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...
面向JVM 开发者的全新交互式环境 Kotlin Notebook 现已成为 IntelliJ IDEA 的内置功能! Kotlin notebooks are perfect for a wide range of tasks – from real-time prototyping, presenting, log parsing, and documentation writing to in-depth data analysis and visualization. ...

Classes in the newjava.util.streampackage provide a Stream API to support functional-style operations on streams of elements. The Stream API is integrated into the Collections API, which enables bulk operations on collections, such as sequential or parallel map-reduce transformations. ...
Hadoop Streaming uses UNIX standard streams as the interface between Hadoop and your program so you can write MapReduce program in any language which can write to standard output and read standard input. Hadoop offers a lot of methods to help non-Java development. The primary mechanisms are Hado...
The try-with-resources statement, introduced in Java 7, is a valuable addition to exception handling. This construct serves as a try statement that declares and manages one or more resources, particularly addressing the challenge of correctly handling resources like SQL connections or streams, which...
In languages such as C#, VB.Net, C++, Java etc., the stream metaphor is used for many things. There are file streams, in which you open a file and can read from the stream or write to it continuously; There are network streams where reading from and writing to the stream reads from...
So in a sense, the default method was critical to support the development of bulk data operations with a lambda expression. If you want to learn more about bulk data operation and Stream API, I suggest you go through the Java Streams API Developer Guide on Udemy, one of the hands-on cou...
The key classes involved in socket programming in Java are the Socket and ServerSocket classes. The Socket class represents a client-side socket that allows the client application to connect to a server. The ServerSocket class, on the other hand, represents a server-side socket that listens...
Possibly unbounded. Collections have a finite size, but streams don’t. Short-circuiting operations such as limit(n) or findFirst() can allow computations on infinite streams to complete in finite time. Consumable. During the lifetime of a stream, the elements of the stream are only visited ...
