Sachgebiete
The second of two courses that cover the Java Standard Edition 7 (Java SE 7) Platform, this course covers the core Application Programming Interfaces (API) you will use to design object-oriented applications with Java. Learn to create classes that subclass other classes, extend abstract classes, and program with interfaces. Learn how to properly use exceptions, how to use the Collections framework, and develop applications that manipulate files, directories and file systems. This course also covers writing database programs with JDBC, and how to correctly write multi-threaded applications. Use this course to further develop your skills with the Java language and prepare for the Oracle Certified Professional, Java SE 7 Programmer Exam!
Learn To:
- Create Java technology applications with the latest JDK 7 Technology and the NetBeans Integrated Development Environment (IDE)
- Enhance object-oriented thinking skills using design patterns and best practices
- Identify good practices in the use of the language to create robust Java applications
- Manipulate files, directories and file systems
- Write database applications using standard SQL queries through JDBC
- Create high-performance multi-threaded applications
