Core Java Refcard: My second dzone refcard has been published. This refcard gives you an overview of key aspects of the Java language and cheat sheets on the core library (formatted output, collections, regular expressions, logging, properties) as well as the most commonly used tools (javac, java, jar).
Features include Java Keywords, Standard Java Packages, Character Escape Sequences, Collections and Common Algorithms, Regular Expressions, JAR Files and more. Posted by cayhorstmann at (21:06 PST) | Permalink | Discuss (0)
