Five years after Java 6, Oracle has just released Java 7! This is the first release of Java since Oracle bought Sun Microsystems. This new version of Java introduces a lot of new features, but some of the languages new features will be introduced in Java 8 as stated by the “Plan B”. In this [...]
I was presenting the Plan B of JDK 7 the last week and apparently, this plan has been approved. The JDK 7 Features page has been updated on the site of Oracle. So here are the (definitive ?) list of features for JDK 7 : JSR 292: Support for dynamically-typed languages (InvokeDynamic) Languages update of [...]
Mark Reinhold has posted a message about the planning of Java 7. In this message, he explains that the current schedule of the JDK 7 is completely unrealistic. This delay is due to the add of new projects (lambda, Coin, Jigsaw) and the acquisition of Sun by Oracle. The current estimate by the team is [...]
I’ve made another updates to my file copy benchmark. First of all, I used my little utility class to automatically create the graphs. The graph are a little less clean, but I spare a lot of time not creating them myself. Then, I’ve also made some corrections on the code : I”ve used a buffer [...]

At this time, we aren’t sure that the closures will be included in the Java 7 release. But these doubts have generated a new project : The “public defender methods” proposal. This new proposal for Java 7 wants to improve the interfaces allowing to add new methods to existing interfaces. The classes implementing the interfaces [...]
2 days ago, Oracle pushed a first version of the closures implementation. We can see the evolving syntax in the test cases they made for the Java compiler. You can see these test cases here. This revision supports the following features (copied from revision) : Function types syntax Function types subtyping Full support for lambda [...]
