Новый хэшмап Java
Map<String, String> myMap = new HashMap<String, String>() {{
put("a", "b");
put("c", "d");
}};
Fair Fly
Map<String, String> myMap = new HashMap<String, String>() {{
put("a", "b");
put("c", "d");
}};Map<String, String> emptyMap = Map.of();
Map<String, String> singletonMap = Map.of("key1", "value");
Map<String, String> map = Map.of("key1","value1", "key2", "value2");
// this works for up to 10 elements:
Map<String, String> test1 = Map.of(
"a", "b",
"c", "d"
);
// this works for any number of elements:
import static java.util.Map.entry;
Map<String, String> test2 = Map.ofEntries(
entry("a", "b"),
entry("c", "d")
);
