I am trying to instantiate map in java but I’ve not found a solution for it yet. Can someone share with me your experience?

♦ Suggestions of ITtutoria Team
Idea for “instantiate map in java”: Using a function for initialization will also enable you to generate a map in an initialize. Here is a case study for you:

Map<String, String> myMap = new HashMap<String, String>() {{
 put("a", "b");
 put("c", "d");
 }};

  1. Simplicity, you can do this instruction here

    Map<String, String> emptyMap = Map.of();
Map<String, String> singletonMap = Map.of("key1", "value");
Map<String, String> map = Map.of("key1","value1", "key2", "value2");
