Help on array
Hi, I want to sort an array which contains Strings (sort according to alphabetical order...)
after i sort the array...i want to read it at it's original order too...
that mean's i want to have 2 set of array.....1 with the original order...1 with the sorted order..
how do i do that?
let's say i have a container class Club with an array of Names(type String), and a client class...
with a Club object memberList.how do i do that?
thank you.

OK, how about
ArrayList origArray = ... whatever ...;
ArrayList sorted = new ArrayList(origArray);
Collections.sort(sorted);
Now, origArray still has your data in the original order, sorted has it in the sorted order. Note: both are pointing to the same elements.
Hi,
You can use "System.ArrayCopy" function to create a second array. (Now you have two different set of Arrays)
After that use the following code:
Arrays.sort(strArray);
Where Arrays is your inbuilt class with sort as static function and strArray is the name of the array that you want to sort.
I hope this helps :)
