21.3 Dynamic Memory Allocation
Creating and maintaining dynamic data structures requires dynamic memory allocation—allowing a program to obtain more memory space at execution time to hold new nodes and to release space no longer needed. Remember that Java does not require you to explicitly release dynamically allocated memory. Rather, Java performs automatic garbage collection of objects that are no longer referenced in a program.
The limit for dynamic memory allocation can be as large as the amount of available physical memory in the computer or the amount of available disk space in a virtual-memory system. Often the limits are much smaller, because the computer’s available memory must be shared among many applications.
