Hi all,
I am using windows and installed jdk 1.6.
It created following directory structure.
Java
|
|----jdk1.6.0_26
|
|----jre6

According to oracle link here.
jdk1.6.0_26 is source directory for java installation and it contains the required jre.

Now I have doubt jre6 directory stands for what ?.
Is it useless ?.
Which is real jvm jre6 or jdk1.6.0_26\jre ?

Thanks in advance.

jdk stands for "Java Development Kit"

jre stands for "Java Runtime Environment"

Since the jdk includes the jre perhaps the jre is also separate intended for people who just want to use Java programs -- not develop them.
