Code.org Completion

I have completed Code.org unit 1! Here I will share some of what I have learned.

public class PainterPlus extends Painter{
    public PainterPlus() {
      super();
    }
    public void turnRight() {
      turnLeft();
      turnLeft();
      turnLeft();
    }
    public void move(int blocks) {
      for(int i = 0; i < blocks; i++) {
        move();
        paint("white");
      }
    }
}

In this example, 'PainterPlus' is a subclass of the superclass 'Painter'. PainterPlus extends Painter, meaning PainterPlus inherits the characteristics of the preset class Painter. With this subclass, I can create constructors and methods to alternate the actions of the Painter.

Lines 2 and 3 represent the constructor signature. Constructors are a special type of method invoked to create objects from a class.

'turnRight' and 'move' represent methods, or blocks of codes that only run when called upon.

public class MyNeighborhood {
    public static void main(String[] args) {
  
      // Lesson 6 Level 3
      // TO DO #1: Instantiate a PainterPlus object.
      PainterPlus myPainterPlus = new PainterPlus();
      
      myPainterPlus.move(3);
      myPainterPlus.turnRight();
      myPainterPlus.move(2);
      
  
      // Lesson 7 Level 2
      // TO DO #1: Navigate the PainterPlus object
      // to the traffic cone.
      
      
    }
  }

Here, I have instantiated an object called "myPainterPlus", which has a behavior displayed upon by the objects. The object follows the given commands written below it.
