newebie question about classes

[me.]

hi all,

new to java and already have difficulties with my code.

having code with two classes:

class Bicycle {
    int cadence = 0;
    int speed = 0;
    int gear = 1;

    		
    		
    void changeCadence(int newValue) {
         cadence = newValue;
    }
    void changeGear(int newValue) {
         gear = newValue;
    }
    void speedUp(int increment) {
         speed = speed + increment;   
    }
    void applyBrakes(int decrement) {
         speed = speed - decrement;
    }
    
    
    void printStates() {
         System.out.println("cadence:" +
             cadence + " speed:" + 
             speed + "  name" + name  
 + gear);
    }
}

and

public class bikes extends Bicycle {
	
	
	    public static void main(String[] args) {

	        // Create two different 
	        // Bicycle objects
	        Bicycle bike1 = new Bicycle();
	        Bicycle bike2 = new Bicycle();
	        // Invoke methods on 
	        // those objects
	        bike1.changeCadence(50);
	        bike1.speedUp(10);
	        bike1.changeGear(2);
	        bike1.printStates();
	        
	        bike2.changeCadence(50);
	        bike2.speedUp(10);
	        bike2.changeGear(2);
	        bike2.changeCadence(40);
	        bike2.speedUp(10);
	        bike2.changeGear(3);
	        bike2.printStates();
	    }
	}

i've been trying to add names to both bikes but dont know how to do it.

tried adding

static String[] name = { "giant", "giant cc"};

to Bicycle class but couldnt display names
than tried to create new class Bikenames with just names as strings but also couldnt get names printed...

can you explain how it must be done,please.
Thank you.

Why do you have an array of names?

See the other variables in the Bike class? You'll need another one to hold the name, and appropriate methods for setting and accessing it.

tried to use arrays but maybe string will do?

String []name ={"Giant ","Giant XXL"};

and appropriate methods for setting and accessing it.

yes :) thats another problem...

[KevinWorkman]

The name needs to be an attribute inside the Bike class. Then you can instantiate a Bike and give it whatever name you want using a constructor or setter method.

tried
bike1.name();
bike1.newname();

and dont even know what else but been playing with it and just cant get it working maybe need break

can you write it as example, please

[KevinWorkman]

You have an example of other attributes inside the bike class. Model what you do off of how it already works. Each bike has a cadence, right? How is that handled?

[me.]

but cadence is integer and names are string
and when I tried using
bike1.names();

was getting error


also

void changename(string newValue)
{ name = newValue;}

didnt work

[Tolls]

You have to realise that "didn't work" is essentially meaningless to us.
You need to provide us with the errors you are getting.

[KevinWorkman]

but cadence is integer and names are string

So? How do you declare a String?

and when I tried using
bike1.names();

was getting error

didnt work

Why would those work? Where do you see a names() method? Or a cadence() method for that matter? You can't just make up syntax and expect it to work. Where did you declare a name variable?
