Java, an object-oriented programming language, is one of the most widely used development languages in the world today. It allows programmers to create objects that can interact with other objects to solve a problem. This course covers how to implement parallelism with the Fork-Join framework and it covers using parallel streams. It explores the layout of the Java database connectivity application program interface or JDBC API, as well as connecting to a database by using a JDBC driver, submitting queries and getting results from the database, specifying JDBC driver information externally, and using transactions with JDBC. The advantages of localizing an application, defining locales, building a resource bundle for each locale, calling a resource bundle from an application, changing the locale for a resource bundle, and formatting text for localization by using NumberFormat and DateFormat are also covered. This course can be used to as part of preparation for the Oracle Certified Professional, Java SE 8 Programmer II exam.
