Explore the java.util.function package interfaces, roles of the Predicate, Consumer, Function, and Supplier interfaces, Stream data search approaches, and Optional class methods. Work with Lambda expressions, method references, and Function packages, and other topics covered in this 16-video course. To start, observe how to work with Lambda expressions and method references, then examine java.util.function package interfaces and their roles. Then work with interfaces in the Function package; recognize roles of the Predicate, Consumer, Function, and Supplier interfaces; and use these interfaces based on case studies. Explore Primitive and Binary variations of the Base interfaces of the java.util.function package; extract Stream data by using the map, peek, and flatMap methods; and search stream data with the findFirst, findAny, anyMatch, allMatch, and noneMatch methods. Use Stream API to search and match data; list Optional class methods, and use enhanced features of Optional class in Java SE 11. Perform calculations using the count, max, min, average and sum Stream operation; perform collection sorting using Lambda expressions, and use collectors with Stream, including groupingBy and partitioningBy operations. This is one course is a series to prepare for the 1Z0-816: Java SE 11 Programmer II certification exam.
