Answers for "print hashmaps java"

print map in java

Map<String, Integer> map = new HashMap<>();
map.put("a", 1);
map.put("b", 2);
System.out.println(Arrays.asList(map)); // method 1
System.out.println(Collections.singletonList(map)); // method 2

print only values in map

System.out.println(Arrays.toString(map.entrySet().toArray()));
