Java Trove: High Performance Primitive Collections Trove is a high-performance library for Java that provides primitive collections (like TIntArrayList, THashMap, etc.) as alternatives to Java's standard collections that use object wrappers (like ArrayList or HashMap). Key Features Primitive Collections: Avoids boxing/unboxing overhead by providing collections for primitive types Memory Efficiency: Uses less memory than standard Java collections Performance: Faster than standard collections for primitive operations Common Trove Classes Lists TIntArrayList - int list TLongArrayList - long list TDoubleArrayList - double list Maps TIntIntHashMap - int to int map TIntObjectHashMap - int to object map TObjectIntHashMap - object to int map Sets TIntHashSet - int set TLongHashSet - long set Example Usage Benefits Over Standard Collections No Boxing: Avoids Integer int conversions Less Memory: No object overhead for primitives Better Performance: Faster operations on primitive data Maven Dependency Note: Trove is particularly useful in performance-critical applications that work heavily with primitive data types. However, with Java 8+ improvements to the standard collections and the introduction of streams, the performance gap has narrowed in many cases.
