Question

I have a class which has a String field called name. I have an array of type SomeClass[] and I want to iterate through these SomeClass objects in String order on their names.

I’m curious as to what the most efficient way to do this would be. Should I use a comparator of some sort? Would it be a good idea to put them all into a TreeMap and then iterate through that or something similar? I’m sure I could come up with a solution, but I’m also sure that it would be less than efficient.

Any help is appreciated.

Answer 1

Put your Classes in an Arraylist and use its sort method.
Unverified code:

yourArray.sort(new YourNameComparator());

class YourNameComparator implements Comparator<YourNameClass> {
    int compare(YourNameClass y1, YourNameClass y2) {
        return y1.getName().compareTo(y2.getName());
    }
}
