Complete Java SE 8 Developer Bootcamp - Encapsulation and Data Hiding

The video tutorial explains the concepts of encapsulation and data hiding in object-oriented programming. Encapsulation involves bundling data with methods, while data hiding restricts direct access to object data. Access modifiers like public and private control data visibility. The MyDate class example illustrates how encapsulation improves program quality by preventing invalid data manipulation. The tutorial also highlights issues with direct data access and discusses memory efficiency and flexibility in data types.
