Adding a Restock Fee

[nexcompac]

I am getting I believe three erros in this code. I had it running perfect untill I added all the restock fee items.

This is what I have so far:

import java.util.*; // program uses class Scanner
 
public class Inventory 
{    
    // main method begins execution of Java application
   public static void main( String args[]) 
   {    
      product[] myProduct = new product[5];      
 
        product p1 = new product("Tom Clancy Vegas", 20003, 5, 30);
        product p2 = new product("Froger", 74512, 2, 10);
        product p3 = new product("Halo 2", 20009, 3, 45);
        product p4 = new product("Night Caster", 74522, 8, 5);
        product p5 = new product("Halo 3", 32976, 1, 50);
 
        myProduct[0] = p1;
        myProduct[1] = p2;
        myProduct[2] = p3;
        myProduct[3] = p4;
        myProduct[4] = p5;
 
        double totalValue = 0.0;
 
        for (int c=0; c < 5; c++)
        {
            totalValue = totalValue + myProduct[c].itemCalculate();
        }
 
        Arrays.sort(myProduct); // function used to sort arrays
 
        for(product p: myProduct)
        {
            System.out.println(p);
            System.out.println();
        }
       System.out.println("Total Inventory value is: $"+totalValue);
 
   } //end main
 
} //end Inventory
 
 

The above works fine, the errors appear here below (I think because I only changed the below and got errors.

Hi,
So here u posted the right code......see ur errors......compiler is not able to find value() method.......... coz there is no value() method in ur product(name it --Product *always start a class name with block letter only*) class...... so check it again

thanks and regards,
madhoriya

[nexcompac]

I am not sure that was the issue. If I take out these lines:

***************
public double RestockFee() // Method to set the Restocking fee
{
return value() * 0.05;
} // end
***************
public double setRestockFee() // Method to set the Restocking fee
{
return value() * 0.05;
}
public double getRestockFee() // Method to set the Restocking fee
{
return value() * 0.05;
}


Code will run fine.

Where is the definition for the method value() ?

Hi,
luk at ur getRestockFee() method again........ here u r calling value method in ur return statement..... but there is no value method in ur class.....thats why compiler is not able to resolve it... it is not wise to remove the lines where u r getting errors...... instead u should think what u need to resolve this error.... I think r035198x has given u the answer.....define value() method in ur class

thanks and regards,

I find those previous error diagnostics very suspicious:

Product.java:61 cannot find symbol
symbol : method value<>
location: class product
return value<> * 0.05;
 

Look at those angular brackets while the code itself seems to use ordinary
parentheses. Something's rotten in the state of Denmark here.

Looks suspicious indeed.
I ignored it thinking that maybe the OP is using a funny text editor that uses different characters for normal code pages and error output windows.

Hi,
I thought he has written the errors himself instead of just copy pasting it......that why he has done the typing mistake..... not so sure ? bcoz my compiler is showing it right..

product.java:60: Method value() not found in class product.
        return value() * 0.05;

In reguards to the fishy smell, cant help you with that. Try lysol. About the error. I have been trying to compile from the bin folder using the comand prompt. Since I am unaware how to copy and paste from the CMD, I just typed it out.

I am very new to this and my work computer will not let me install the jdk on it without admin access. I could install it if I REALLY needed to, but it is not worth getting in trouble over. =)

Eh, do you mean to say that you compiled that code without the JDK?

Try using Textpad. You can compile and run certain programs from it.

P.S Are the errors gone now?

[JosAH]

Lol!

Jos :-)

[r035198x]

Lol!

Jos :-)

I just googled it.
Silly me

[nexcompac]

You googled Lysol? Funny....
For some reason I am having troubles with TextPad and the way it complies on my home computer. My laptop works just fine, but I can not use it at work. My work computer does not have permission to install the JDK files and its not worth "tweeking" it at the moment. So, I need to wait until I get home unless you have a way of doing it without requireing the Admin password.

About the complie stuff. Since my computer has issues, I copy the *.java files into the bin folder of the JDK and then compile from the comand prompt by changing the directory to the bin file and typing javac *.java. This will compile all the java files and give me the *.class files. Then, I can just fire the java files from the cmd too. Does that make sence?

It sort of works but you shouldn't do it like that: add the name of that bin directory
to your 'path' environment variable and store your .java sources and .class files
somewhere else in their own directory. You don't pollute that bin directory then.

Ok, so should this be defined in the current class which it resides in or should it be designed in the public main class?

Heres what someone pointed out to me.

And your problem is that you did not and still have not defined a value() method. Typically, methods need to exist before you use them

That is ever so true; I tried to find the definition of the value() method in your
post but it was nowhere to be found. Define a method value() in your class:

double value() {
   return //whatever it has to return
}
 

and try again.

That is ever so true; I tried to find the definition of the value() method in your
post but it was nowhere to be found. Define a method value() in your class:

double value() {
   return //whatever it has to return
}
 

and try again.

Ok, so what is the best method in proceeding to add the GUI to this?

I don't know; I don't know what sort of GUI you have in mind. Have you read
about the Swing framework? Look here.

I just went through that class. Get ready to rewrite your entire primary class.
It is fun. :o)
