Can you explain what is meant by Heap in the context of memory in programming?

Heap is an area of dynamic memory used by a program to store objects and data whose size can change during runtime. In the context of Android and other platforms, the heap is allocated by the operating system and managed by the garbage collector. When an application creates new objects, they are placed in the heap, and memory for them is allocated dynamically.

The heap differs from the stack in that the stack stores local variables and function calls with a fixed lifetime, while the heap contains objects with a more flexible lifetime. Managing the heap is important for preventing memory leaks and optimizing application performance.
