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.

TOP REVIEWS FROM INTRODUCTION TO JAVA AND OBJECT-ORIENTED PROGRAMMING

by VKMay 11, 2021

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

by TDMay 28, 2022

A 10 out of 10 course. Very well designed and the assignments are great for enhancing learning and understanding.

by BDDec 11, 2022

Great Lectures from Brandon. Very clear and easy to follow along. I look forward to taking future classes led by him!

About the Introduction to Programming with Python and Java Specialization

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.

Frequently Asked Questions

When will I have access to the lectures and assignments?
Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
What will I get if I subscribe to this Specialization?
When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.
Is financial aid available?
Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
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.
