جاوا JAVA یکی از محبوب‌ترین زبان‌های برنامه‌نویسی دنیا است و بدون اغراق می‌توان آن را از کارآمد‌ترین زبان‌های برنامه‌نویسی سطح بالا دانست. ماشین مجازی جاوا (JVM) برنامه‌ای است که بایت‌کدهای زبان جاوا را مطابق با سیستم‌عاملی خاص کامپایل کرده و آن‌ها را برای اجرا در سطح سیستم‌عامل آماده می‌کند. شعار اصلی جاوا این است: "یک بار بنویس، همه جا اجرا کن". در حقیقت شما یک بار برنامه را می‌نویسید و به کمک ماشین مجازی جاوا (JVM) آن را در سایر پلتفرم‌ها اجرا می‌کنید. به همین دلیل است که می‌گوییم جاوا یک زبان چند‌سکویی (Cross Platform) است.
Java SE (Standard Edition) که در اصل Java SE API است، به نوعی هسته تمام پلتفرم های جاوا است و به همین دلیل قابلیت های پایه ای دو پلتفرم دیگر، توسط SE فراهم می‌شود. این پلتفرم که با نام J2SE نیز شناخته شده است، شامل کتابخانه های اصلی زبان برنامه نویسی جاوا است. مولفه‌های این پلتفرم، شامل کیت توسعه جاوا (JDK)، محیط زمان اجرای جاوا (JRE) و رابط برنامه‌نویسی کاربردی (API) این پلتفرم است. کیت توسعه جاوا، شامل JRE، کامپایلرها و اشکال زداهایی است که برای توسعه اپلت‌ها و برنامه‌های کاربردی موردنیاز است. محیط زمان اجرا هم کتابخانه‌ها، ماشین مجازی جاوا و سایر مولفه‌های موردنیاز برای اجرای اپلت و برنامه‌های جاوا را شامل می‌شود. از ویژگیهای این پلتفرم، قابلیت استفاده در ساخت برنامه های گرافیکی و بازی ها، کیت های درون تلفن ها و لوازم خانگی و برنامه های دسکتاپ و برنامه های همگانی است.
علاقه مندان و متخصصان این حوزه، می توانند در این دوره ی تخصصی شرکت نموده، پس از اخذ آموزش های تخصصی و تجربه عملی، مدرک معتبر دریافت نمایند.
