Thread: 1 error???

i keep on getting the same error again.

i was wondering if someone could kindly take the time to look over this simple error, please.

it says:
: variable i might not have been initialized
while(i<=5)
^
1 error

Process completed.


my program is:

import java.lang.String;
import java.util.Scanner;
public class WeCanWorkItOut
{
    public static void main(String[] args) 
    {    
    Scanner input=new Scanner(System.in);
    System.out.println("Please enter a number");
    double num1=input.nextDouble();
    System.out.println("Please enter a second number");
    double num2=input.nextDouble();
    System.out.println("Please enter a third number");
    double num3=input.nextDouble();
    System.out.println("Please enter a fourth number");
    double num4=input.nextDouble();
    System.out.println("Please enter a fifth and final number");
    double num5=input.nextDouble();
 
    if(num1<num2)
    if(num2<num3)
    if(num3<num4)
    if(num4<num5)
    {
    System.out.println(" The first number entered is the smallest number. ");
    }
    else
    {
    System.out.println(" Some of the numbers might be incorrect. " 
    					+ " Enter other numbers. ");
    }
 
 
 
 
    if(num1>num2)
    if(num2>num3)
    if(num3>num4)
    if(num4>num5)
    {
    System.out.println(" The first number entered is the largest number. ");
    }
    else
    {
    System.out.println(" Some of the numbers might be equal. ");
    }
 
 
    if(num1<=num2) 
    if(num2<=num3) 
    if(num3<=num4)
    if(num4<=num5) 
    {
    System.out.println(" There isn't a number with the lowest value as some or all of these numbers may be equal. ");
    }
    else
    {
    System.out.println(" Try entering other numbers. ");
    }
													// indefinite= greater than or equal to //											
    if(num1>=num2)
    if(num2>=num3)
    if(num3>=num4)
    if(num4>=num5)
    {
    System.out.println(" There isn't a number with the highest value as some or all of the values may be equal. ");
    }
    else
    {
    System.out.println(" Try entering other numbers. ");
    }
 
    double average;
    average= (num1+num2+num3+num4+num5)/5;
    System.out.println ("Average:"+average);
 
    int largest=Integer.MIN_VALUE;
    int smallest=Integer.MAX_VALUE;
    int compared=0;
    int i;
    Scanner scan=new Scanner(System.in);
    while(i<=5)
    {
    	System.out.println ("Please enter a value.");	
    	compared=scan.nextInt();
 
    if(compared>largest)	
    {
    	largest=compared;
    }
    if(compared<smallest)
    {
    	smallest=compared;
    }
 
 
    i++;
    }
    System.out.println (smallest);
    System.out.println (largest);
 
    }
 
}

i did that several times and then i got two errors so what should happen?

int i = 0;
