BlueJ 5.3.0

BlueJ 是一套專為 Java 程式語言設計的整合開發環境，主要鎖定初學者與教育用途。它最大的辨識度在於物件導向視覺化功能，能將類別與物件之間的關係以圖形方式呈現，讓學習者更容易理解抽象概念。介面設計走簡潔路線，降低入門門檻，由 Kent 大學團隊開發，長期以來在教學領域累積了不錯的評價，雖然更新頻率不算頻繁，但仍持續維護中。

這套工具最適合剛接觸 Java 或物件導向程式設計的學生，以及需要帶領學生入門的教師。在課堂示範或自學練習的情境下，它的視覺化輔助比一般專業 IDE 更直覺，但相對地，進階開發功能就比較精簡，若需要大型專案管理或外掛生態，可能得轉向其他主流 IDE。授權為開源軟體，提供 Windows 與 macOS 版本，不過目前僅支援英文介面，使用前需留意語言需求。
