Iterate a Map in order of second operator (integer) [JAVA]

Question

Map<String,Integer> map;
map.put("hey",1); 
map.put("k",0); 
map.put("thanks",12);

How can I iterate the map entries in order of the second operator (the numbers)? thanks

I meant: Map (left operator is a String and the right is Integer) — rhia, Dec 26 '15 at 11:13
LinkedHashMap but it didn't work because I do not put the items in order — rhia, Dec 26 '15 at 11:15

    Map<String, Integer> map = new HashMap<>();
    map.put("hey",1); map.put("k",0); map.put("thanks",12);
    map.entrySet().stream()
        .sorted((x, y) -> x.getValue() - y.getValue())
        .forEach(System.out::println);

resullt:

k=0
hey=1
thanks=12
