Once it is no longer found in the application code, it is removed by the JVM, and the memory space is made free. What is Java Garbage Collection? Java applications obtain objects in memory as needed. It is the task of garbage collection (GC) in the Java virtual machine (JVM) to automatically determine what memory is no longer being used by a Java application and to recycle this memory for other uses. While a developer can't specifically force Java garbage collection, they can ask the JVM to prioritize the process.

Rich Standard Library - Java includes a vast number of premade objects that can be used to perform such tasks as input/output, networking, and date manipulation. Brief Introduction to Garbage Collection From the name, it looks like Garbage Collection deals with finding and deleting the garbage from memory. However, in reality, Garbage Collection tracks each and every object available in the JVM heap space and removes unused ones. In simple words, GC works in two simple steps known as Mark and Sweep: The Java garbage collection algos are non-deterministic, and while all of these methods can motivate the JVM to do GC, you can't actually force it. If the JVM has too much going on and a stop-the-world operation is not possible, these commands will either error out, or they will run but GC won't actually happen.
