Java Garbage Collection Basics
This tutorial covers the basics of how garbage collection works with the hotspot jvm. once you have learned how the garbage collector functions, learn how to monitor the garbage collection process using visual vm. finally, learn which garbage collectors are available in the java se 7 hotspot jvm. time to complete. approximately 1 hour. Java garbage collection is the process by which java programs perform automatic memory management. java programs compile to bytecode that can be run on a java virtual machine, or jvm for short. when java programs run on the jvm, objects are created on the heap, which is a portion of memory dedicated to the program. Java garbage collection. in java, garbage means unreferenced objects. garbage collection is process of reclaiming the runtime unused memory automatically. in other words, it is a way to destroy the unused objects. to do so, we were using free () function in c language and delete () in c . but, in java it is performed automatically. Eligibility for garbage collection : an object is said to be eligible for gc(garbage collection) iff it is unreachable. in above image, after i = null; integer object 4 in heap area is eligible for garbage collection. ways to make an object eligible for gc. Java garbage collection is the process by which java programs perform automatic memory management. java programs compile into bytecode that can be run on a java virtual machine (jvm). when java programs run on the jvm, objects are created on the heap, which is a portion of memory dedicated to the program.

The g1 garbage collector is the garbage collection algorithm that was introduced with the 4th update of the 7th version of java and improved since. g1gc was designed to be low latency, but that comes at a price – more frequent work which means more cpu cycles spent in garbage collection. Monitoring garbage collection with the jconsole user interface. the jconsole command launches a graphical interface that shows aspects of a running java application. you can monitor memory use, thread use, and cpu use there, as shown in figure 2. Java full gc means that the full garbage collection event happened. meaning that both the young and old generation was cleared. the garbage collector tried to clear it and the log tells us what the outcome of that procedure was.
