Making our own class

---

• Each class gets a unique name.
• Classes can contain variables.
  • Classes can also contain objects of classes as well
• The constructor is a method with the same name as the class
  • The constructor doesn’t return any type and doesn’t declare void either
  • This is the method called when new is used to create an object

---

Example

//Simple motor class
class motor{
    //classes can have fields that store data
    int channel;                //which port is the motor connected too
    double speed = 0;           //how fast should the motor be going -1 to 1

---

• A class can also have it’s own methods
• Methods that return a single value are called getter methods
• Methods that send values to variables are called setter methods
• More complicated methods also exist in classes

Examples

 motor(int c){               //This is the constructor, it doesn't have a return type or void
        channel = c;            //channel doesn't get a value set until the consttuctor is run
    }
    
    int getChannel(){          //this is a "getter" method it returns a value
        return channel;
    }
    
    double getSpeed(){          
        return speed;
    }
    
    void setSpeed(double s){    //this is a "setter" method it sets a value
        speed = s;
    }
