New to Java .....help please....be nice too!

[johnb082]

Yes I posted earlier. Researched what I could find on "proper indenting" and couldn't find anything helpful! I receive one error in CoffeeDriver class. Item class compiles. The error I receive is in the creation of the Array. Item is defined in the Item class. I compile Item before trying to compile CoffeeDriver.

Error is: cannot find symbol
symbol : variable Item
location: class CoffeeDriver

Many thanks!

import java.util.*;
import java.util.ArrayList;
import java.util.Comparator;

public class CoffeeDriver {

		//main method
    		public static void main (String[] args){
      	        Scanner input = new Scanner(System.in);
                String decision;
			
		//Create the Array
		Item[] items = Item[5];
			
		items[0]= new Item("Coffee",1.00);
		items[1]= new Item("Water",2.00);
                items[2]= new Item("Milk",1.50);
 		items[3]= new Item("Donut",0.75);
 		items[4]= new Item("Bagel",1.25);

         System.out.println ("Welcome to Wings Coffee Shop");
         System.out.println ("We have a great list of tasty items on our menu.");
         System.out.println ("Would you like to see these items sorted by");
         System.out.println ("name or by price? (n/p): ");
         decision = input.nextLine();
            if (decision == "n"){
                sortName(items);
                }
            else 
                sortPrice(items);

Where is the definition for the Item class? What folder is it in? What folder is the CoffeeDriver class in?
The compiler can't find the definition for the Item class. Are any of the classes in a package?

Here is a suggested formatting for your code. Line up { or code with the { with the ending }.
Put all code in a pair of {} in column alignment.

	//main method
    	public static void main (String[] args){
      	        Scanner input = new Scanner(System.in);
                String decision;
			
		//Create the Array
		Item[] items = Item[5];
			
		items[0]= new Item("Coffee",1.00);
		items[1]= new Item("Water",2.00);
                items[2]= new Item("Milk",1.50);
 		items[3]= new Item("Donut",0.75);
 		items[4]= new Item("Bagel",1.25);

               System.out.println ("Welcome to Wings Coffee Shop");
               System.out.println ("We have a great list of tasty items on our menu.");
               System.out.println ("Would you like to see these items sorted by");
               System.out.println ("name or by price? (n/p): ");
               decision = input.nextLine();
               if (decision == "n"){
                  sortName(items);
               }
               else 
                  sortPrice(items);         
    	}//End main()

Hello

Item class and CoffeeDriver are both in the same folder of c:/java/. I have tried to verify that each { had a corresponding }. Is there a particular rule for what kind of statement gets a }? If so, where does it end with {? How do I tell if there is a package? I didn't code a package. Does that matter?

I reformatted your code to have indent according to convention. maybe comparing the two will help you understand. It may not seem important to you now, but the more you code, the more you will realize the importance of adhering to convention.

note: I tried to do this in the text box of the website so it may not be perfect

import java.util.*;
import java.util.ArrayList;
import java.util.Comparator;

public class CoffeeDriver {

        //main method
    	public static void main (String[] args){
      	        Scanner input = new Scanner(System.in);
                String decision;
			
		//Create the Array
		Item[] items = Item[5];
			
		items[0]= new Item("Coffee",1.00);
		items[1]= new Item("Water",2.00);
                items[2]= new Item("Milk",1.50);
 		items[3]= new Item("Donut",0.75);
 		items[4]= new Item("Bagel",1.25);

                System.out.println ("Welcome to Wings Coffee Shop");
                System.out.println ("We have a great list of tasty items on our menu.");
                System.out.println ("Would you like to see these items sorted by");
                System.out.println ("name or by price? (n/p): ");
                decision = input.nextLine();
                if (decision == "n"){
                     sortName(items);
                }else{ 
                     sortPrice(items);
                }         
    	}//End Main

	//method to sort by item name and display
    	public static void sortName (Item[]r){
             for (int i = 0; i < r.length; i++){
                 System.out.println (r[i].toString());
             }
   	 }//End Sort by itemName

	//method to sort by item price and display
    	public static void sortPrice (Item[]r){
            for (int i = 0; i < r.length; i++){
                 System.out.println (r[i]);
            }
         }//End Sort by itemPrice
}//End Class

If both the Item.java and the CoffeeDriver.java files are in the same folder and neither has a package statement,
I don't know what to recommend. Do you have the Item.java file or just the Item.class file? If you don't have the Item.java file how do you know if the Item class is in a package or not?

[johnb082]

Item.java and CoffeeDriver.java are in the same folder. There is an Item.class file as well. The Item class looks like this:

public class Item{
 
				//A String instance variable for the item name 
				private String itemName; 
				
				//A double instance variable to hold the price 
				private double itemPrice; 
 
				//A constructor that takes a String and double to initialize the instance variables 
 				public Item (String n,double p){
				itemPrice = p; 
				itemName = n;
				} 
												
				//Getters and setters methods for each instance variable 
 				public void setItemName(String n)
				{ 
				itemName=n;
				}
								 
				public void setItemPrice(double p)
				{
				itemPrice=p; 
				} 
				public String getName()
				{ 
				return itemName; 
				} 
				public double getPrice()
				{ 
				return itemPrice; 
				} 
 
}//end class

Thank you very much YellowLedBet. That helped me organize it better. Still receive errors though.

[Norm]

Still receive errors though.

Please post the full text of the error message.

[Norm]

The code with a pair of {} should be indented:

                          public Item (String n,double p){
				   itemPrice = p; 
				   itemName = n;
			  }

Researched what I could find on "proper indenting" and couldn't find anything helpful!
