使用Comparetor的小排序

    List<String> l1=new ArrayList<String>();
        l1.add("A");
        l1.add("b");
        l1.add("D");
        l1.add("c");
        Collections.sort(l1);
        System.out.println("A,b,D,c的默认排序：");
        Iterator<String> x1=l1.iterator();
        while(x1.hasNext())
        {
            String obj=x1.next();
            System.out.println(obj);
        }
        System.out.println("A,b,D,c的不区分大小写字母排序");
        Collections.sort(l1, new Comparator<String>() {
            public int compare(String x,String y)
            {
                return x.toLowerCase().compareTo(y.toLowerCase());
            }
        });
        Iterator<String> x2=l1.iterator();
        while(x2.hasNext())
        {
            String obj=x2.next();
            System.out.println(obj);
        }
