lisp编程语言（国外英文资料） The American valley of silicon valley 1.1.1 Java was born Sun corporations Java language development team was established in 1991 to expand consumer electronics, such as interactive TV and toaster boxes. Sun insiders called the project Green, when the World Wide Web was still on the drawing. The groups leader is James Gosling, a brilliant programmer. He was born in 1957 and joined Sun in 1984, before working for an IBM research institute. Profound experience in the process of research and development, Gosling to consumer electronics products in the development of philosophy and workstation differences: consumer electronics requires high reliability, low cost, standardization, simple to use, the user doesnt care about the CPU model, also do not appreciate the special expensive RISC processors, they need to be based on a standard, a series of optional solution, can be selected from 8086 to 80586. To make the whole system independent of the platform, Gosling starts by rewriting the C compiler. But Gosling felt in the process of rewriting is unable to meet the need of C, only then in June 1991 to start preparing to develop a new language, so give it a name? Gosling looked out of the window and saw an old Oak tree, and named Oak, the precursor of the Java language. Later found Oak is another language of a registered trademark of Sun Microsystems, was renamed the Java, namely a Pacific Ocean islands name, the island produced a kind of taste very delicious coffee. When Gosling started writing Java, it was not limited to the expansion of the language mechanism itself, but also to the software and hardware environment that the language ran. He is going to build a system that the system runs in a large, distributed, heterogeneous grid environment, complete the communication between the various electronic devices to work together. Gosling adopted in the design of the Virtual Machine (Virtual Machine Code), the Java language is compiled to produce a Virtual Ma
