Podrobnosti:
The Java SE 7 Fundamentals course was designed to enable students
with little or no programming experience to begin to learn programming
using the Java programming language. The course teaches the significance
of object-oriented programming, the keywords and constructs of the Java
programming language, and the steps required to create simple Java
technology programs. Students taking this course can receive a solid
basis in the Java programming language upon which to base continued work
and training. The course features the Java Platform, Standard Edition 7
(Java SE 7), and uses the Java SE Development Kit 7 (JDK 7) product.
Students taking this course will have hands on experience learning
basic object oriented concepts such as inheritance, encapsulation, and
abstraction. They learn how to create and use simple Java classes
containing arrays, loops, and conditional constructs. They also learn
to use and manipulate object references, and to write simple error
handling code. The course provides a solid understanding of what the
Java SE7 platform is and how it is used in real world applications.

- Use various Java programming language constructs to create several Java technology applications
- Use decision and looping constructs and methods to dictate program flow
- Perform basic error handling for your Java technology programs
