Java Arraylist

[HALEN666]

How would you sort in ascending order an arraylist in java. In other words. You have an arraylist (list1) nwith random values, how would you put those values in ascending order in a second arraylist(list2)?

I have all the code, but I can get that part working, it is a logic error. Help please

There are a number of well known sorting algorithms that have been developed by mathematicians and software developers (or computer scientists if you want to have an impressive title). Pick one, they all work, some work better that others for different things.

I forgot to mentiones. I am not allowed to use any sorting method, such as sort, bubble sort, binary sort, etc. I pretty much have to compare each element in the array and put it in their correct place. I have spend 2 hours trying to figure it out and still can't get it to work.

So you're not allowed to use a sorting algorithm, yet you have to sort?

Are you sure it's just that you can't use predefined algorithms?

You could use the sort method from java.util.Collections, but that still uses a sorting algorithm.

Hi!

I just took a course in Java programming at University, and at the same time we discussed the sorting algorithms in Math, Big O, Small O and so on, for all Mathematicians out there. ;)

I think your assignment is to Write a sorting algorithm without using already implemented functions.

I'd say, try to program one of the easier sorting algorithms, you can find tutorials on them out there as well.

I'd recommend looking at wikipedia, they usually have pseudocode aswell.

Hmmm if you need help programming the stuff, just send me a pm or write it in here.

I'm glad to help ;)

PS: Sorting is always an algorithm of some sort to be precise.

Yeah what you're looking to do is VERY similar to bubblesort and other sorting algorithms, and is probably the better way to do it.
