OCA: Java SE 8 Programmer 認證課程
課程簡稱：OCA Java Training Course (SE 8)

在現今的應用範圍上，Java 語言可說是十分廣泛，從 Windows、Linux 以至手機，都有應用 Java 技術。因此 Java 已經成為跨平台及網路軟件的首選。事實上 Java 技術的簡單性和跨平台能力使其成為 I.T. 程式編寫界的標準，這亦是 Java 在 I.T. 界認受性廣泛的主要原因。

Java 是物件導向 (Object-Oriented) 開發模式的程式語言。 物件導向開發模式是現今程式語言的主流。Java 作為易學及又有廣泛應用性的程式語言，無疑是初學物件導向開發模式的首選 。通過學習 Java 從而了解物件導向開發模式後，學習其他程式設計語言可以更易上手。

Java 8 在不同方面都對 Java 有新的改進，例如對 Lamda expression 的支援及 Data / Time API 的改動。OCA: Java SE 8 Programmer 認證已把上述提及的兩項列入考試範圍，因此本課程亦會教授包括這兩項新技術的應用。 本中心的 OCA: Java SE 8 Programmer 認證課程籌備多時，精心編排。由上堂、溫習、實習、考試研習、做試題至最後考試，均為你度身訂造，作出有系統的編排。務求真正教識你，又令你考試及格。
