Java SE: Inheritance, Interfaces, and Collections

This course introduces the Java programming language and how to develop Java applications using Eclipse. Students learn the syntax of the Java programming language, object-oriented programming using Java, exception handling, generics, collections, and file input/output (I/O). With a focus on many of the common programming Java commands like Arrays, and Inheritance. Then you will move on how to deal with Exceptions. Then off to Polymorphism, Collections, generics and other useful Java classes.
