Using if to print words

I am trying to make it so that 0 is the equivalent to a closed door and 1 is the equivalent to open. My problem is that I have it set at the moment to print 0 or 1 depending on which Demo I run but I am looking for a way for it to print Closed if the value is 0, and open if the value is 1. Can some help me out please. :D

Code:

class Car {

        int gear = 0;
        int speed = 0;
        int RFdoor = 0;
        int LFdoor = 0;
        int boot = 0;
        int bonet = 0;
       
        void changeGear(int newValue){
                gear = newValue;
        }
       
        void speedUp(int increment) {
                speed = speed + increment;
        }
       
        void applyBrakes(int decrement) {
                speed = speed - decrement;
        }
       
        void openRFdoor(int increment) {
                RFdoor = RFdoor + increment;
        }
       
        void closeRFdoor(int decrement) {
                RFdoor = RFdoor - decrement;
        }
       
        void openLFdoor(int increment) {
                LFdoor = LFdoor + increment;
        }
       
        void closeLFdoor(int decrement) {
                LFdoor = LFdoor - decrement;
        }
       
        void openBoot(int increment) {
                boot = boot + increment;
        }
       
        void closeBoot(int decrement) {
                boot = boot - decrement;
        }
       
        void openBonet(int increment) {
                bonet = boot + increment;
        }
       
        void closeBonet(int decrement) {
                bonet = bonet - decrement;
        }
       
        void PrintStates() {
                System.out.println("Gear:" + gear +
                "  Speed:" + speed +
                "  Right-Front Door:" + RFdoor +
                "  Left-Front Door:" + LFdoor +
                "  Boot:" + boot +
                "  Bonet:" + bonet);
                }
        }

Write a small method that takes the value as an argument and returns a String: "Closed" if the value is 0, and "open" if the value is 1

Would you be able to write me an example of such code as I am relatively new to Java and I am unsure how to do what you are saying.

Take a look at the tutorial:
Defining Methods (The Java™ Tutorials > Learning the Java Language > Classes and Objects)

What part don't you understand:
write a method that returns a String
pass it the value as an argument
test the value of the argument and chose a String to return
return a String

Could you possibly give me an example as I am not sure how to use this in my situation.

Do you know what a method is? Have you called a method in any of your code?
The posted code has many methods defined in it. None of them return a value.
Here's how you'd have one return a value:

Code:

---

    int speedUp(int increment) {
        speed = speed + increment;  //  compute the new speed
        return speed;                      //  return the new speed
    }

Do you not understand if-statements, or do you not understand how to define a method?

Why would I need to get a return of speed?

I think he was just demonstrating how to return a value.

Can you clarify what you don't understand?

All i want is to implement the if statement so that when I run my CarDemo.class file rather than returning a 0 or 1 it will return closed or open.

Then this is what you should read: The if-then and if-then-else Statements (The Java™ Tutorials > Learning the Java Language > Language Basics)

it will return closed or open.

What method in the CarDemo class is returning a value? I don't see any methods in the posted code that return a value.
Do you mean prints the value?

How much of the tutorial at the link I posted did you read? There is a lot of material there on methods. For example:
http://docs.oracle.com/javase/tutori...turnvalue.html

I use System.out.println to get a value back in the CarDemo.

to get a value back

It's a vocabulary problem.
The println method does NOT return any value. It writes a String to the output target which is the console.
A method uses the return statement to return a value.

I may have confused you, I use println to show me the value of the gears etc once the Demo had ran. My problem is that Right-Front Door etc are being showed as 0 or 1 and I want to the print to show them as open or closed, I am trying to use the if and else if to help my println show closed and not 0.

Ok, so you want to use an if-else statement.

I have tried to implement an if else statement but I keep getting a lot of errors, 20 at the moment. I was wondering if you could give me an example of what code I should use where because this seems to not currently be working correctly. :(

you can use an inline if:

Code:

---

"  Right-Front Door:" + ((RFdoor == 0) ? "Closed" : "Open") +

---

What errors are you getting when you try the if-else statement?

You Sir, are an absolute genius! Could you briefly explain the code possibly. It worked and did everything that I wanted it to. I just need to know how it works please. :)
