Step 3: The Block class

Explore how to implement the Block class for a Tetrominos game by writing its constructor and draw method. Understand managing color indices and drawing blocks with Java graphics to build game components efficiently.

We'll cover the following...

Each falling piece in Tetrominos is made up of four small blocks arranged in a particular way. Let’s write and test the Block class. Create a new file in your project called Block.java. To get you started, here’s a skeleton of the code, which you may copy in:

Block.java
BlockSolution.java
import java.awt.Color;
import java.awt.Graphics;
class Block {
	public int colorIndex;
	public static Color[] colors = {Color.red, Color.blue, Color.magenta,
			Color.orange, Color.green, Color.cyan, Color.yellow};
	public Block(int colorIndex) {
	}
	public void draw(Graphics g, int scale, int x, int y) {
	}
}

Task: write the constructor
