Ask it something hard.
My Spring Boot app throws LazyInitializationException when I return an Order entity from a controller. Java 17, Boot 3.
CLAUDE · WITH THIS SKILL
You get: the root cause in one sentence (lazy collection serialised after the Hibernate session closed) -> a short explanation of why returning entities from controllers triggers it -> record-based DTOs in a code block -> a transactional service method that maps the entity while the session is open -> a one-line why on avoiding open-in-view -> the single next action: rerun the failing endpoint test.

// what's inside
What's inside this skill
- Compilable Java classes and methods with imports and stated JDK level
- Code reviews ranked by severity with one-line fixes
- Stack trace and failing test diagnosis with the minimal fix
- JUnit 5 tests and Maven or Gradle build repairs
Backend and enterprise developers who write, maintain or review Java code every day.
// what's inside
What you're actually buying
This Claude/ChatGPT skill is a Java AI pair programmer inside your daily coding work: it writes complete, compilable classes and methods for your JDK level, reviews the code you paste with findings ordered by severity, debugs stack traces down to the root cause frame, writes JUnit 5 tests with Mockito and AssertJ, and fixes broken Maven or Gradle builds with the exact pom.xml or build.gradle.kts change.
It knows modern Java idioms (records, sealed types, switch expressions, Streams, java.time, virtual threads), the JVM diagnostics tools, Spring Boot, JPA and the usual concurrency and performance traps. It is a helper in your Java work, not a job-role persona, and it does not compile or run anything itself; it hands you code and the command to verify it.
Works the same way in Claude, ChatGPT and Gemini. One purchase, download the file, install it in under 2 minutes, then paste your code or error and get a fix with the reasoning. Pairs with Henrik, Java Developer, the persona skill; this one is the helper inside Java.
# AI Skill for Java KissMySkills.com | Install: paste this whole file into Claude Projects (Project instructions), a custom GPT (Instructions), a Gemini Gem, or your AI's system prompt. Then just ask questions the way you normally would. ## Who you are You are a senior Java pair programmer sitting next to the user while they write, build, test and debug Java. You know the language, the standard library, the JVM, the build tools and the ecosystem, and you hand over code that compiles, modern idioms, and reviews that catch real defects. You are the helper inside the user's Java work, not a job-role persona. Tone: direct, practical, code first. ## What you know about Java - Language: records, sealed types, enums, generics and wildcards, lambdas and method references, switch expressions and pattern matching, text blocks, var, try-with-resources, checked vs unchecked exceptions. - Standard

Questions about this product
What does the AI Skill for Java do?+
It turns Claude or ChatGPT into a Java AI pair programmer that writes compilable Java code, reviews your classes, explains stack traces, writes JUnit 5 tests and repairs Maven or Gradle builds, always stating which JDK level the code assumes.
Does it compile or run my Java code for me?+
No. It does not execute anything. It gives you the Java code, the build file change or the diagnostic command, and tells you exactly what to run to verify the result yourself.
Which Java versions and frameworks does it cover?+
It asks which JDK you target (8, 11, 17, 21 or newer) and adjusts syntax accordingly. It covers plain Java, Spring Boot, Jakarta EE, JPA and Hibernate, Jackson, Lombok and the common testing stack around JUnit 5.
How is this different from the Java Developer role skill?+
The Java Developer role skill is a full persona for planning and architecture. This Java tool skill is the pair programmer next to you: idioms, stdlib, JVM tooling, build fixes and reviews of the code you are writing right now.
Which AI tools does this skill work with?+
Works with Claude (recommended), Claude Code, ChatGPT, Gemini and Copilot, and any AI chat that accepts system prompts. Claude Projects gives the best results because it remembers your Java version, build tool and project conventions between chats.
Do I have to read it myself?+
No. The file is written for your AI to read, not for you. Upload it or paste it in once and the AI takes on the role. After that you just ask it questions the way you normally would. You're welcome to open it and read it, but nothing here depends on you doing that.
Is this a physical book?+
No, it's digital. You download it the moment the order goes through and it's yours permanently. The cover is styled like a book because each edition is written and edited as one self-contained piece of work. The reading part is your AI's job, not yours.
