import,, and
  6. Next, a public static void main(String[] args) method is defined for the class Main.
  7. The starting point for the execution of the programme is this approach.
  8. To print Hello, TalkersCode! to the console inside the main method, we use System.out.println("Hello, TalkersCode!");.
  9. The standard output stream is referred to as System.out in this case, and the println method displays the specified message followed by a newline.
  10. We build a BufferedReader object called reader in order to read user input from the terminal.
  11. It encloses an InputStreamReader object that reads data from the standard input stream represented by
  12. To deal with any potential IOException that can occur when reading input, we utilise a try-catch block.
  13. We utilise System.out inside the try block to ask the user to input their name.Please enter your name here: println;.
  14. The BufferedReader's readLine() method reads a line of user-provided text and stores it in the name String variable.
  15. Finally, we print a customised welcome message to the console using System.out.println("Welcome, " + name + "!"); where name is concatenated with the surrounding content.
  16. The catch block is executed if an IOException happens while the input is being read.
  17. An error happened when reading the input, and then we use e.printStackTrace() to print the exception's stack trace.
  18. Debugging is made easier by the stack trace, which provides details about the exception and its occurrence.

Conclusion :-

As a result, we were able to understand the concept of java package naming convention.

We also discovered that the package naming structure demonstrates how to read user input and display messages to the console using standard input/output streams.

Following the package name standard helps to improve the organisation and clarity of the code.

I hope this article on java package naming convention helps you and the steps and method mentioned above are easy to follow and implement.
