Trying to overcome the obsolescence

Java float and double primitive types are evil. Don’t use them.

Hi people!

I’m right back here again from holidays and after some weeks without publishing anything I want to resume the work with a short post talking about java primitive types float and double.  Today is an easy post for begginers. No web, no application servers, no JavaServer Faces. A simple lesson about Java SE.

Today I was talking with a colleague at work. He was showing me a Java class, and I noticed that he was using a Double class variable to store some floating point values that were coming from a database. A long time ago I had a bad experience with float and double types when doing a database migration that gave me some hours of headache. I pointed him that he should use BigDecimal instead of that evil things. Fortunately he followed my advice.

I will explain here why I hate float and double primitive types in Java. Why I think they shouldn’t exist. Follow this link and you will learn the reason of my obsession against these “poor innocent” types.

As always I will be very proud to have any comment, any word encouragement, any gift, any million of euros. Every kind of feedback will be greatefully wellcomed.
