This commit implements the `div` method in `src/staticAnalyzer/Variable.java` to correctly handle abstract domain arithmetic for division. Key changes: - Implemented logic for `div` method: result inherits `safe` and `edge` constraints from the dividend (this), as integer division results in a value less than or equal to the dividend (assuming positive divisor). - Added null checks for `safe` and `edge` lists to prevent NullPointerException. - Removed TODO marker.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs.

This commit implements the `div` method in `src/staticAnalyzer/Variable.java` to correctly handle abstract domain arithmetic for division. It also includes a new test file `src/staticAnalyzer/VariableTest.java` to verify the implementation. Key changes: - Implemented `div` logic: result inherits `safe` and `edge` constraints from the dividend (this), as integer division results in a value less than or equal to the dividend (assuming positive divisor). - Added null checks for `safe` and `edge` lists to prevent `NullPointerException`. - Added `src/staticAnalyzer/VariableTest.java` with comprehensive test cases (basic division, constraint propagation, null safety, TOP value).
Implemented the
divmethod insrc/staticAnalyzer/Variable.java. The implementation correctly propagatessafeandedgeconstraints from the dividend to the result, as the result of integer division (by a value >= 1) is less than or equal to the dividend. Added null checks to prevent NPEs. Verified with a reproduction test case (which was deleted before submission).PR created automatically by Jules for task 3671879571882173313 started by @mellon85
