Garbage Collection is a feature of Java programming language that automatically manages memory allocation and deallocation for objects created in an eden space.
The Java garbage collection process uses a mark-and-sweep algorithm. Here’s how that works: There are two phases in this algorithm: mark followed by sweep. When a Java object is created in the heap, it has a mark bit that is set to 0 (false). During the mark phase, the garbage ...
Java Garbage Collectionis an automatic process during which the Java Virtual Machine inspects the object on the heap, checks if they are still referenced and releases the memory used by those objects that are no longer needed. Object Eligibility: When Does Java Perform Garbage Collection ...
Garbage collection (GC) is amemoryrecovery feature built into programming languages such asC#andJava. A GC-enabled programming language includes one or more garbage collectors (GC engines) that automatically free up memory space that has been allocated toobjectsno longer needed by the program.
