static variable is a class variable which value remains
constant for the entire class?? variable means value is
changed....hear value is not changed... why it is called
static variable
Answer Posted / singh_prabhakar
its a misconception if u think tht static variable's values
are nt changed....it does....!!!
the keyword static only means tht this variable belongs to
the class ie every object tht uses this var is using the
only copy of it wch lies with the class......unlike the
instance variable where when accessed every object enjoys a
copy for itself...
in short --in a class thr's a - "static int k=0;" n class
has three objects -"ob1,ob2,ob3" n say all tends to
increment "+2" to the value of k...then @ end after being
accessed by aal three objects the final value of "k" wud be
"6" ..!!!
