Java: Data Types, Operators, and Decision Constructors is the first course of Exam Prep: Oracle Certified Associate, Java SE 8 [1Z0-808] Specialization. This course begins with Java fundamentals, guiding learners through class structures, variable scope, and the lifecycle of Java objects. The module also introduces the difference between primitive and reference data types, how to read and write object fields, and how to work with wrapper classes for data conversion and autoboxing. Through practical examples, students learn to evaluate expressions, test equality using == and .equals(), and build decision structures using if, if-else, ternary (?:), and switch statements.

There are 3 modules in this course
Welcome to Week 1. We will start by exploring how variables work in Java, including how to define their scope and manage data safely and efficiently. Next, we’ll dive into the structure of a Java class, understanding how its components, fields, methods, and access modifiers, come together to form a cohesive program. You’ll then learn how to write and execute your first Java application using the main() method, the entry point for all standalone Java programs. We’ll also cover how to import other Java packages to extend functionality and make your code more modular and maintainable. By the end of this module, you’ll be confident in writing simple, executable Java programs, organizing code effectively into classes, and leveraging Java’s core language features to build well-structured applications.

Welcome to Week 2. This week, we’ll explore how Java manages data and objects. We’ll begin by learning how to declare and initialize variables, understanding how memory is allocated and how different data types behave. You’ll then differentiate between primitive types and object references, gaining insight into how Java handles data storage, manipulation, and assignment. Next, we’ll move into the world of object-oriented programming, where you’ll learn to access and modify object fields and examine the object lifecycle, from creation to garbage collection. You’ll also develop code that uses wrapper classes, bridging primitive data with Java’s object features to support collections and utility operations. By the end of this module, you’ll be able to confidently define, manipulate, and manage data in Java programs while applying best practices in object-oriented design and variable management, setting a strong foundation for advanced topics in Java programming.

Welcome to Week 3 on Java’s core decision-making and operational constructs. This week, you’ll explore how Java handles expressions, operator precedence, and logical evaluation to form the foundation of program control flow. You’ll start by learning how to correctly apply Java operators and use parentheses to override default operator precedence for predictable outcomes. Next, we’ll focus on decision constructs, writing conditional logic using if, if/else, and ternary expressions to handle complex branching in your code. You’ll also gain hands-on experience creating switch statements for more efficient multi-case decision control. Finally, you’ll wrap up by comparing and contrasting the key features and components of the Java language, reinforcing your understanding of how these constructs interact within a Java program. By the end of this module, you’ll be able to design clear, efficient, and logically sound Java programs that make precise decisions based on dynamic conditions.

Frequently asked questions
To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. 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.
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.
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.
