Does anyone know what version of JDK is most popular now.I need to install one and I originally had jdk 1.5.0 but now I see JDK 6 in the Sun's webpage.Any information on different versions would be usefull
in many cases, jdk 5 will be enough, since currently, using generics and Type safe and totally all jdk 5 features are getting popular but I suggest you to use jdk 6 and don't worry about compatibility of old version styled codes
If you don't know the difference continue on using the JDK 1.5the biggest difference is in JDBC, web services and annotationsalso some extra standards have become part of Java SE in java 6here are two useful brief descriptions: java.sun.com/javase/6/webnotes/features.htmljava.sun.com/.../beta2.html
Better you use the final release of JDK1.5 ... because you will face some compatibility issues using the JDK1.6. But JDK1.6 is 15% to 30% faster then 1.5 ....
