Problem No: #2 How to Sort and Print List of Collection type Using Stream?

Java 8 :: Streams and Lambda Expressions

/*
 * Problem No: #2
 * Problem Definition: How to Sort and Print List of Collection type Using Stream?
 * 
 * Answer: By Using, 
*>java.util.Collection.stream(): Returns a sequential Stream with this collection as its source. 
 * >java.util.stream.Stream.sorted(): Returns a stream consisting of the elements of this stream, sorted according to natural order.This is a stateful intermediate operation.
 * >java.util.stream.Stream.forEach(): Performs an action for each element of this stream.This is a terminal operation. 
 * 
 * NOTE : In Case of Using java.util.stream.Stream.sorted() method for ordered streams, the sort is stable. For unordered streams, no stability guarantees are made.
