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.
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.
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.
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.
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.
