Chapter 3. Using Java > 3.2 THE JAVA LANGUAGE

3.2 THE JAVA LANGUAGE

Java is an object-oriented language that was developed and released by Sun Microsystems in 1995, based upon the earlier Oak (1991), which had been intended for television set-top box software. Oak never took off since services such as video-on-demand failed to develop at the time, but along came Java. The basic core of the language is small, but it is made powerful and versatile by the development of additional 'packages' of code for specific purposes. Its syntax is similar to that of C/C++, but it has significant differences from these languages, one of which is as follows:

When a program is created in C or C++ or a language such as Pascal, its statements must be compiled into low-level instructions for the processor on which it is to be run; each family of processors has its own instruction set. These low-level instructions are then executed by that processor. This means if the program is to run on a different family of processors, the high-level code must be recompiled.
