Dear Ranchers,
I'm using JSP and MySQL for my project. In that I'm using a third-party graph tool which reads the chart data in String array and the chart value in double array.
I've all my database values stored in a linklist and i want to convert the link list to a double array and a String array

The code is given below



Where ex_cnt is the chart value which should be in double and ex_code is the chart data which should be in String.

Please help me ranchers to sort out this.

Thanks in advance

regards

You haven't told us what type of objects your LinkedList contains, nor precisely what you want to convert them to. I see you converting the list contents to a double[] and also to a String[] -- which is it? And what's actually in the LinkedList? Double? String? Something else?

Recall that Java is a "strongly typed" language, and conversions from one data type to another usually must be done explicitly.
