What is the primary goal of garbage collection in Java?

To speed up program execution
To enforce access control on object data
To automatically manage memory usage
To compile Java code into machine language

The correct answer is: To automatically manage memory usage

The primary goal of garbage collection in Java is to automatically manage memory usage. This is because Java is an object-oriented programming language and objects are created and stored in memory during program execution. If these objects are not properly managed and removed when they are no longer needed, it can lead to memory leaks and inefficient use of memory. This is why garbage collection is important in Java to automatically remove unused objects and free up memory for other processes. The other options are incorrect because enforcing access control on object data and compiling Java code into machine language are not the primary purposes of garbage collection. While garbage collection can have some impact on program execution speed, its primary goal is memory management and not optimization for speed.
