A class is essentially a blueprint for you to To make a class do this: public class Car{ private String color; private String make; private String model; private String engineType; // constructor public Car(String color, String make, String model, String engineType){ // adjust attributes this.color = color; this.make = make; this.model = model; this.engineType = engineType; } // methods public void setColor(String color){ this.color = color; } }
