Java8

We use the Java Stream map (an intermediate operation) to map an element in a stream to a different value (of the same or different type).

The Java stream toArray methods, which we learn in this post, allow us to collect/convert a stream into an array.

A PrimitiveIterator in Java is an interface for the primitive specializations of an Iterator. In this post, we will learn about the PrimitiveIterator, its subclasses and its uses.

Collectors mapping in Java is a static method in the Collectors class. In this post, we will learn about the mapping method in Collectors.

In this post, we will learn about the functional interface in Java for functions present as part of the java.util.function namespace.

A Java DoubleStream is a sequence of double-valued elements that supports sequential and parallel aggregate operations.

Many JDK interfaces were enhanced with default methods in Java 8. In this post we will learn about the default methods in the Java Map interface.

Collectors.joining returns a Collector which concatenates the stream elements separated by a delimiter, prefix and suffix in encounter order.

Java 8 StringJoiner class can be used to build a sequence of characters that are separated by a configured delimiter, prefix and a suffix.

Java Streams has a distinct method which removes duplicates by object’s equal method. This post explains ways to apply distinct by a property.
