3 script errors in my code

**aniperi** · June 15th, 2014, 04:13 PM

Hello everyone,

I need to write a simple program. After I input the cost of an entree, drink, and dessert, it should calculate the cost of a meal and its tax. However, when I compile my code, I get three errors. Can you tell me what's wrong and how I can fix it?

Here are the errors I get:

foodcalc.java:1: error: ';' expected
import java.io.*
^
foodcalc.java:2: error: ';' expected
import java.util.Scanner
^
foodcalc.java:13: error: ';' expected
systemout.println ("Enter price of dessert")
^
3 errors

_______________________
And here is my code:

import java.io.*
import java.util.Scanner
public class foodcalc
 
{
  public static void main (String [] args)
  {
  Scanner input = new Scanner (System.in);
  systemout.println ("Enter price of entree");
  double entreeCost = input.nextdouble ();
  systemout.println ("Enter price of drink");
  double drinkCost = input.nextdouble ();
  systemout.println ("Enter price of dessert")
  double dessertCost = input.nextdouble ();
 
  double foodCost = entreeCost + drinkCost + dessertCost;
  double taxAmt = foodCost * 0.10 ;
 
System.out.println ("Total cost is $ " + (int)(mealCost * 100 /100.0));
 
  }
}

error: ';' expected

The compiler was expecting a ; before what it found. Make sure the previous statement has an ending ;

Please edit your post and wrap your code with code tags:
[code=java]

[/code]
to get highlighting and preserve formatting.

Just read the error message:

foodcalc.java:1: error: ';' expected

It says quite clearly, that it expects a semicolon.

import java.io.*;
import java.util.Scanner;
public class foodcalc
 
{
  public static void main (String [] args)
  {
  Scanner input = new Scanner (System.in);
  systemout.println ("Enter price of entree");
  double entreeCost = input.nextdouble ();
  systemout.println ("Enter price of drink");
  double drinkCost = input.nextdouble ();
  systemout.println ("Enter price of dessert");
  double dessertCost = input.nextdouble ();
 
  double foodCost = entreeCost + drinkCost + dessertCost;
  double taxAmt = foodCost * 0.10 ;
 
System.out.println ("Total cost is $ " + (int)(mealCost * 100 /100.0));
 
}
}

After editing my code, it looks like the above^^. However, now I get 7 new errors:

foodcalc.java:9: error: cannot find symbol
systemout.println ("Enter price of entree");
^
symbol: variable systemout
location: class foodcalc
foodcalc.java:10: error: cannot find symbol

systemout.println ("Enter price of drink");

How do I declare the system.out variable? I thought system.out is part of a string, and not a variable to be declared.

How do I declare the system.out variable

System.out is the syntax for referring to the static variable: out in the System class.

Java is case sensitive. You need to check the spelling for any java classes or methods you use.

See the API doc for correct spellings: http://docs.oracle.com/javase/7/docs/api/index.html
