Java array calculation

Would this be the proper way to calculate each elements of an array? The []speed will be import in from a file. There a total of 59 speed thus I have [59]. Then I want to convert the speed ( Which is in knot to mile). I keep getting "java.lang.ArrayIndexOutOfBoundsException: 59"
when I run the program at the line " mile[v] = (int)((speed[v]) * 1.15);" Thanks

Code :

---

    int[] speed = new int[59];
            int[]mile = new int[59];
           for(int v = 0 ; v <= 60;v++)
       {       
           mile[v] = (int)((speed[v]) * 1.15);
       }

---

Array indexes range from 0 to the length-1. The max index for a 59 element array would be 58.
Change the for loop values so the index's value does not go past 58.

If you can't tell what the values are, add a println statement immediately after the for statement that prints out the value of v.

The for statement should use the array's .length attribute to control the looping, not a magic/hardcoded number.

Oh. I forgot the different between length and index. Thanks for the help!
