In comparison to other languages, the Java Runtime has several automated memory management features to improve the safety, reliability, efficiency, and ease of programming.
- Users are not required to allocate and reclaim memory when creating objects. The JVM will create objects in the heap.
- Memory is only allocated to objects. References to each object are stored in the stack as required.
- The automatic garbage collector tracks unused objects and reclaims memory back from them in the next collection cycle.
- To release an object, there should be no reference to that object or to any parent of that object in a hierarchical relation like a
- Consequently, releasing a collection without holding on to the objects in that collection will result in the entire collection, including the objects contained within, to be garbage collected.
