StringList : sort by custom algorithm

Processing Coding Questions
3

Hi,
It depends on what you want to do, but for the first I would switch from StringList to ArrayList<String> or better as you know that there are existing Files ArrayList<File>.
Afterwards for the latter:

arrayListWithFileObjects.sort((f1, f2) -> Long.compare(f1.lastModified(), f2.lastModified()));

Or if you want to keep Strings (If it is certain that the files exist) you can do s.th. like.

arrayListWithStrings.sort((s1,s2) -> Long.compare(new File(s1).lastModified(), new File(s2).lastModified()));

for the ArrayList<String> version it would be better to go via stream and filter by existence and afterwards do the sort.

PS: The solution above is for Processing (>=4) with java8 support. For older Versions you can use s.th. like:

arrayListWithFileObjects.sort(new Comparator<File>() {
	@Override
	public int compare(File f1, File f2) {
		return Long.compare(f1.lastModified(),f2.lastModified()) ;
	}
});
