In this video we will learn about one of the Java 8's new features called Stream API. The java stream api introduced in java 8, changed the way we write and read java code.

Java Stream API is an absolute beast when it comes to data processing as it enables the scope to process the data in a declarative approach. It opens a way to fusion multiple methods by doing method chaining and gives us a way to write lambda expressions as most of the Java streams methods accepts lambda as a parameter. Thus we can reduce our traditional loops/condition checks / conversion code and significantly improve our code readability.

As we have discussed, The java Stream api is not a data structure but it is used to process a collection of objects.

In this episode we will learn, How we can open a stream from a source and how we can process the elements from our stream using Stream api methods.

In this video, We will discuss about the
1.Java stream api 's generate() which helps us creating a infinite stream
2. Stream also has a method called Stream.of which helps to create finite data stream
3.We will also understand the way to create java stream from a collection.
4.Last but not the least, we will learn a way to consume each of the elements from a java stream.
