When does the JVM start the automatic memory release process?

The process of automatic memory management in JVM, known as Garbage Collection, runs automatically when the system detects that available memory is starting to run out or when certain memory usage thresholds are exceeded. JVM tracks objects that are no longer reachable from root references (such as from the stack or static variables) and runs the garbage collector to free the memory occupied by these objects. This process occurs in the background and can be triggered multiple times during the program's execution, depending on settings and application behavior.
