• Java is case-sensitive
• Create an object (instance of a class) with 'ClassName newObject = new ClassName();' format
• Can invoke methods on objects with 'objectName.methodName();' format
• Methods are like functions/algorithms, you can store them in separate files and then call them in main file
• When doing so remember to extend the class
• if/while loop parameter format is 'if/when (objectName.condition())'
• Pay attention to indentation and formatting. Organization is key not only for compiling but also for human readability

import org.code.neighborhood.Painter;

public class MyNeighborhood {
  public static void main(String[] args) {
   // constructing an instance (object)
    Painter myPainter = new Painter();
    // how to use a method with an object
    myPainter.move();
    myPainter.takePaint();

    myPainter.turnLeft();
    myPainter.turnLeft();
    myPainter.turnLeft();

    myPainter.move();
    
  }
}

import org.code.neighborhood.Painter;
// separate methods in PainterPlus file
public class PainterPlus extends Painter {
  public PainterPlus() {
    super();
  }
  // turnRight is actually rotating left 3 times
  public void turnRight() {
    turnLeft();
    turnLeft();
    turnLeft();
  }
  // using if and while loops, parameter format is 'objectName.givenCondition()'
  public void takeAllPaint() {
    if (myPainterPlus.isOnBucket()) {
      while (myPainterplus.isOnBucket()) {
        takePaint();
      }
    }
  }
  // mind indentation/formatting for code in method
  public void paintLine(String color) {
    while (myPainterPlus.canMoveForward()) {
      paintColor();
      myPainterPlus.moveForward();
    }
