NewPetCollector Game ( Updated ) 

Player Image:

ImageIcon playerIcon = new ImageIcon("/home/sagar_xbitlabs/NetBeansProjects/java_projects/images/mario.png");

Image playerImage = playerIcon.getImage();

g.drawImage(playerImage, pets.get(0).x * 40, pets.get(0).y * 40, 40, 40, null);

Instead of drawing a simple blue rectangle for the player, this code loads an image of Mario ("/home/sagar_xbitlabs/NetBeansProjects/java_projects/images/mario.png") and draws it on the screen. The ImageIcon class is used to represent the image.

Images Location:

In this code, the paths to the player and pet images are specified using absolute paths:

"/home/sagar_xbitlabs/NetBeansProjects/java_projects/images/mario.png"

It's generally a better practice to use relative paths within the project or load images from the classpath.

Apart from these differences, the core logic remains the same: player and pet movement, collision detection, energy management, and game over conditions are handled similarly to the previous example. The use of images for player representation is the main distinction.
