Print HashMap Values with Stream api

Question

HashMap<String, Double> missions = new HashMap<>();
missions.put("name", 1.0);
missions.put("name1", 2.0);
missions.keySet().stream().forEach(el-> System.out.println(el));

This prints only the keys, how do I print the map's values instead?

Solution 1

Use entrySet() (or values() if that's what you need) instead of keySet():

Map<String, Double> missions = new HashMap<>();
missions.put("name", 1.0);
missions.put("name1", 2.0);
missions.entrySet().stream().forEach(e-> System.out.println(e));

Solution 2

HashMap<String, Double> missions = new HashMap<>();
missions.put("name", 1.0);
missions.put("name1", 2.0);
missions.entrySet().forEach(System.out::println);

Output:

name=1.0
name1=2.0
