Hi am trying to get the elements in array list by passing the indices.


If "to" is equal to the size of the list.,then only the exception is coming ..


I checked the Index as list.indexOf(det), then it shows the last inde Index as 13 and size of the list as 14..
Please give me solution..

thanks

Lists (like Java arrays) are zero based indexing... i.e the first element's index is zero

There are methods in the List interface which provide the size of the List; it is easy to use that size - 1 to access the last element.
You can get nasty out-by-one errors if you use <= instead of < (or vice versa) in a for loop.
 
I agree. Here's the link: http://aspose.com/file-tools
