// toString public String toString() { return year + " " + make + " " + model; } } : this is used in the constructor and setters to distinguish between the parameter and the instance variable. It’s not required if you use different parameter names (like carMake ), but this is a clean, standard practice. Testing Your Class CodeHS usually provides a CarTester or Main class. If you want to test manually, you could add a main method inside a separate class or temporarily inside Car :
// Getter for year public int getYear() { return year; } These allow you to change the values after the object is created. 5.6.7 Car Class Codehs
public String getModel() { return model; } // toString public String toString() { return year
