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

Section 1.16 Summary

  • 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.
