Examples of using Java 8 features To illustrate how these Java 8 features work in practice, let's dive into some real-world Java 8 code examples. We'll explore scenarios where lambda expressions, method references, streams, and the Date and Time API can be applied to solve common programmin...
That’s it for the streams overview. In the next article we’ll look a bit more at lambda expressions. This entry was posted in CodeProject, Java 8 Functional Programming with Lambda Expressions and tagged ForkJoin, Functional Programming, iterator, Java 8 Functional Programming, parallel, Recurs...
A common (bad) practice is to return the null reference to indicate the absence of a sound card. Unfortunately, this means the call togetUSB()will try to return the USB port of a null reference, which will result in aNullPointerExceptionat runtime and stop your program from running furth...

Adoption rate is a good proxy for the quality of an IDE, but with one hitch: increasingly, Java developers are using multiple IDEs to meet the needs of their Java development practices. In fact, 42% of respondents say they use more than one Java IDE in their Java development practice. Am...
this example, as with the object stream in the Event example, the namespace prefix is added to both the opening and closing HTML tags. Adding this prefix is not required by the StAX specification, but it is good practice when the final scope of the output stream is not definitively known...

注意:Java 8引入的CompletableFuture与(并行执行的)Stream底层是通过ForkJoinPool来执行,所以支持ForkJoinPool后,TTL也就透明支持了CompletableFuture与Stream。🎉 java.util.TimerTask的子类(对应的执行器组件是java.util.Timer) 修饰实现代码在TimerTaskTtlTransformlet.java。从版本2.7.0开始支持。
