Essentials

Essentials is a lightweight collection of high-performance utility classes designed to enhance standard Java and Android development without introducing heavy dependencies. The library focuses on providing efficient data structures and helper utilities that often outperform equivalent components in the standard Java API. It is intentionally minimalistic and is not positioned as a full framework, but rather as a focused toolkit that fills common gaps developers encounter in everyday projects. Essentials emphasizes speed and low footprint, with components such as LongHashMap delivering measurable performance improvements over standard implementations. The library is compatible with both Android and standard Java environments, making it broadly usable across platforms. Overall, Essentials serves developers who want faster and more convenient core utilities without adopting large libraries like Guava or Apache Commons.
