Out of bounds error with an array.

Question

Dear all,
java.lang.ArrayIndexOutOfBoundsException: 1
I keep getting this error message when I try and use a for loop to step through an array of which the upper bound is 'count'.
I feel as if I have tried all permutations of spelling out the possible values of the vertices, using .length etc but all to no avail.
Here is one bit of code that is getting this error:
public String toString(){
        int i = 0;
        for (i = 0; i == count; i++);{
            System.out.println (+  vertices.getX() + + vertices[i].getY());
return "";
The reason for the return "" is to get rid of another error that used to say no return value.
I'll happily try any suggestions, I just want to get my program working.
Thanks
PS I have read through the recent postings on this but I can't see how they answer my query.

Answer 1

Thanks for spotting the semi colon in the wrong place it seems to have sorted out that bit, but I've now got another array out of bounds exception 0 on a different bit.
public double perimeter (){
        double perimeter = 0;
        //int i = 0;
        for ( int i = 0; i < (count -1) ; i++){
        perimeter = perimeter + ( vertices.distance(vertices[i + 1]));
perimeter = perimeter + ( vertices[0].distance(vertices[count]));
return perimeter;
This bit of code is supposed to calculate the perimeter of any polygon. So my algorithm was to start at vertices[0] use the distance method to calculate the distance between that one and the next one all the way up to the last one in the array vertices[count]. And then calculate the distance from the first vertice to the last and add that on to make the total.
The line that is being spat out is
perimeter = perimeter + ( vertices.distance(vertices[i + 1]));
I can't see why.
