<P> Java is divided into four administrative provinces, West Java, Central Java, East Java, and Banten, and two special regions, Jakarta and Yogyakarta . </P> <P> The origins of the name "Java" are not clear . One possibility is that the island was named after the jáwa - wut plant, which was said to be common in the island during the time, and that prior to Indianization the island had different names . There are other possible sources: the word jaú and its variations mean "beyond" or "distant". And, in Sanskrit yava means barley, a plant for which the island was famous . "Yawadvipa" is mentioned in India's earliest epic, the Ramayana . Sugriva, the chief of Rama's army dispatched his men to Yawadvipa, the island of Java, in search of Sita . It was hence referred to in India by the Sanskrit name "yāvaka dvīpa" (dvīpa = island). Java is mentioned in the ancient Tamil text Manimekalai by Chithalai Chathanar that states that Java had a kingdom with a capital called Nagapuram . Another source states that the "Java" word is derived from a Proto - Austronesian root word, Iawa that meaning "home". The great island of Iabadiu or Jabadiu was mentioned in Ptolemy's Geographia composed around 150 CE in the Roman Empire . Iabadiu is said to mean "barley island", to be rich in gold, and have a silver town called Argyra at the west end . The name indicates Java, and seems to be derived from the Hindu name Java - dvipa (Yawadvipa). </P> <P> Java lies between Sumatra to the west and Bali to the east . Borneo lies to the north and Christmas Island is to the south . It is the world's 13th largest island . Java is surrounded by the Java Sea to the north, Sunda Strait to the west, the Indian Ocean to the south and Bali Strait and Madura Strait in the east . </P> <P> Java is almost entirely of volcanic origin; it contains thirty - eight mountains forming an east--west spine that have at one time or another been active volcanoes . The highest volcano in Java is Mount Semeru (3,676 metres (12,060 ft)). The most active volcano in Java and also in Indonesia is Mount Merapi (2,930 metres (9,610 ft)). In total, Java boast more than 150 mountains . </P>
