Hi Ravi,

How do you? Long, since heard from you.
Nice doubt Ravi! I often came across people having this doubt in common. Please find my comments below.

JDK/J2SDK – JDK is a SDK for Java. After standardizing Java as a ‘technology’ JDK was re-branded to J2SDK. Yes, they are same (alias).

Java/J2SE – Earlier Java release went like Java1.1, Java1.3 and etc. Later up on, Java releases are standardized as J2SE. So, J2SE1.5 or Java 1.5 or J2SE5.0 or Tiger – they refer to same thing – ‘A version of Java release’. Also, Sun used to give pet names to Java releases like Tiger (Java1.5) and Mustang (Java1.6) and Dolphin (Java1.7 – coming soon).

Ravi, If I am not wrong, JDK is obsolete name, and Sun will no more use the name ‘JDK’.So, you can download J2SDK’s instead of JDK.Doesn’t matter, it’s an alias name for JDK.

If you don’t bother, I am blogging this mail, hoping it would be useful!

Mani,
Is j2se1.4 is the java 2 standard edition is one and the same as the jdk1.4 java development kit and the j2sdk1.4 is the java 2 software development kit. Am I right.
My understanding is j2se1.4 and jdk1.4 is the same and the j2sdk1.4 is different.
The following which depicts the same I think.

Mani when I tried to download the jdk1.4 for Linux it takes me to download the j2sdk1.4. I don’t want j2sdk to be installed in the machine , I want only jdk. Where to download , in sun site it takes me like that.
Thanks,
Ravi.
