java 8 examples

With lambda expressions, streams, and a series of small optimizations, Java 8 introduces a new DateTime API, and in the tutorial we'll learn how to use the new API with some simple examples. The way that Java handles dates, calendars, and Times has been criticized by the community, setting Java.util.Date to mutable typ

constant, which means that the value of the Outsideofimpl after it is declared and initialized cannot be changed.This example simply shows how to use a clear lambda expression instead of an anonymous inner class.One tip: JDK8 's release time has been postponed to February 2014, and a complete release schedule can be found here. I update my lambda build project every day, and if any problems arise in the latest build, please feel free to contact me. I will do my best to build on it, and I will p

information about local variable tables, operand stacks, and method exits. Therefore, we can create an infinite recursive call. When the recursive depth is too large, the stack space will be exhausted, resulting in StackOverflowError. The specific code is as follows: /** * @author xiongyongshun * VM Args: java -Xss64k */public class OutOfMemoryErrorTest { public static void main(String[] args) { stackOutOfMemoryError(1); } public static void st
