Nothing better than a video course trusted by over 1,70,000 students (yes, that many students). Certified System Configurations; Download and Installation Instructions; Write Your First Application. The rationale for this is to allow for future modularization of the Java SE platform where service providers may be deployed by means other than JAR files and perhaps without the service configuration files. It is compact and easy form of lambda expression. It returns the targeted parallelism level of the common pool. Modularity:One of the biggest changes is the modularity introduced with Java 9. It describes the garbage collectors included with the Java HotSpot VM and helps you to decide which garbage collector can best optimize the performance of your application, especially if it handles large amounts of data (multiple gigabytes), has many threads, and has high transaction rates.
