Java 8 has been released for some time, and it is considered to be the largest version upgrade since Java 5 was released. The new features provided by Java 8 are mainly focused on Java compilers, class libraries, development tools, and the JVM (Java virtual machines). Lambda expressions, default methods, parallel APIs, and so on, have been sought after by developers, and the community's learning data about Java 8 has sprung up. Here is a summary of some excellent learning materials:

Brian Goetz's answer on Stack Overflow

Brian is one of the authors of Java concurrency programming, with over more than 20 years of experience in software consulting industry. Brian is the lead player in JSR 335, and his team of experts has made a significant contribution to the success of Java 8. Here are some wonderful answers to Brian's questions about Java 8 on Stack Overflow:

• Why can't the "synchronized" keyword in Java 8 be used for interface methods?

• Why is the "final" keyword not allowed for use in interface methods?

• Does the Java concurrency program still work?

• How do I correctly determine if an object is a LAMBDA?

• Why does iterable not provide the stream () and Parallelstream () methods?

• Using semaphore in the parallel stream method in Java 8 could lead to deadlocks, is this a Bug?

• Why is it not allowed to define a method inherited from Java.lang.Object as the default method?

• How do I compare closures (Lambda expressions)?

• Performance comparison of Java 8 serial and parallel streams

• How do I convert iterable to Stream using the Java 8 JDK?
