Java8

A Function is primarily used along with the map operation on a Java stream. In this post, we will learn about Function chaining in Java 8.

We have used a Predicate in a Java stream. This post covers the methods in Predicate class which allow us to do Predicate chaining in Java 8.

Java 8 added three Summary Statistics classes viz., IntSummaryStatistics LongSummaryStatistics and DoubleSummaryStatistics used to collect statistics.

This post covers the default method resolution rules. These will be used when a class inherits more than one method with the same signature.

Optional is a container object added to Java 8+ that is used as a wrapper over some value. It provides a mechanism to represent “no result” for a method.

A method reference is a reference to an existing method. When a lambda expression just calls an existing method, we can use a Method Reference.

A sequence of primitive int-valued elements supporting sequential and parallel and aggregate operations. It is an int primitive specialization of Stream.

The Comparator is a comparison function in Java that imposes a total ordering on a collection of objects. The comparing is a static method in it
