What additional tasks does the garbage collector perform besides freeing memory from unused objects?

In addition to freeing memory from unused objects, the garbage collector in Java performs the following tasks:

• Optimizing memory allocation, such as moving live objects to reduce fragmentation.
• Managing object generations (Young Generation, Old Generation), which helps improve cleanup efficiency.
• Finalizing objects if they have a finalize() method before deletion.
• Monitoring and collecting statistics about memory usage to optimize application performance.

Thus, the garbage collector not only frees memory but also maintains efficient resource management of the JVM.
