Stream Builder

The Stream Builder interface makes it really easy to create an instance of Stream with ease. Have a look at the following example:

  fun main(args: Array<String>) { 
      val stream = Stream.builder<String>() 
              .add("Item 1") 
              .add("Item 2") 
              .add("Item 3") 
              .add("Item 4") 
              .add("Item 5") 
              .add("Item 6") 
              .add("Item 7") 
              .add("Item 8") 
              .add("Item 9") 
              .add("Item 10") 
              .build() 
      println("The Stream is ${stream.collect(Collectors.toList())}") 
  } 

The output is as follows:

The Stream.builder() method returns an instance of Streams.Builder. Then, we used the Builder.add function; the add function accepts an item for the stream value to be built, and ...
