A classic 3-field POJO runs roughly 9x more tokens than the Lombok equivalent and 19x more than a Java record. The post walks through how Lombok annotations (@Data, @Builder, @Value) and native Java records dramatically reduce code size, then covers other modern Java features — var, text blocks, switch expressions, pattern matching instanceof, and sealed classes — that further shrink the code you feed to a model. The practical takeaway: prefer records for immutable DTOs, use Lombok for mutable objects, and adopt modern Java syntax to reclaim context budget for actual logic and conversation. ## Full article daily.dev links to this article rather than hosting it.

(For Lombok it's just a matter of replacing `@Data` with `@Value`. ## Similar posts on daily.dev - [Introduction to Java records: Simplified data-centric programming in Java](https://daily.dev/posts/introduction-to-java-records-simplified-data-centric-programming-in-java-gszihuhno) · InfoWorld · 3 upvotes · 0 comments --- Tags: [#java](https://daily.dev/tags/java) [View this post on daily.dev](https://daily.dev/posts/the-java-features-that-quietly-save-you-tokens-zh1hl6cfk) ```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","@type":"TechArticle","headline":"The Java Features That Quietly Save You Tokens","url":"https://daily.dev/posts/the-java-features-that-quietly-save-you-tokens-zh1hl6cfk","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/the-java-features-that-quietly-save-you-tokens-zh1hl6cfk"},"datePublished":"2026-07-17T20:06:53.099Z","dateModified":"2026-07-18T08:17:33.226Z","description":"Java's verbosity has a hidden cost when working with LLMs: boilerplate-heavy POJOs consume far more tokens than necessary when pasted into a model's context...","image":"https://media.daily.dev/image/upload/s--ZrL_HSsR--/f_auto/v1722860399/public/Placeholder%2006","thumbnailUrl":"https://media.daily.dev/image/upload/s--ZrL_HSsR--/f_auto/v1722860399/public/Placeholder%2006","isAccessibleForFree":true,"articleSection":"Medium","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Medium","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/medium","url":"https://daily.dev/sources/medium_js"},"commentCount":2,"discussionUrl":"https://daily.dev/posts/the-java-features-that-quietly-save-you-tokens-zh1hl6cfk","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":10},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":2}],"keywords":"java","timeRequired":"PT7M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Medium","item":"https://daily.dev/sources/medium_js"},{"@type":"ListItem","position":3,"name":"The Java Features That Quietly Save You Tokens"}]} {"@context":"https://schema.org","@type":"WebPage","@id":"https://daily.dev/posts/the-java-features-that-quietly-save-you-tokens-zh1hl6cfk","comment":[{"@type":"Comment","text":"very relevant","datePublished":"2026-07-20T07:54:04.571Z","url":"https://daily.dev/posts/zH1Hl6CFK#c-Sg7Y3JshG","author":{"@type":"Person","name":"Jakub Michalik","url":"https://daily.dev/asyd","image":"https://avatars.githubusercontent.com/u/44025800?v=4"}},{"@type":"Comment","text":"Minor point: Mutability is mentioned but in the comparison the POJO is mutable and the record is not which skews the numbers a little.
