Better Map Constructor

Question

Is there a more streamlined way to do the following?

Map map = new HashMap();
map.put(\"a\", \"apple\");
map.put(         


        

Answer 1

You could always use double brace initialization:

Map map = new HashMap() {{
    put("foo", "bar");
    put("baz", "qux");
}}

But bear in mind this might not be efficient according to these answers.
