<ul><li>Garbage Collection (GC) in Java is an automatic process that removes unused objects in the Heap memory space, eliminating the need for manual memory management.</li><li>In Java, objects are considered garbage when no part of the program can reach them, and GC works in three main phases: Mark Phase, Sweep Phase, and Compact Phase.</li><li>Memory in Java is divided into Generations like Young Gen and Old Gen, where objects initially go to Young Gen and then to Old Gen after surviving several GC cycles.</li><li>Various GC strategies like Serial, Parallel, CMS, G1, and ZGC offer different benefits such as low pause times, better throughput and low latency balance, and ultra-low latency, catering to different use cases and applications.</li></ul>
