Java Functional programming with lambda and streams

Learn how to define a functional interface in Java 8, implement its single abstract method via class, anonymous inner class, and lambda expressions, with a runnable car example like BMW.

Learn the syntax of Java lambda expressions, pass arguments, and return types, with practical examples, including a run method with distance and a bank balance calculation.

discover how lambda expressions capture outer variables only when final or effectively final, and how lazy evaluation defers execution, evidenced by a vehicle distance example.

Explore Java functional programming by using consumer to process inputs and supplier to produce and return values through lambda expressions, including chaining and the get method for random UUID outputs.

Explore function, predicate, and unary operator in Java functional programming. Learn how a function maps an input to an output, and how predicates filter streams with booleans.

Explore Java eight functional interfaces BiFunction, BiConsumer, BiPredicate, and BinaryOperator, and learn to combine two inputs into an output using apply, accept, and test.

Learn to use method references in Java to reference static methods and constructors, and apply them with consumer, supplier, and function interfaces in lambda workflows.

Explore Java streams from the Java util stream package to transform, filter, map, reduce, and collect data with lambda-based functional operations, enabled by lazy evaluation and parallel processing.

Demonstrates creating a simple hello world stream from a list, showing internal iteration via stream forEach and a lambda consumer, instead of a traditional external for loop.

Learn to create streams from arrays, collections, builders, iterators, and generators. Apply operations like filter, map, distinct, and sorted, then perform terminal actions such as collect and reduce.

Explore how to create streams in Java using arrays, collections, stream.of, stream builder, iterate, and generate, with examples and terminal operations.

Shows that streams compute without mutating the original collection, producing new collections via intermediate operations. Executes only at terminal operations, illustrating lazy evaluation and collect toList returning filtered results.

Explore hands-on stream operations in Java functional programming with lambda and streams, creating streams from a collection, applying filter, map, limit, skip, and terminal operations.
