Java 8 :: Streams and Lambda Expressions

/*
 * Problem No: #9
 * Problem Definition: How to Print Distinct Element's Count in Integer Array using Stream?
 * 
 * Answer: By Using, 
 * > java.util.Collection.stream(): Returns a sequential Stream with this collection as its source. 
 *  
 *> java.util.stream.Stream.forEach(): Performs an action for each element of this stream.This is a "terminal operation". 
 * 
 * **Same Operations can be applied with LongStream and DoubleStream
