Processing

To write “Hello World!” in the Processing programming language, you can follow these steps:

1. Open a new text file and save it with the .pde extension (Processing Desktop Edition files). You can also use an external code editor like Visual Studio Code for this purpose if preferred.

2. Type the following code:

   void setup() {
     size(600, 400); // Set window dimensions to 600x400 pixels
   }
   
   void draw() {
     background(255); // Set the background color to white
     textSize(32); // Set font size to 32 pixels
     fill(0); // Set the text color to black
     text("Hello World!", width/2 - 100, height/2 + 75); // Display "Hello World!" centered on the screen
   }
   

3. Save and run your code by pressing F5 (Windows) or Control+R (macOS). You should see the message “Hello World!” displayed in the center of a white window.

Remember, this code can be executed within Processing Desktop Editor as well as from a dedicated sketch in an online IDE like p5js web editor at https://editor.p5js.org/.
