java errors - what does this mean??

[Kiamari]

class, interface, or enum expected
DVD CLASS
^

class, interface, or enum expected
DVDINVENTORY CLASS
^

HOW DO I FIX THESE TWO ERRORS WITHOUT GETTING OTHER ERRORS???

here is my code:

DVD CLASS


public class Dvd {

private String productNumber;
private String itemName;
private int numberOfUnits;
private double pricePerUnit;

public Dvd(String prodNo, String name, int noUnits, double price) {
productNumber = prodNo;
itemName = name;
numberOfUnits = noUnits;
pricePerUnit = price;
}

public String getProductNumber() { return productNumber; }
public String getItemName() { return itemName; }
public int getNumberOfUnits() { return numberOfUnits; }
public double getPricePerUnit() { return pricePerUnit; }

public double calculateInventoryValue() {
return numberOfUnits*pricePerUnit;
}

}


DVDINVENTORY CLASS


import java.util.Scanner;

public class DvdInventory {

public static void main(String[] args) {
int SIZE = 100;
Dvd[] myDvds = new Dvd[SIZE];
int numberOfDvds = 0;
while (numberOfDvds < SIZE) {
Dvd dvd = readDvd();
if(dvd == null) { break; }
myDvds[numberOfDvds++] = dvd;
}
for(Dvd dvd : myDvds) { System.out.println(dvd); }
System.out.println("Value of Inventory: $ "+calculateInventoryValue(myDvds));
}

private static Dvd readDvd() {
Scanner in = new Scanner(System.in);
System.out.print("Enter item name or \"quit\" to stop: ");
String itemName = in.nextLine();
if(itemName.equalsIgnoreCase("quit")) { return null; }
System.out.print("Enter product number: ");
String productNumber = in.nextLine();
System.out.print("Enter number of units: ");
int numberOfUnits = in.nextInt();
System.out.print("Enter price per unit: ");
double pricePerUnit = in.nextDouble();
return new Dvd(productNumber,itemName,numberOfUnits);
}

private static double calculateInventoryValue(Dvd[] dvds) {
double result = 0;
for(Dvd dvd : dvds) { result += dvd.calculateInventoryValue(); }
return result;
}

}

here is my code:

DVD CLASS
 

I think you should get rid of that preamble. Why did you prepend it to your source
code in the first place?

Remove the lines "DVD CLASS" and "DVDINVENTORY CLASS".

ok, so i did what you said about removing the two lines and now i get these errors:

in the build output window it says: class, interface, or enum expected
import java.util.Scanner;
^
1 error

in the general output window it says: java.lang.NoClassDefFoundError: DvdInventory
Exception in thread "main"
Process completed.

now how do i fix these two errors?

it seems when i try to fix errors...others occur...*sighs*.....is my code not right or something????

I don't know about 'or something' but your code is definitely not right; if the compiler
can't find the Scanner class you either have an old version of Java (older than 1.5)
of you have an installation problem. The other error is just because you wanted
to run a class that didn't even properly compile. You should check your Java
version and if needed upgrade and try again.

Out of interest, eh, where had you placed this import statement? What were the first, say, five lines of the code that gave that error?

its definitely not my java version or installation. i have the latest version 6.0...and the other day i had a program to run perfect.... the problem is somewhere in my code and i just cant figure it out...so i came here in hopes that someone could point me in the right direction or tell me what i have to remove for the code to work.....but it seems everything someone says to remove...another error happens......i thought that providing my code someone could see where i have a few things misplaced or tell me if im missing something....since my code is "definitely not right"..i thought you knew what i had to do to make it "right"

sorry, i dont know what you are asking. after running my code that's the error i get.....for my full code take a look at the previous posts.

There are some characters/words in your .java file that are not part of the code that you want to execute. e.g the line with DVD CLASS.
That is not part of the code and must be removed or commented out. The compiler should see only valid Java statements.

Post the first few lines of that second source file. There must be some text before
the "import java.util.Scanner;" line. And yes, we know what we're talking about
but you're frantically kicking around here and you don't understand our hints and
answers; just stay calm.

there's no text before import.java.util.scanner line....what you saw above was my full code.....until i was told to remove the lines with DVD CLASS and DVD INVENTORY....i reposted the code again with the errors i got after removing those lines.....

btw: i am calm...just waiting for the right answer/help...thats all...

Are you going to post the first few lines of your current code then?
The last code you posted in this thread still has those DVD CLASS things in them.
