On creating a Java program

0

I am completely new to Java, and I want to start by saying that I am a beginner. I use Macbook.

With that said, I'm going to create, compile and execute a Java program. Don't know if you use the JDK or a text editor called TextPad in Windows, I have Visual Studio Code.

This is what it says in the file with the instructions:

Open the text editor TextPad (Start - TextPad 8, with the letter T). Create a class called Demo. Type the following:
// Demo.java
class Demo {
}
.
Save the text in a file called Demo.java. Create a directory on a suitable drive (for example, the C drive) and save the file there. The directory can be called, for example, programming. On the school's computers, the file is saved on the H drive. Create there a directory called programming and the directory ovens in it.
Add the main method to the Demo class. Expand the program like this:

// Demo.java
class Demo {
public static void main (String[] args) {
}
}
"

Open the text editor TextPad (Start - TextPad 8, with the letter T). Create a class called Demo. Type the following:
// Demo.java
class Demo {
}
.
Save the text in a file called Demo.java. Create a directory on a suitable drive (for example, the C drive) and save the file there. The directory can be called, for example, programming. On the school's computers, the file is saved on the H drive. Create there a directory called programming and the directory ovens in it.
Add the main method to the Demo class. Expand the program like this:

// Demo.java
class Demo {
public static void main (String[] args) {
}
}
"

So this is how I first started oon my macbook: https://i.stack.imgur.com/pwf63.png

The error message I get is:

The declared package "" does not match the expected package "Programmering"

And I was told that I need to write ”Package Programmering;” at the top. I am not sure why that solves the problem, and why it's not mentiooed in the instructions.
