This course is your detailed guide to the fundamentals of the Java programming language. This course will get you on the fast track to becoming a proficient and modern Java developer.

In this course, you will start by covering different programming paradigms like object-oriented and procedural programming. You will then cover the fundamentals of programming in Java such as: objects and data types, variables, arrays, and conditional statements.

In the latter half of the course, you will cover iterative constructs, useful algorithms, and data structures. With over 100 problems, 11 quizzes, and 9 challenges, this course will get you prepared for a career in software development.

A Complete Guide to Java Programming

A class is not a good example of abstraction. We need an Interface for that.

A class is not a good example of abstraction. We need an Interface for that.

We cannot implement multiple interfaces.

By default, the interface methods are `public` and `abstract`.

By default, the interface methods are <code>public</code> and <code>abstract</code>.

Evaluate yourself with a quiz on the concepts of interfaces and abstraction that you have studied in this chapter.
