    The Art and Science of Java

    This text is an early draft for a general introductory textbook in computer science—a Java-based version of my 1995 textbook The Art and Science of C. My hope is that I can use much of the existing material in writing the new book, although quite a bit of the material and overall organization have to change. At this point, the material is still in a preliminary form, and the feedback I get from those of you who are taking this course will almost certainly lead to some changes before the book is published. One of the central features of the text is that it incorporates the work of the Association of Computing Machinery’s Java Task Force, which was convened in 2004 with the following charter:…

    Java Exam

    Java is a general-purpose, concurrent, class-based, object-oriented computer programming language that is specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere" (WORA), meaning that code that runs on one platform does not need to be recompiled to run on another. Java applications are typically compiled to bytecode (class file) that can run on any Java virtual machine (JVM) regardless of computer architecture. Java is, as of 2012, one of the most popular programming languages in use, particularly for client-server web applications, with a reported 9 million developers. Java was originally developed by James Gosling at Sun Microsystems (which has since merged into Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++, but it has fewer low-level facilities than either of them.…
