var str = "Java 10"; // infers String 
var list = new ArrayList<String>(); // infers ArrayList<String> 
var stream = list.stream(); // infers Stream<String>

3)Application class Data sharing : Now in Java 10 , we can share application classes as well , so what is class data sharing is , actually there is a shared class in JRE where JRE dump its file called shared archive, which is used to load the library of JRE. Now in Java 10 we can added the Application class as well in shared class.
