You can either create two booleans named off and on. Or if you're just trying to get the System.out.println to say off and on, and you created a bulb class with isOn boolean variable, do something like if(myBulb.isOn) System.out.println( The bulb is on); else System.out.println(The bulb is off); Can't see your code so not exactly sure what you are trying to do, hope this helps

this is what i have: public class bulb { private boolean state; public bulb() { state = false; } public void turnOn() { state = true; } public void turnOff() { state = false; { public String toString() { return "Bulb is" + state; } }

Sorry, I want to help you. but you're not making much sense on what it is you're actually trying to do. Instantiate means to create an object, if you want an object created depending on off or on, you just create an if statement. if(isOn) Object obj = new Object(); Since I don't think that's what you actually mean, you'll need to clarify a bit more
