Sun Microsystems Inc chief executive Scott McNealy reckons the Java programming language gives his company a competitive edge in the battle of the Millennium. I think in the next couple of years you’re going to see a lot of people re-engineer for the year 2000 by going to a Java-based environment, he told Reuter after a one-day visit to unspecified Finnish clients. Not missing the chance to bad-mouth Microsoft Corp, said that In three to four years from now NT might actually be ready and we might have some competition – I’m really incredibly excited that we are already in 1997, he said, citing delays in the release of version 5.0 of Windows NT.
