sBooksProjectionMap = new HashMap<String, String>();

Could anyone explain to me the meaning of this part of of above code:

new HashMap<String, String>()

I'm a newbie for Java and the <Sting, String> part is confusing me.

`HashMap()` it says that HashMap key and value will be of `String` type — exexzian, Jan 27 '13 at 14:21

Upvoted. If you don't know the keyword 'generic' it's damn hard to search for it. This is a newbie question, not a dumb question. — Croo, Jan 27 '13 at 14:36

Simply-

Map< key, value > map = new HashMap< key, value >();

example would be

Map<String,String> map = new HashMap<String,String>();
map.put("str","abcd");
map.put("str1","dcba");

Now getting them simply

map.get("str");  // abcd
map.get("str1"); // dcba
