Module 1 : Introduction to Java, Classes, & Eclipse

Welcome to Java! This first module provides an introduction to the Java language and object-oriented programming. It includes an overview of Java syntax, in particular, how it differs from a language like Python. Topics will include variables and data types, loops and conditionals, printing to the console, scanning for user input, and code documentation. This module also explains the structure and inner-workings of a Java class and teaches you how to define your own custom classes and methods.

Module 2 : Unit Testing, Arrays, & ArrayLists

In this module, you will be taught to test your code to get it working. The best way to do this is to write a set of unit tests that you can run against your program, at any time. In this module, we'll learn how to do unit testing in Java, and why we want to do it. We’ll also learn all about Java Arrays, which are collections of items, and ArrayLists, which are kind of like arrays, but much more flexible. These work just like lists in Python. ArrayLists are part of Java’s larger Collections Framework, which we’ll continue to reference throughout this course.

Module 3 : Static Variables, Methods, & Polymorphism Using Overloading

So far, we’ve been defining variables as instance variables in our Java classes. Instance variables are just variables defined inside a class, and every instance of a class can have a different value for an instance variable.

In this module, we’ll look at defining static variables in our Java classes. Static variables are also defined as variables inside a class, but with the keyword 'static'. Static variables have the same value for every instance of a class. In fact, you don’t even need to create an instance of a class to use a static variable! We’ll also look at static methods. And just like static variables, you don’t need to create an instance of a class to use, or call, a static method. In this module, we’re also going to introduce polymorphism, which refers to overloading and overriding. We’ll focus on overloading, which is having two or more methods in the same class, with the same name.

Meilleurs avis pour INTRODUCTION TO JAVA AND OBJECT-ORIENTED PROGRAMMING

par AL4 avr. 2021

Great course to learn object oriented programming in Java. It was nice that testing was included. Could probably go a little deeper into casting and collections.

par VK11 mai 2021

The course is very good, however it would be really nice to have at least one lecture about Object-Oriented Design in it.

par SA20 mai 2021

It is a great practical introduction course with challenging assignments.

par DA5 avr. 2021

Cool course, a lot of pain through one of the homeworks!

À propos du Spécialisation Introduction to Programming with Python and Java

This Specialization starts out by teaching basic concepts in Python and ramps up to more complex subjects such as object-oriented programming and data structures in Java. By the time learners complete this series of four courses, they will be able to write fully-functional programs in both Python and Java, two of the most well-known and frequently used programming languages in the world today.

Introduction to Programming with Python and Java is for students and professionals who have minimal or no prior programming exposure. It’s for motivated learners who have experience with rigorous coursework, and are looking to gain a competitive edge in advancing their career. It’s for folks who are thinking about applying to the University of Pennsylvania’s online Master of Computer and Information Technology degree and want to sample some of the lecture videos and content from the first course in the program. We hope this Specialization is for you. Topics in this Specialization include language syntax, style, programming techniques, and coding conventions. Learn about best practices and good code design, code testing and test-driven development, code debugging, code and program documentation, and computational thinking.

Foire Aux Questions

Quand aurai-je accès aux vidéos de cours et aux devoirs ?
L’accès à des vidéos de cours et des devoirs dépend de votre type d’inscription. Si vous suivez un cours en mode auditeur libre, vous pourrez voir la plupart des contenus de cours gratuitement. Pour accéder aux devoirs notés et obtenir un certificat, vous devrez acheter une expérience de certificat, pendant ou après avoir assister au cours en tant qu’auditeur libre. Si vous ne visualisez pas l’option auditeur libre :
Il est possible que le cours ne propose pas d’option auditeur libre. Vous pouvez en revanche accéder à un essai gratuit ou faire une demande d'aide financière.
Le cours propose peut-être « Cours complet, aucun certificat » à la place. Cette option vous permet de voir tous les contenus de cours, de soumettre les évaluations requises et d'obtenir une note finale. Cependant, vous ne pourrez pas acheter une expérience de certificat.
À quoi ai-je droit si je m'abonne à cette Spécialisation ?
Lorsque vous vous inscrivez au cours, vous bénéficiez d'un accès à tous les cours de la Spécialisation, et vous obtenez un Certificat lorsque vous avez réussi. Votre Certificat électronique est alors ajouté à votre page Accomplissements. À partir de cette page, vous pouvez imprimer votre Certificat ou l'ajouter à votre profil LinkedIn. Si vous souhaitez seulement lire et visualiser le contenu du cours, vous pouvez accéder gratuitement au cours en tant qu'auditeur libre.
Une aide financière est-elle possible ?
Oui, Coursera offre une Aide Financière aux étudiants qui n'ont pas les moyens d'acquitter les frais. Demandez-la en cliquant sur le lien Aide Financière sous le bouton S'inscrire situé à gauche. Vous devrez remplir un formulaire de demande et vous serez averti(e) si elle est acceptée. Vous devrez répéter cette procédure pour chaque cours de la Spécialisation, y compris pour le Projet Final. En savoir plus.
How much math do I need to know to take this course?
The only math that learners will need for this Specialization is arithmetic and basic concepts in logic.
This course was fun. How can I learn more?
If you enjoyed this course, we recommend Courses 1, 2 and 4 in the series!
If you would like to learn the fundamentals of computer science beyond the basics of programming, consider applying to the Master of Computer and Information and Technology (MCIT) at the University of Pennsylvania, an Ivy League computer science master’s program for people without a computer science background. For an on-campus experience, explore here. If you prefer an online setting, apply to MCIT Online. In fact, the lectures in this series are also used in the online degree program! The Specialization certificate will be viewed favorably by the admissions committee, so be sure to mention it when you apply.
