这是最佳方法的简单Java示例：
import java.util.ArrayList;import java.util.Collections;import java.util.Comparator;import java.util.List;public class Sorter { String fruits[] = new String[7]; List<String> lst; Sorter() { lst = new ArrayList<String>(); // initialise UNSORTED array fruits[0] = "Melon"; fruits[1] = "apricot"; fruits[2] = "peach"; fruits[3] = "mango"; fruits[4] = "Apple"; fruits[5] = "pineapple"; fruits[6] = "banana"; } public static void main(String[] args) { Sorter srt = new Sorter(); srt.anyOldUnstaticMethod(); } public void anyOldUnstaticMethod() { Collections.addAll(lst, fruits); System.out.println("Initial List"); for (String s : lst) System.out.println(s); Collections.sort(lst); System.out.println("nSorted List"); for (String s : lst) System.out.println(s); Collections.sort(lst, new SortIgnoreCase()); System.out.println("nSorted Ignoring Case List"); for (String s : lst) System.out.println(s); } public class SortIgnoreCase implements Comparator<Object> { public int compare(Object o1, Object o2) { String s1 = (String) o1; String s2 = (String) o2; return s1.toLowerCase().compareTo(s2.toLowerCase()); } }}
