Creating and using objects

---

• An instance of a class is called an object
• To create an object we use the new keyword
  • You can see the pattern is similar to making a new variable
• Each object is a new instance of the class
  • They keep their own values
• We use the object.method() pattern to use methods inside an object

Example

motor m1 = new motor(0);              //new is used to create an instance of the class called an object
      motor m2 = new motor(1);
      
      System.out.println("m1 channel: " + m1.getChannel());
      System.out.println("m2 channel: " + m2.getChannel());
      
      m1.setSpeed(1);
      m2.setSpeed(-1);

      System.out.println("m1 speed: " + m1.getSpeed());
      System.out.println("m2 speed: " + m2.getSpeed());
