Problem adding a object to an array

[AZRebelCowgirl73]

here is the instructiions I am to use

Ask the user to input the number of effective cars in the shop (this number should be between 1 and 100, inclusively). In a loop, controlled by the inputted number of effective cars, ask the user to input each car data (i.e. make, model, year and price). You can assume that all input data is correct and no data validation is necessary. As soon as all input data for a car is entered, build a Car object by the constructor with parameters and then save the Car object in the array.

Here is what i have so far:

I'm not to sure if you can use a array this way. I think you need to use a Arraylist. You can make an index stop at 100 if an if statement but why?
When you have this code

 Car C = new Car(m, d, y, p);

For example you can have an array of intergers, an array of string Objects, or an array of arrays, but you can not have an array that contains both String Objects and integers.

Also you have a mistake in.

 
System.out.print("What is the make of your car? ");    
            String m = stdin.nextLine();
            System.out.print("What is the model of your car? ");
            String d = stdin.nextLine();
 

Delete the Line, should look like this:

 String m = stdin.next();

otherwise you will get
What is the make of your car?What is the model of your car?
and that not what you want.

First of all, from now on please try to use [ code ][ /code ] (without spaces) brackets around your code.

I'm curious... what do you want it to print? All of the data in car, one at a time? All I know is that right now you're trying to print a car(m, d, y, p). Since this is not a string it simply prints the classname@locationInMemory, understand? If you want it to print everything (since you already have a print method in car) you should replace the following line:

"System.out.println(carShop[i]);"

with

"carShop[i].print();"


Hope that solved your problem,
-blazed

[shanakard]

System.out.println(carShop[ i ]);

in the above line u have given a Object of type Car to the println() function
this will run the "println(Object v)" overload of the println function and take the given parameter as a "Object" type parameter.

when any object 'x' is given to println() function it will print the output string of the x.toString() function to the console.

since every class is derived from the Object class and Object Class has a toString() method that prints the class Type of the object and it's memory address it will be output. (like Car@14318bb).

if U want to output the car information for that object U should Overload the toString() method in your Car class.

(for more information read the Object class's toString() function of the java documentation)

Hopes this solves ur problem.

}

Ok now when I run this program I get it to print out each object within the carShop[] array, however when the loop is running it duplicates the last run loop for each object in the array. what I mean to say is this. Say I run the loop 2 times for 2 cars, and i put honda, accord, 1999, $14000 for the first run of the loop for the first car and i put toyota, corolla, 2001 $17000 for the send run of the loop for the second car. When the array dat prints, carShop[0] shows toyota, corolla, 2001, $17000 and carShop[1] shows toyota, corolla, 2001, $17000, it skips the first instance of the loop.

I am not allowed to change the Car.java file.
I also can not use anything but the main() method in the CarDealerApp.java file.

Can anyone help me with what I may be missing! Thanks in advance ALI :P

you are reinitialized the arrary
This will print after each loop

Delete this part

 carShop = C; 
System.out.println();
} 
for (int i= 0; (i < numberOfCars) && (i < MAX_SIZE); ++i) {
carShop.print();
 } 
 }
 } 
 

add this part

carShop[i] = C;

System.out.println();

Car.Carprint();

}

}

After the loop is finished is when I am suppose to create a instance that prints the contents of the carShop[] array? adding the section you suggested would print each loop as it finished and that would be insufficient for the exercise! Any other ideas and Thanks so much for the help! ALI :P

[shanakard]

public class Car{
public static String make;
public static String model;
public static int year;
public static int price;
//Car(); constructor with parameters
public Car(String m, String d, int y, int p) {
make = m; ...... 

U see the above code all the attributes of the class Car are "static" (i.e:- public static String make)

the thing with static variables are it only keeps one memory location to keep it's data for all the instances of that class. this could be used in cases to count the number of instences of a class (as shown in bellow code) like thing or many other uses.... Actually static variables are an important concept when we wan't to share data among all instances of the same class;

public class Test{
   private static int count;
 
   public Test(){
       count+=1;
   }
 
   public void finalize(){
       count--;
   }
 
   public static int getCount(){
        return count;
   }
 
   public static void main(String[] args){
       Test a,b,c;
 
       System.out.println("Count before any object is created is "+Test.getCount());     //don't need a instance of the class to access static variables
       a=new Test();
 
       System.out.println("Count after 'a=new Test()' is "+Test.getCount());
       b= new Test();
       c=new Test();
 
       System.out.println("Count after 2 new objects are created is "+c.getCount());    //In java we can also use a instance of the class to access static members
       //if u ever used Integer.parseint() method haven't u wondered where the Integer part came from, obviously it's not any object u created. actually it's a static method in Integer class'
 
       a=null;
       System.gc();  //invokes the garbage collector
 
       System.out.println("Count after object pointed to by 'a' is destroied is "+Test.getCount());
   }
 
}
 

in ur example since the Car classes members are static they only keep a single set of data for all the instances of the car objects.
so unless u change the car class what u request is not possible in java !!!

hope this helps U ;-)

You are my HERO :)) Thanks so much! But now I face a new problem!
Thanks so MUCH!!!! ALI :P

[AZRebelCowgirl73]

Here is my problem:

I have two java files:

One named Car.java and the other named CarDealerApp.java: In the CarDealerApp program, I read in through user input the make, model, year and price of a car and put them into an array called carShop[]. This part of the program is running fine. Every thing in the CarDealerApp.java file runs correctly except for the last loop. I need to read in through user input the make of a car and then search the array carShop[] for the make and subtract $1000 from the price listed for all instances of that particular make within the array. I cant seem to make the code work, the user input part does but the for loop does not! Can anyone help! Here is what I have so far: Thanks in advance!! ALI :P

Here is my problem:

I have two java files:

One named Car.java and the other named CarDealerApp.java: In the CarDealerApp program, I read in through user input the make, model, year and price of a car and put them into an array called carShop[]. This part of the program is running fine. Every thing in the CarDealerApp.java file runs correctly except for the last loop. I need to read in through user input the make of a car and then search the array carShop[] for the make and subtract $1000 from the price listed for all instances of that particular make within the array. I cant seem to make the code work, the user input part does but the for loop does not! Can anyone help! Here is what I have so far: Thanks in advance!! ALI :P

When you are searching for a model is their a particular model you are looking for. If not then it all you have to do is minus 1000 for all models.
Search for just the model of the car then print that model with the price minus 1000.

No I actually have to ask the user to input the model to search for then reduce the price by $1000. The price reduction only appliees to the car make inputted by the user. Thanks!!!! ALI :P
