Course Summary

This course will teach students about Java 7 with its new language improvements such as support for type inference and improved exception handling. It will also include the new features in this release such as the ability to work with symbolic links, a greatly simplified directory traversal technique, the monitoring of file creation and deletion, event handling, security, and concurrent processing. Students will also learn about the new NIO techniques that provide enhanced capabilities which are complemented by the try-with-resources block and the enhanced generic support. Also covered is the new JLayer decorator and improved window methods which will enhance the developer?s ability to create GUI applications.
