Course FAQ
Course FAQ
What will I learn in this Java course?

In this course, you will build a solid understanding about Java collections and be able to pick the right data structure for your data needs and solutions. You will be able to understand the performance implications of each of the different collection types and be able to study and pass the collections portion of the Java Developer Certification.

Are there prerequisites for this course?

Before starting this course, you should be up to date on the Java Developer Certification Path with a solid understanding on the material covered up to this point.

What is a Java array?

An array in Java is a container object that holds a fixed number of values of a single type. The length of an array is fixed and established when the array is created.

What are Java generics?

Java generics are sets of related methods or sets of similar types. Generics allow different data types: integers, strings, or other user-defined types to be used as a parameter to classes, methods, or interfaces.

What are the benefits of Java collections?

Collections reduce required programming efforts by providing useful data structures and algorithms. The collections framework frees you to concentrate on important parts of your program rather than low level maintenance required to make it work.

Course Overview
Do you want to understand Java collections and the Java array data types better? Are you looking to study and pass the Java Developer certification exam? If so, then you have found the right course to help you with those goals. Arrays and collections are a foundational type to any language, and Java is no exception. Hello, everyone. My name is Dan Bunker, and welcome to my course on arrays, collections, and generics in Java. With a solid understanding of collections, you can pick the right data structure for your coding needs and solutions, understand the performance implications of each of the different collection types, and prepare to study and pass the collections portion of the Java Developer certification. By the end of this course, you'll be able to instantiate and use most of the common Java collection types. You'll also be more comfortable looking at and analyzing code snippets that use arrays, collections, and generics. To get the most out of this course, you should follow the Java Developer certification course path that Pluralsight has set up. This path will help you learn the proper Java concepts in the correct order, as well as help you pass the examination. Get ready to learn and to practice some code samples on your own and to internalize the Java concepts discussed in this course. With that, let's go ahead and get started.
