In last week's column, I talked about free coffee. This week, I want to talk a little about the other Java.
Over the last few years, perhaps no programming language has been as hyped as Java. The promise was you can write applications once and run anywhere.
For years, people have talked about the need for mainframe application developers to learn Java. COBOL was dead. Just look at the college courses offered in COBOL vs. those in Java.
Often when a new technology comes out, commentators like to pit it against the existing technology. In some cases, they are right. For example, DVRs and DVD players will likely kill the VCR. When I moved recently, I didn't even bother to hook up my VCR.
But look at radio. I'm sure when television came out, pundits predicted radio's demise. It didn't disappear but evolved to fit a niche. Programs such as Gunsmoke and The Guiding Light started out on the radio but ended out on television but radio continued to be an important medium for news and music. To this day, I prefer to listen to a baseball game on the radio than watch it on TV. A good play-by-play man makes the game come alive with just words.
Java's relationship with COBOL is similar. Java didn't slay COBOL. Crafty people learned how to use Java with COBOL to accomplish their goals. A smart person knows how to find the right balance between the old and new.
Do you use a lot of Java at your shop? Do you still use a lot of COBOL? Have you found interesting ways to use them together? If so, please let us know how. You can contact me by clicking here.
