Java and C
Java – once the great white hope of the Internet, Java is a complex object-oriented compiled language used to produce functional chunks of binary code called ‘applets’ which can be embedded in web pages. Originally appearing in 1995, Java was widely hyped as a platform-neutral system which would allow programs to run in a range of environments without modification, but its slow performance and user-unfriendly syntax disappointed many would-be users, and much of its audience was stolen by friendlier programming environments like Macromedia (now Adobe) Flash. Recent improvements in speed and programmer-friendliness may see Java re-emerge as a contender.
