How to Write Java Code without IDE

To write Java code you can use any source code editor like Notepad++, Sublime Text, Atom, etc. Let us create one simple Java program which will print “Welcome to thecoderworld YouTube Channel!“.

Here we are going to use Notepad++ to create the Java program. Here is the snapshot:

public class HelloYouTube {

     public static void main( String []args ) {

	System.out.println("Welcome to thecoderworld YouTube Channel!");


Note:- Your file name and your class name must be same. For example, I create a “HelloYouTube” class, to save this code I have to name my file as and save the file.

So this way you can create your Java program with the help of Notepad++.
