regarding j2sdk,jre,jdk
Hi,
I have one doubt regarding java components .
Why do we need to install jre even after we have j2sdk which has all java commands to compile and run java classes?
there is another component jdk1.5 ? is this collection of j2sdk and jre?
please clear my doubts with there.. what each componet is for ? why do we need all of them ? whats the purpose of having each of them..

Hi Pannar,
The JDK is the same thing as the J2SDK. Original, the development kit was called the JDK. Somewhere along the line the system was renamed "Java 2", and the JDK became the J2SDK. These days the terms are used interchangably.
The JRE is just the runtime i.e. it does not include the javac compiler, among other things.
You are right however: the JDK/J2SDK includes all the components required for running Java, as well as compiling it, which means if you have the JDK/J2SDK you don't need the JRE.
