This involves different memory components like Heap, Metaspace, and Code Cache, each serving specific roles. Generational Garbage Collection (GC) helps efficiently manage memory by classifying objects into short-lived and long-lived categories. Common problems include memory leaks, high object creation rates, and improperly sized memory sections. Tools such as JVisualVM, JConsole, and Java Mission Control are recommended for monitoring and troubleshooting memory issues. 26 [See all Javarevisited archives](/sources/javarevisited/best-of) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@graph":[{"@type":"CollectionPage","@id":"https://daily.dev/sources/javarevisited/best-of/2025/05#page","url":"https://daily.dev/sources/javarevisited/best-of/2025/05","name":"Best Javarevisited Posts — May 2025","description":"The most upvoted Javarevisited posts from May 2025, curated by the daily.dev community.","isPartOf":{"@type":"WebSite","url":"https://daily.dev"}},{"@type":"ItemList","@id":"https://daily.dev/sources/javarevisited/best-of/2025/05#items","numberOfItems":9,"itemListElement":[{"@type":"ListItem","position":1,"url":"https://daily.dev/posts/microservices-architecture-reim9158v","name":"Microservices Architecture"},{"@type":"ListItem","position":2,"url":"https://daily.dev/posts/top-6-books-for-ai-and-machine-learning-engineers-in-2025-kzsq2zd3i","name":"Top 6 Books for AI and Machine Learning Engineers in 2025"},{"@type":"ListItem","position":3,"url":"https://daily.dev/posts/the-concurrency-multithreading-bible-for-engineers-akmb0n7kn","name":"🧠 The Concurrency & Multithreading Bible for Engineers"},{"@type":"ListItem","position":4,"url":"https://daily.dev/posts/mastering-java-optional-from-boring-null-checks-to-elegant-code-blceqmvfc","name":"Mastering Java Optional: From Boring Null Checks to Elegant Code"},{"@type":"ListItem","position":5,"url":"https://daily.dev/posts/bringing-ai-to-java-why-spring-ai-is-a-game-changer-3jmp8tnxt","name":"Bringing AI to Java: Why Spring AI is a Game Changer"},{"@type":"ListItem","position":6,"url":"https://daily.dev/posts/top-5-courses-to-learn-langchain-and-build-ai-powered-apps-in-2025-hqlw45jrl","name":"Top 5 Courses to Learn LangChain and Build AI-Powered Apps in 2025"},{"@type":"ListItem","position":7,"url":"https://daily.dev/posts/top-7-udemy-courses-to-learn-prompt-engineering-in-2025-iawjdjgwl","name":"Top 7 Udemy Courses to Learn Prompt Engineering in 2025"},{"@type":"ListItem","position":8,"url":"https://daily.dev/posts/10-most-important-maven-commands-nc88znyci","name":"10 Most important Maven Commands"},{"@type":"ListItem","position":9,"url":"https://daily.dev/posts/understanding-jvm-memory-architecture-and-guidelines-and-tools-for-troubleshooting-h4cbh4daw","name":"Understanding JVM Memory architecture and guidelines and tools for troubleshooting"}]},{"@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Sources","item":"https://daily.dev/sources"},{"@type":"ListItem","position":3,"name":"Javarevisited","item":"https://daily.dev/sources/javarevisited"},{"@type":"ListItem","position":4,"name":"Best of","item":"https://daily.dev/sources/javarevisited/best-of"},{"@type":"ListItem","position":5,"name":"May 2025"}]}]} ```
