A DESCRIPTION OF THE PROBLEM :
Autoboxing Overhead: When working with primitive types (int, long, etc.), Java converts them into objects (Integer, Long), which slows down processing and increases memory usage.
Inefficient Parallel Processing: Task splitting in parallel streams can lead to uneven workloads, meaning the stream may not fully utilize all CPU cores.
Memory Consumption: Intermediate objects created during filtering add extra overhead, especially when filtering large collections.
