The river rises from its source in central Java at the Lawu volcano, then flows north and eastward to its mouth in the Java Sea near the city of Surabaya. Other major rivers are Brantas, Citarum, Cimanuk and Serayu. 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 most active volcano in Java and also in Indonesia is Mount Merapi, 2,930 metres . Afanasij Nikitin, a merchant from Tver , traveled to India in 1466 and described the land of java, which he called шабайте (shabait/šabajte).
Javan rice terraces have existed for more than a millennium and had supported ancient agricultural kingdoms. The growing human population has put severe pressure on Java’s wildlife, as rainforests were diminished and confined to highland slopes or isolated peninsulas. Some of Java’s endemic species are now critically endangered, with some already extinct; Java used to have Javan tigers and Javan elephants, but both have been rendered extinct. Today, several national parks exist in Java that protect the remnants of its fragile wildlife, such as Ujung Kulon, Mount Halimun-Salak, Gede Pangrango, Baluran, Meru Betiri, Bromo Tengger Semeru and Alas Purwo.

The Java programming language requires the presence of a software platform in order for compiled programs to be executed. Platform-independent Java is essential to Java EE, and an even more rigorous validation is required to certify an implementation. OpenJDK is another notable Java SE implementation that is licensed under the GNU GPL. The implementation started when Sun began releasing the Java source code under the GPL. As of Java SE 7, OpenJDK is the official Java reference implementation.
The programs are written in Java typically run faster than corresponding Python programs and slower than C++. Like C++, Java does static type checking, but Python does not. The Java codes are first compiled into byte code (machine-independent code).
If you look in com/example/tutorial/protos/, you can see that it contains .java files defining a class for each message you specified in addressbook.proto.
