课程 2（共 4 门，Specialization Object Oriented Programming in Java）

This course will build on the skills you learn in Java Programming: Solving Problems with Software. You will continue to expand your programming skill set to read and manipulate data with more complex structure. You will also write programs with more complex structure. By the end of this course, you will be able to: 1. Read and write data from/to files; 2. Solve problems involving data files; 3. Perform quantitative analyses of data (e.g., finding maximums, minimums, averages); 4. Store and manipulate data in an array or ArrayList; 5. Combine multiple classes to solve larger problems; 6. Use iterables and collections (including maps) in Java.

Welcome

Welcome to “Java Programming: Arrays, Lists, and Structured Data”! We are excited that you are starting our course to learn how to write programs in Java, one of the most popular programming languages in the world. In this introductory module, you will hear an overview of this course and be introduced to the supporting resources available.

>> Hi, I'm Susan and

I'm really excited to be working with our team at Duke to introduce this course.

Java Programming, Arrays, Lists, and Structured Data.

We've designed a great set of problems and programs that combine real world data

analytics with lessons that introduce security and cryptography.

Whether this is your first course with our great team, or

you're coming from our previous courses as part of Java programming and

introduction to software specialization.

You'll use a seven-step process to help you design and

implement Java programs to solve problems and

hone the skills that will help you become an effective software engineer.

In working on the problems we've designed, you'll learn about arrays and

maps, two standard data structures that are used to create efficient and

robust programs to solve problems.

As part of our cryptography lesson, you'll learn how the words melon and

cubed are related by the number 16.

>> Hello, I'm Drew.

In this course, you'll be using the edu.duke library of classes we've designed

to write programs that solve interesting problems, like analyzing web logs, and

generating random stories from templates.

But you'll also use the standard java.util library of classes that will help you grow

your knowledge and skill in using java to create solutions to these problems.

Understanding APIs so you can use code from libraries is an important part of

this course, as is beginning to develop an understanding of object-oriented program.

In this course, you'll learn how classes are structured and

how programs are created by strategically combining classes together.

You'll also learn about how the words fusion and

layout are related by the number 20.

>> Hi, I'm Robert.

For this course,

we've designed an exciting mini-project as part of this course to help you learn

more about classes, object-orientation, and data structures.

You will use standard techniques and libraries that are part of nearly

all java programs designed to solve problems at scale.

We've structured the module in this course to introduce topics, and

then explore them in more detail, and with more robust,

scalable solutions that improve upon that initial program.

This allows you to learn the new techniques while solving

a familiar problem.

We hope that this learning approach will facilitate success for all learners.

Also in this course, you'll learn how the number 19 connects to words,

jolly and cheer.

>> Hi, I'm Owen.

I'm excited about the approach we've taken in this course

to introduce two important programming structures, arrays and maps.

These are not simply Java structures.

They are used in every programming language to create efficient solutions

to programming problems.

By exploring how these structures are related and encountering them in familiar

contexts, you'll be able to practice using them as you develop mastery with

both concepts and the Java libraries that anchor these concepts in code.

You'll also learn why having 14 fake toys

would be an enormous cryptographic coincidence.

Welcome to arrays, lists and structured data.
