Java 8 is a giant step forward for the Java language. Writing this book has forced me to learn a lot more about it. In Project Lambda, Java gets a new closure syntax, method-references, and default methods on interfaces. It manages to add many of the features of functional languages wit...
all programming languages support writing sequential code because it's a fundamental concept in programming. however, some languages like c, java, python, and many others, provide features to write both sequential and concurrent or parallel code. what is a sequential circuit in terms of computing?
thread-confined. This enables collection to occur in parallel without the {@code Collector} needing to implement any additional synchronization. The reduction implementation must manage that the input is properly partitioned, that partitions are processed in isolation, and combining happens only after ac...
// The Spliterator API was designed to support efficient parallel traversal // in addition to sequential traversal, by supporting decomposition as well as single-element iteration. // In addition, the protocol for accessing elements via a Spliterator is designed to impose ...
What is the maximum length of a HiLog record? Is it configurable? Why is private displayed in HiLog information when the format parameter %d or %s is specified? What should I do if the hilog.debug log cannot be printed? How do I control the log output level based on the environme...

In multithreading, the application (process) is divided into two or more subprograms (processes), Several such processes originating from a single task, can be simultaneously started and handled by Java, which can be implemented at the same time in parallel. The processor is doing only one ...
Java code formatter improvements IntelliJ IDEA’s code formatter now allows you to retain blank lines between annotations and field declarations, a style that is commonly used in JPA entities to enhance readability. Previously, the formatter removed these lines by default. The new option to control...
