The creators of the language wrote this as the authoritative guide to Java. This updated edition describes the most recent release of the Java programming language, version 1.3 of the Java 2 platform Standard Edition, and has been completely reworked from beginning to end. This third edition has been reorganised to provide more in-depth discussion of the additional language capabilities in addition to interesting examples on using the new core classes like the collections and internationalisation packages. This third edition has undergone more than just API updates. This Third Edition offers special insights into the motivations for and methods for using the Java programming language, straight from the designers. This revised edition will serve as a useful reference for more advanced pupils, who will learn new information about the subtleties of the language. Beginning and intermediate students will benefit from the valuable examples and clear explanations of language and library features.
