Java-Editor is an integrated environment for Java development, designed for school teaching and home use on lower-specification computers. Its class modeler reads source files, shows classes with attributes and methods, and can transfer model changes back into code. The UML window lets users create objects and test methods or attributes without writing a main method. A GUI designer supports AWT, Swing, and JavaFX components and synchronizes form changes with source code. The structogram editor makes control-flow diagrams, can generate programs or methods, and includes a puzzle mode for students. Debugging features include breakpoints, stepwise execution, watch expressions, local variables, parameters, and call-stack information. Additional menus become available when Git, Subversion, or JUnit is installed. Built-in LLM support includes OpenAI and Gemini cloud models and local models through Ollama. OpenAI use requires an API key and paid account or credits; local models require suitable CPU, GPU, and disk space. Java-Editor is free for personal, commercial, and government use, but requires a Java Development Kit. For JDK 11 and later, JavaFX must be installed separately.
Who it is for
Java-Editor suits students and teachers learning Java, as well as home users working on lower-specification computers. Its classroom deployment options include portable USB installations and network-folder deployment.
What is good

- UML tests work without a main method.
- Structograms can generate Java programs or methods.
- Debugger includes breakpoints and watch expressions.
- Free for personal, commercial, and government use.
What to know first
- A Java Development Kit is required.
- JavaFX must be installed separately for JDK 11 and later.
- OpenAI assistance requires an API key and paid account or credits.
- macOS support uses CrossOver or virtualization.
Verdict
