摘要(Abstract)
Java是一门面向对象编程语言，不仅吸收了C++语言的各种优点，还摒弃了C++里难以理解的多继承、指针等概念，因此Java语言具有功能强大和简单易用两个特征。Java语言作为静态面向对象编程语言的代表，极好地实现了面向对象理论，允许程序员以优雅的思维方式进行复杂的编程 [1] 。
Java具有简单性、面向对象、分布式、健壮性、安全性、平台独立与可移植性、多线程、动态性等特点 [2] 。Java可以编写桌面应用程序、Web应用程序、分布式系统和嵌入式系统应用程序等 [3] 。
Java (Indonesian: Jawa; Javanese: ꦗꦮ; Sundanese: ᮏᮝ) is an island of Indonesia, bordered by the Indian Ocean on the south and the Java Sea on the north. With a population of over 141 million (Java only) or 145 million (including the inhabitants of its surrounding islands), Java is the home to 56.7 percent of the Indonesian population and is the world's most populous island.[1] The Indonesian capital city, Jakarta, is located on its northwestern coast. Much of Indonesian history took place on Java. It was the centre of powerful Hindu-Buddhist empires, the Islamic sultanates, and the core of the colonial Dutch East Indies. Java was also the center of the Indonesian struggle for independence during the 1930s and 1940s.
