I am trying to sort an array of names with this method, more when it has minuscule letter and Acentuo the names go to the end of the list, someone knows a method that sorts considering capital letters , minusculas , with accentuation ?

String nomes[] = { "Ana","aa","B" };
for (int i = 0; i < nomes.length - 1; ++i)  
    for (int j = i + 1; j < nomes.length; ++j)  
        if (nomes[i].compareTo(nomes[j]) > 0) {  
            String temp = nomes[i];  
            nomes[i] = nomes[j];  
            nomes[j] = temp;  
        }
java classification

  • To ignore the uppercase letters there is the compareToIgnoreCase.

  • and the accent you know?

  • In Java if you use an Arraylist you can sort with compareTo. http://www.tutorialspoint.com/java/java_using_comparator.htm

  • you can use the method itself sort() vector to do this.

    In addition, asked the question for array of names, and the right answer is with array of names, if you want to know with Arraylist it would be better to create a new question.

In java you can use an object of the type Collator to make the ordination. Follow an example of use:

Collator brCollator = Collator.getInstance(new Locale("pt","BR"));
public static void sortStrings(Collator collator, String[] words) {
String tmp;
for (int i = 0; i < words.length; i++) {
    for (int j = i + 1; j < words.length; j++) { 
        if (collator.compare(words[i], words[j]) > 0) {
            tmp = words[i];
            words[i] = words[j];
            words[j] = tmp;
        }
    }
}

This way he will order according to our Portuguese.

  • I tried to use with my arraylist public Static Arraylist<Person> sorts(Collator, Arraylist<Person> contacts) { Person tmp; for (int i = 0; i < contacts.size(); i++) { for (int j = i + 1; j < contacts.size(); j++) { if (collator.compare(contacts.get(i).name, contacts.get(j).name) > 0) { tmp=new Person(); tmp = contacts.get(i); contacts.set(i, contacts.get(i); contacts.set(j, tmp); } } } Return contacts; } more when it comes to sorting it just by picking up a contact, you can see pq?

  • Still in trouble? Coming to college I take a look

  • I’m trying to see where I went wrong , this method there works perfectly , more when I switched to accept my Person Arraylist it’s filling everything with just a name

  • I already found where I erred kk , I exchanged a j by i ai was always taking the same name and putting in the place of the other , vlw helped a lot

  • All right, thanks :D

  • @Iigner, when used ArrayList the easiest and efficient way is by using the function sort(List<T> list) of the Collections class... in this way: Collections.sort(listaAOrdenar);

  • yes, I even put in the comment of your question, da uma olhada la :D
