Nice Java 7 features

Some upcoming nice new features in Java 7

Underscores in numeric literals : int one_billion = 1_000_000_000; // Comma would have been more natural

Binary Literals : int binary = 0b1001;

Strings in switch statements :
String s = ...
switch(s) {
 case "asinine":
    processAsinine(s);
    break;

  case "foo":
  case "bar":
    processFooOrBar(s);
    break;
    // fall-through

  default:
    processDefault(s);
    break;
}

Not necessary to close resources like InputStream, Writers, Sockets, Sql classes explicitly

This:
BufferedReader br = new BufferedReader(new FileReader(path));
try {
   return br.readLine();
} finally {
   br.close();
}

becomes

try (BufferedReader br = new BufferedReader(new FileReader(path)) { //copied from C# ?
   return br.readLine();
}

Collections ( List,Set and Map)  can be created like in Ruby or Perl. Instead of:

List<String> list = new ArrayList<String>();
list.add("myitem");
String item = list.get(0);

we can do:

List<String> list = ["myitem"];
String item = list[0];
