Question: 1 / 510

For what purpose is the 'allocateDirect()' method used?

To create a buffer that is garbage-collected

To create a buffer with a direct link to the operating system

The 'allocateDirect()' method is used to create a buffer with a direct link to the operating system, bypassing the normal garbage collection process. This allows for more efficient memory management and faster data transfers.

Option A is incorrect because the 'allocateDirect()' method does not create a buffer that is garbage-collected. Instead, it creates a buffer that is directly managed by the operating system.

Option C is incorrect because while the buffer is allocated in virtual memory, the direct link to the operating system is what sets the 'allocateDirect()' method apart.

Option D is incorrect because the 'allocateDirect()' method is not related to locking, which is used for synchronization in multi-threaded applications.
