This trail covers the fundamentals of programming
in the Java programming language.
Object-Oriented Programming Concepts
teaches you the core concepts behind object-oriented programming:
objects, messages, classes, and inheritance.
This lesson ends by showing you how these concepts
translate into code.
Feel free to skip this lesson
if you are already familiar with object-oriented programming.
Language Basics
describes the traditional features of the language,
including variables, data types, operators, and control flow.
Object Basics and Simple Data Objects
shows you the general principles for creating
and using objects of any type.
Then, this lesson describes how to use
arrays, strings, and number objects,
which are commonly used object types.
Finally, this lesson shows you how
to format data for output.
Classes and Inheritance
describes how to write the classes from which objects are created.
Interfaces and Packages
are features of the Java programming language
that help you to organize and structure your classes
and their relationships to one another.
Common Problems (and Their Solutions)
explains the solutions to some problems
you might run into while learning the Java language.
