Ever wondered how Java keeps track of memory usage and cleans up after unused objects? The answer lies in garbage collection, a fundamental Java mechanism that automatically reclaims memory occupied by objects no longer referenced by your program.<\/p>\n

Understanding garbage collection is essential for writing efficient and memory-conscious Java applications. This blog post delves into the world of Java garbage collection, exploring when objects become eligible for collection and the different algorithms used by the Java Virtual Machine (JVM) to manage memory.<\/p>\n
