Arrray Error

[slider203]

Hello I made a program that takes a number between 6 and 9 from the user then outputs all days with that number of letters in the name (e.g. 6 monday,sunday,friday)
I have that part working but everytime I run the program It outputs an error after

code:

String[] days_Week = {"Sunday", "Monday", "Tuesday", "Wednesday",       "Thursday", "Friday", "Saturday"};         int[] name_Letters = {6,6,7,9,8,6,8};     int num_Letter = 0;     String input = "";     final int MIN = 6;     final int MAX_COUNT = 9;     final int exit = -1;     boolean numCorrect = false;     do     {       System.out.println ("Please enter a number from " + MIN +" to " + MAX_COUNT+".");       System.out.println ("Enter "+exit+" to end.");       input = br.readLine();       num_Letter = Integer.parseInt (input);             if (num_Letter > exit)       {         // This loop checks if the input is in the array         for (int count = 0; count < MAX_COUNT; count++)         {           if (num_Letter == name_Letters[count])           {             System.out.println (days_Week[count]);             numCorrect = true;           }         }         if (!numCorrect)         {           System.out.println ("Error, input is not a correct number");           System.out.println ("Please try again.");           System.out.println (" ");           numCorrect = false;         }       }     }     while (num_Letter > exit);   } }

You need to post all the source code and also post the error message. Preferably, you'd point out which line the error message lists as well.

Hello DemonWasp that is all of my code the only thing above that is this:

code:

import java.io.*; class arrayPrac4 {   public static void main (String args [])     throws java.io.IOException   {     BufferedReader br = new BufferedReader (new InputStreamReader (System.in));

The error message is:

Quote:

java.lang.ArrayIndexOutOfBoundsException: 7
at arrayPrac4.main(arrayPrac4.java:56)

Thanks for your time

Your for loop runs from 0 to MAX_COUNT, which is 9, but there are only 7 elements in your array. You should be going through based on how many values you're storing, not the maximum value being stored.

Once again thanks Guardian this solved my problem. Im just not understanding arrays at all
