) and the parameter passed in to the constructor (shipType
) share the exact same name. When you have a naming conflict like that you have to use the this
keyword when referring to the member variable in order to help Java distinguish it from the name of the parameter. Like this:
public Spaceship (String shipType) {
this.shipType = shipType;
}
