Podrobnosti:

The Java Programming Language course provides students with a solid foundation for programming with Java, including the syntax of the Java(TM) programming language; object-oriented programming with the Java programming language; creating graphical user interfaces (GUIs), exceptions, file input/output (I/O), and threads; and networking. Programmers familiar with object-oriented concepts can learn how to develop Java technology applications. The course uses the Java 2 Software Development Kit, Standard Edition (J2SE[TM] SDK), version 5.0. The students perform the course lab exercises using the NetBeans Integrated Development Environment (IDE). Students who can benefit from this course:Programmers who are interested in adding the Java programming language to their list of skills* Students who are preparing for the Oracle Certified Professional, Java SE 5 Programmer examination
