Java SE 8 Fundamentals: Data Manipulation and Inheritance

Beginners to programming who have basic mathematical, logical, and analytical problem-solving skills and who want to begin learning the Java programming language; novice programmers and those programmers who prefer to start learning the Java programming language at an introductory level; and students who want to begin their study of the Oracle Certified Java Associate exam |

Prerequisite
None

Expected Duration
130 minutes

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 the NetBeans debugger. It covers working with dates, and processing the args array and two-dimensional arrays as well as using the ArrayList class. It also covers inheritance in Java classes, including superclasses, subclasses and abstract classes. 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.
