Essential Java for Scientists and Engineers

Brian D. Hahn, Katherine M. Malan9780750654227, 0-7506-5422-8

Essential Java serves as an introduction to the programming language, Java, for scientists and engineers, and can also be used by experienced programmers wishing to learn Java as an additional language. The book focuses on how Java, and object-oriented programming, can be used to solve science and engineering problems.Many examples are included from a number of different scientific and engineering areas, as well as from business and everyday life. Pre-written packages of code are provided to help in such areas as input/output, matrix manipulation and scientific graphing.Java source code and solutions to selected exercises are available at: www.bh.com/companions/0750659912A free solutions manual is available to lecturers at: http://textbooks.elsevier.com* Takes a ‘dive-in’ approach, getting the reader writing and running programs immediately* Teaches object-oriented programming for problem-solving in engineering and science* Fully supported with online resources and listings to download
