Jan 12, 2010 · An object graph is some graph whose nodes are objects, and whose edges are relationship of interest between the objects. In the case of the Java garbage collector, the object graph of concern is the graph of reachable objects.

Dec 12, 2017 · The large-scale sawtooth pattern represents the memory utilization between GC cycles. The application is allocating objects steadily (the upsloping line) until the heap gets full enough for the VM to decide to run the GC (the point).

Oct 15, 2021 · Automatic Garbage Collection in Java enhances application performance by providing insights through GC Logs. These logs reveal vital details about each GC event, aiding optimization and debugging. Various GC algorithms exist, each with distinct log formats.

Oct 26, 2021 · In this post, let me share few interesting Garbage collection patterns that have intrigued me. 1. Healthy saw-tooth pattern. You will see a beautiful saw-tooth GC pattern when an...

Aug 28, 2011 · The garbage collection is about objects, not variables. Further, it’s worth noting that this pattern is not specific to the young generation, but will occur every time you have multiple allocations but a single freeing operation.

Nov 1, 2024 · When building low-latency Java applications, understanding how coding choices impact garbage collection (GC) behaviour is crucial. Certain patterns and coding styles can inadvertently...

May 1, 2020 · Garbage collection is done by a daemon thread called ‘Garbage Collector’ which directs the objects through different spaces within the heap. Garbage Collection is done in 3 steps.

Apr 8, 2025 · There are generally four ways to make an object eligible for garbage collection. Nullifying the reference variable (obj = null). Re-assigning the reference variable (obj = new Object ()). An object created inside the method (eligible after method execution).

Garbage collection in Java is an automatic memory management process that helps reclaim memory that is no longer in use. This allows developers to focus more on writing code rather than dealing with memory allocation and deallocation explicitly.

Garbage collection is a vital aspect of Java programming that ensures efficient memory management in applications. This guide aims to provide an in-depth understanding of garbage collection, its processes, and its implications for performance and optimization.
