Java Stream Specializations
As there are primitive data types or specializations like int, long and double. Similarly, streams have IntStream, LongStream, and DoubleStream. These are convenient for making performing transactions with numerical primitives.
1. Specialized Operations
Specialized streams provide additional operations as compared to the standard Stream – which are quite convenient when dealing with numbers.
2. Reduction Operations
Reduce Operation applies a binary operator, it takes a sequence of input elements and combines them to a single summary result. It is all done where first argument to the operator is the return value of the previous application and second argument is the current stream element.
Java 8 Stream Tutorial
Java 8 introduces Stream, which is a new abstract layer, and some new additional packages in Java 8 called java.util.stream. A Stream is a sequence of components that can be processed sequentially. These packages include classes, interfaces, and enum to allow functional-style operations on the elements.
The stream can be used by importing java.util.stream package. Stream API is used to process collections of objects. Streams are designed to be efficient and can support improving your program’s performance by allowing you to avoid unnecessary loops and iterations. Streams can be used for filtering, collecting, printing, and converting from one data structure to another, etc.
This Java 8 Stream Tutorial will cover all the basic to advanced concepts of Java 8 stream like Java 8 filter and collect operations, and real-life examples of Java 8 streams.
