Problem Solving with Algorithms and Data Structures using Java The Interactive Edition

Computer science is the study of problem solving.

Computer science uses abstraction as a tool for representing both processes and data.

Abstract data types allow programmers to manage the complexity of a problem domain by hiding the details of the data.

Java is a powerful object-oriented language.

Arrays and ArrayLists are Java sequential collections.

HashMaps and Sets are nonsequential collections of data.

Classes allow programmers to implement abstract data types.

Programmers can override standard methods as well as create new methods.

Programmers can have multiple methods with the same name as long as their number and/or types of parameters differ. This is called overloading a method.
