About the Course

Introduction to Java

  • Grade 9+
  • CTY-Level
  • Individually Paced

Learn the basic features of the Java programming language such as primitive and non-primitive data types, control flow constructs, built-in class libraries, and object-oriented programming concepts like classes, objects, method overloading, and encapsulation. Your typical assignments and projects will include using built-in and programmer-defined classes, performing basic input and output operations, and solving more complex programming problems with a real-world focus. At the end of this course, you’ll submit a comprehensive final examination and will be prepared to study more advanced topics in our next-level course, Advanced Java Programming.

Students may enroll in this course at any time during the year.
