Garbage Collection in Java allows developers to focus on writing code without worrying about memory management, making Java a popular choice for building complex and large-scale applications. However, understanding how Garbage Collection works is essential for Java developers to optimize their code's pe...
Interfaces:The abstract data types are referred to as interfaces in Java. They allow Java collections to be manipulated in a way that is not tied to the specifics of their representation. The Set represents the sorted collection of elements. In addition, object-oriented programming languages form...
Before going into Java Garbage Collection tuning we need to understand two things. First of all, how garbage collection works in theory and how it works in the system we are going to tune. Our system’s garbage collector work is described by garbage collector logs and metrics from observabilit...
Before diving into the world of HashMaps in Java, it is advisable to have a basic understanding of Java programming concepts, including variables, data types, loops, and conditional statements. A grasp of key data structures like arrays and lists will lay a solid foundation. Familiarity with ...

What is garbage collection (GC)? 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 ...

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 ...
