The non-Java JVM languages tend to be more concise (less verbose) than Java. Almiray showed the common JavaBean example written in Java and said we have come to rely on IDEs because of the pain ...

James Ward is a Java Champion and Google’s Kotlin product manager. In this interview, he speaks about the state of Java, JVM languages, mutability, and functional programming.

The main thing that makes Ratpack interesting is the execution model, which aims to make asynchronous programming on the JVM easier.

Enter Scala: a statically-typed language that compiles to the Java Virtual Machine (JVM) and is a blend of object-oriented and functional programming paradigms.

The Java virtual machine (JVM) is a program whose sole purpose is to execute other programs. This simple idea has made Java one of the most successful and long-lived platforms of all time.

For both short- and long-term allocations, the C++ program is considerably faster than the Java program running on any JVM. Short-term allocations have been one focus area for optimization in HotSpot.

Much of its popularity is due to JVM compatibility and support for Java 6; but more importantly, it's possible to build a project with a mix of code files written in either Kotlin or Java.
