Java 8: Dumping Content Of a Map

Map<String, String> map = new HashMap<>();
	map.put("java", "42");
	map.forEach((key, value)
			-> System.out.printf("Key: %s Value: %s", key, value)

Output: Key: java Value: 42


Now java is just lacking some nice snytax to create and fill a map.

Like in php where you can do:

myMap = array (
'key1' => 'Value1',
'key2' => 'Value2'

Bad example is it?

Map<String,Object> myMap = new HashMap<>();
myMap.put("key1", "Value1");
myMap.put("key2", "Value2");

1 line less than the example (yeah, nit picking ...). There are things PHP is nicer to work with than java and things where java just shines above PHP.
