How to open files in Java (AP CSA 2026)
How to open a file in Java is a new topic for AP CSA in 2026. So this video explains how to read files in Java using Java's Scanner class for students or teachers in AP CSA. By understanding Java file I/O, you'll get higher scores and be able to solve questions more easily on the AP Computer Science A exam.
We'll learn about Scanner and IOException by working through two examples, the first using Java's Scanner.next and Scanner.nextInt methods to process a file, and the second using Scanner.nextLine() and String.split().
