CiNii 図書 - Java : an introduction to problem solving & programming

For introductory Computer Science courses using Java, and other introductory programming courses in departments of Computer Science, Computer Engineering, CIS, MIS, IT, and Business. Students are introduced to object-oriented programming and important concepts such as design, testing and debugging, programming style, interfaces inheritance, and exception handling. The Java coverage is a concise, accessible introduction that covers key language features. Objects are covered thoroughly and early in the text, with an emphasis on application programs over applets. Updated for Java 7, the Sixth Edition contains additional programming projects, case studies, and VideoNotes. MyProgrammingLab, Pearson's new online homework and assessment tool, is available with this edition.
