I remember that at this time last year, several engineers from Sun came to our company to give a speech.

There are many standards and practices that can be applied to Java developers. But here we will talk about the basic principles that every Java developer must stick.

Scala is written specifically for the Java™ platform, so its syntax design makes Java code-coding people feel relaxed. At the same time, Scala provides the JVM with the inherent power of functional languages, and starts with these functional design concepts. In this issue of the Scala Guide series for Java developers,
Understanding the basics of Ajax programming is important, but if you're building a complex user interface, it's important to be able to work on a higher level of abstraction. In the 3rd article in the AJAX series for Java developers, I introduced a technique that avoids the tedious details of Java object serialization, based on last month's Ajax data serializati

request package is in a Java 8 completablefutures. WEB3J provides a packaging tool around all asynchronous requests to ensure that any exceptions can be caught during execution, and not just discarded. Because there are many exceptions that are missing support in a full check, these exceptions are usually identified as undetected exceptions, causing problems with the detection process. For more information, see Async.run () and its associated test.

For Java™ developers who learn Scala, objects are a relatively natural, simple entry point. In previous installments of this series, I introduced some of the object-oriented programming methods in Scala, which are actually not very different from Java programming. I also showed you how Scala can reapply the traditional object-oriented concept, find its flaws, and
