Java 7 New Features

Try that autocloses of resources
=================================
try (
   InputStream in = new FileInputStream(src);
   OutputStream out = new FileOutputStream(dest))
{
 // code
}


Shorter and more concise Type deifnitions in generics
=====================================================
Before: 
	Map<String, List<String>> anagrams =
			new HashMap<String, List<String>>();
Now:
Map<String, List<String>> anagrams = new HashMap<>();


String in case statement
========================

String s = "foo";
switch(s) {
 case "quux":
    processQuux(s);
    // fall-through

  case "foo":
  case "bar":
    processFooOrBar(s);
    break;
}


Multiple exception catching
============================
 Before: 
 } catch (FirstException ex) {
     logger.error(ex);
     throw ex;
} catch (SecondException ex) {
     logger.error(ex);
     throw ex;
}
Now:
try{
	// Some code
} catch (FirstException | SecondException ex) {
     logger.error(ex);
    throw ex;
}

SafeVarargs
===========
Before:
@SuppressWarnings({"unchecked", "varargs"})
	public static void printAll(List<String>... lists){
	    for(List<String> list : lists){
	        System.out.println(list);
	    }
	}
Now:
@SafeVarargs
public static void printAll(List<String>... lists){
    for(List<String> list : lists){
        System.out.println(list);
    }
}
