Learn how to create objects, test and modify their class and instance variables, call an object’s methods, and convert objects from one class to another.

Java is an object-oriented programming language. When you do work in Java, you primarily use objects to get the job done. You create objects, modify them, change their variables, call their methods, and combine them with other objects. You develop classes, create objects out of those classes, and use them with other classes and objects.

In this course, you work extensively with objects as you undertake these essential tasks:

  • Creating objects
  • Testing and modifying their class and instance variables
  • Calling an object’s methods
  • Converting objects from one class to another
