Course Description

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 use interfaces including the List interface and how to use Lambda expressions. Additionally, it covers exception handling and deployment of a Java application and how to enhance an application. This course can be used as part of the preparation for the Oracle exam, 1Z0-808, Java SE 8 Programmer, to obtain the Oracle Certified Associate level certification.
