The Eclipse Foundation has released GlassFish 7.0.21, an update of the enterprise Java application server that focuses on fixing a few tenacious bugs. The release also brings improved connection pool lookup messages and improved error messages on deploying apps larger than the upload size limit in Admin Console. Downloadable from glassfish.org, GlassFish 7.0.21 was introduced…
Java would finally shed its Java Applet API under an OpenJDK proposal created December 4. The JDK Enhancement Proposal notes that the API not only has been deprecated for removal for some time but is obsolete, because neither the current Java Development Kit (JDK) nor current web browsers support applets. Removal is slated for the…
The ability to perform multiple operations simultaneously is one of the most important aspects of any programming language. Orchestrating multiple paths of execution is inherently complex and there are various approaches to taming this complexity. Kotlin is a JVM language growing in popularity for its clean union of functional and object-oriented paradigms. In my previous article, I…
Generics in Java enhance the type safety of your code and make it easier to read. In my last article, I introduced the general concepts of generics and showed examples from the Java Collections Framework. You also learned how to use generics to avoid runtime errors like the ClassCastException. This article goes into more advanced…
After Java, Kotlin is the most popular JVM language. Kotlin is an expressive, concise language with strong functional programming support. It’s especially appealing to Java developers because it is fully interoperable with Java, and the syntax is an easy transition. Let’s take a look at this dynamic programming language. Get started with Kotlin Kotlin is a great…
Java’s internal systems and syntax are constantly evolving, and these changes happen primarily through the Java Community Process (JCP) and Java Enhancement Proposals (JEPs). Together, the JCP and JEPs define the path by which new features can be described, designed, and—hopefully—introduced into the JVM. They keep the Java language and platform dynamic and the community…
Generics are used in Java to allow types or methods to operate on objects of various types while providing compile-time type safety. Generics address the problem of ClassCastExceptions being thrown at runtime as a result of code that is not type safe. In this Java 101: Learn Java article, I introduce you to generics and…
Oracle is touting a “tip and tail” model for Java library development that the company says would give application developers a better experience and at the same time help library developers innovate faster. The JEP (JDK Enhancement Proposal) created September 30 and updated October 7 describes a release model for software libraries. The “tip” release…
Java Development Kit (JDK) 23 having arrived September 17, work already has begun on JDK 24, with two features so far proposed for the release: warnings to prepare developers for future restrictions on the use of JNI (Java Native Interface) and a late barrier expansion for the G1 garbage collector. A multitude of other features,…
Introduced in Java 5, generics enhance the type safety of your code and make it easier to read. This helps you avoid runtime errors like the ClassCastException, which happens when you try to cast objects to incompatible types. In this tutorial, you’ll learn about generics and see three examples of using them with the Java…
