List<String> list = new ArrayList<String>();
list.add("abc");
list.add("def");
list.add("abc");




HashMap<String, Integer> map = new HashMap<String, Integer>();




for (String str : list) {
Integer c = (Integer) map.get(str);
if (c == null || c == 0) {
map.put(str, 1);
} else {
map.put(str, ++c);
}
}
System.out.println(map);
