Java 是一款跨平台的软件设计语言，Oracle Java 7 为一些程序使用提供环境需求，甲骨文公司发布了 Java 7 Update 40 (7u40) ，WebUpd8 Java PPA 也被更新，大家可以方便的安装 Oracle Java 7 Update 40 (7u40)，支持 ubuntu 和 debian 用户。

Oracle Java 7u40 引入了以下新的特点：

• Part of JMC, Java Flight Recorder enables you to record events and metrics during runtime and extract them at will;
• support for the Retina display with Swing/AWT and JavaFX;
• new JDK binary for hardfloat Linux/ARM, for ARM-based micro servers and development boards. With this, JDK 7 now officially supports the Rasbian Linux distribution (for Raspberry Pi);
• a new Deployment Rule Set feature to enable fine granular controls for execution of Applet and WebStart applications;
• security feature enhancements for applets, JAXP and x.509 certificates.
