What is achieved with data encapsulation in Java?

Data is compressed to save space
Sensitive data is encrypted automatically
Data and the code that manipulates it are bundled together
Multiple copies of the same data are stored to prevent data loss

The correct answer is: Data and the code that manipulates it are bundled together

Data encapsulation in Java is the process of bundling code and data together into a single unit. This offers many benefits such as data hiding, improved security, and improved maintainability. Option A is incorrect because data encapsulation does not involve compressing data to save space. Option B is incorrect because while data encryption can be a feature of data encapsulation, it is not the main purpose. Option D is incorrect because data encapsulation does not involve storing multiple copies of the same data.
