Java – Problem with exceptions and arrays

arraysexceptionjava

Can't really understand what's going wrong here?

It's just a simple exception with an array out of bounds.

public class Days
{
    public static void main (String args[])
    {
        String[] dayArray = new String [4];
        {
            dayArray [0] = "monday";
            dayArray [1] = "tuesday";
            dayArray [2] = "wednesday";
            dayArray [3] = "Thursday";
            dayArray [4] = "Friday";

            try
            {
                System.out.println("The day is " + dayArray[5]);
            }
            catch(ArrayIndexOutOfBoundsException Q)
            {
                System.out.println(" invalid");
                Q.getStackTrace();
            }
            System.out.println("End Of Program");
        }
    }
}

Does anybody have any ideas as too why this won't run? I'm getting the error:

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 4
    at Days.main(Days.java:14)

You should declare it as capable of 5 items, not 4, in its declaration.

new String [5];
