including insertion, sorting, searching, manipulation, and deletion, are possible with Java Collections. A collection in Java is a group of related objects. The Java Collection Framework offers numerous classes (List, Queue, Set, and Deque) and interfaces (Vector,...
Before the Java language appeared, programmers devoted themselves to writing C or C++ programs. At such a time, a seriously contradictory phenomenon existed. When creating objects in C++ and other languages, you had to constantly allocate space. When you did not use these objects, you then had...
In Java, when an object no longer referenced, the Java runtime environment runs the object’s finalize() method before reclaiming the object’s memory. The programmer can also force this process synchronously by calling the following method: ...

Garbage collection is a key feature for developers who build and compile Java programs on a Java Virtual Machine, or JVM. Java objects are created on the heap, which is a section of memory dedicated to a program. When objects are no longer needed, the garbage collector finds and tracks ...
In java garbage collection tutorial, we will learn about object life cycle, difference between mark-sweep, mark-sweep-compact and mark-copy mechanisms, different single threaded and concurrent GC algorithms (e.g. G1), and various flags to control the gc algorithm’s behavior and log useful inf...
