Static block is the block which is executed first in the 
program. Static variable is the common variable which is 
shared by all the objects. Static variable is not specific 
to any object.

i wolud like a new point to the above answer.
first the static varibles are inistalized then the static 
bloks are executed.

staticblock,static variables,static method are executed 
before creating an object to be created to class.i think 
there is no difference between them.

static block is used to initialize the variables during the 
Jvm start up.
static variable is used to declare the class level 
variables whose value remains ame for the whole class.
