Thread: Error Accessing Array Index

I'm writing code to have the user input entrees served on certain days. The error is coming in when I ask the user to search for a certain entrée so I can output the day it's served.

The error I'm getting is java:39: cannot find symbol for this line:
System.out.println(food+" is served on " +day[index]);

symbol: variable index

I accessed the day index earlier in the code without errors, so I'm not sure what's wrong.

import java.util.Scanner;
 
public class Assignment3
{
   public static void main(String[] args)
  {
   //create scanner object
   Scanner sc = new Scanner(System.in);
   String food;
 
   //create day array
   String[] day = {"Monday", "Tuesday","Wednesday", "Thursday", "Friday"};
 
   //create entree array
   String[] entree = new String[5];
 
   //create price array
   double[] price = new double[5];
 
   //prompt user for input for entree
   for(int index=0; index < day.length; index++)
   {
   System.out.println("What entree is being served on " +day[index]);
   entree[index]=sc.next();
   }
   //prompt user for price
   for(int index=0; index < entree.length; index++)
   {
   System.out.println("What is the price for "+entree[index]);
   price[index]=sc.nextDouble();
   }
   System.out.println("Enter an entree to search for:");
   food=sc.next();
   System.out.println(food+" is served on " +day[index]);
 
	//Find the highest priced entree
	double max = price[0];
	for(int index=1; index < price.length; index++)
	{
	//examine the current element in the array
	//determine if it is larger than the current max
	if(price[index]>max)
	  {
	   //if so, replace the current max
	   max = price[index];
	  }
	}
	System.out.println();
	System.out.println("The most expensive entree is " +max);
   }
}

That's the problem, the slot will be determined by user input when they search for an entrée.
