Learn Java8 Streams By Coding it with Hands on Example

Learn how Java 8 functional interfaces rely on a single abstract method, support default and static methods, and enable lambdas with core interfaces like Consumer, Predicate, Function, and Supplier.

Explore the Java 8 consumer interface with hands-on examples, using lambdas and andThen to chain actions, in an offline person repository demo.

Explore Java 8 streams as a lazy, parallel pipeline for lists, using lambda expressions and intermediate operations to transform and aggregate data without altering the original collection.

Create and manipulate streams from data sources, use Stream.of and arrays, apply forEach, filter with predicates, and collect results into a map of name to Hobbes.

Learn to transform data with streams using map and flatMap to extract hobbies from a list of people, then collect and deduplicate them with distinct.

Compare collections and streams in Java, highlighting read-only streams, lazy evaluation, and one-time use, then demonstrate mapping, peeking, and collecting with practical examples.

Explore the Java 8 streams map operation by transforming a list of fruit names into their lengths, collecting results, and printing them, in a hands-on example.

Transform a list of person objects into uppercase names by retrieving names with getName and applying toUpperCase via stream map, then collect the results with collectors.toList or collectors.toSet.

Demonstrate flat map in Java 8 streams by flattening a list of odd and even integers into a single list, applying a transformation, and collecting into a new stream.

Learn how to use Java 8 streams and flatMap to flatten each person's hobbies into a single list, then collect, deduplicate, and prepare sorted results.

Learn Java streams through a hands-on flatMap example that flattens data, maps, removes duplicates with distinct, sorts results, and counts elements.

Learn how to sort streams in Java 8 using comparator and reversed for name and height, print results, and see how functional programming simplifies custom sorting in this hands-on example.

Master the stream filter in Java 8 by using predicates to restrict data in a list, like names or height, then collect and print the filtered results.

Learn how streams reduce applies a custom accumulation to a list of integers, demonstrated with sum and a multiplication example using a starting value and a BiFunction.

Explore how to use stream reduce to concatenate names with map, and determine the tallest person using a reduce with an initial value, handling optional results.

The lecture demonstrates Java 8 streams using filter, map, and reduce to count each person’s kids by filtering height and gender and summing the results.

Explore java 8 streams using maxBy and minBy to find the tallest and shortest person from a repository, handle optional results, and manage ties with streaming filters.

Learn how to control data flow with stream limit and skip in Java 8, using examples of lists and reduce to print and sum only the desired elements.

Explore how Java streams use allMatch and anyMatch with a predicate to evaluate all elements or any element in a list, demonstrated with height checks and multiple predicates.

Explore how to use streams findAny and findFirst in Java 8, with filters and optionals, to retrieve the first matching element or any matching element efficiently.
