It's rather unpractical to code in Java this way, but in this tutorial I'll show that for simple applications, the whole process is very straightforward. All we need is a Java Development Kit and the favorite text editor.
Let's create a file called MyProject.java
public class MyProject { public static void main(String[] args) { System.out.println("I was made without an IDE!"); } }
Now we have to open terminal (or PowerShell / cmd in Windows) and compile it with the following command:
javac MyProject.java
It will create a new file, MyProject.class. The .java file has been translated by javac to .class file, which is more suitable to be executed by machines. The following command will execute it:
java MyProject.java
And you should see the message written by us in the terminal:
I was made without an IDE!
