Answer / g.arun
Array is not growable and Arraylist is growable
We can access elements in a Arraylist randomly and in
LinkedList we cannot(means for accessing an element we have
traverse from first elemet in Linkedlist.

Answer / madhu sudana rao
first one:
array is fixed length,arraylist is growing array(means
they have no fixed length , if u add more the size
arraylist size incress and vise versa)
seond one:
if add and remove the elements in the middle takes more
time by using arrylist in that time use linkedlist
arrylist is good for retiveing the elements in specific
position
arraylist is faster than linkedlist for random accesing
of elemnets

Answer / ram
array contain a similar data type and array size is fixed i.e
dynamically its size can't be changed.
but arraylist can store more then one data type and its size
can be changed dynamically.
one major difference is that,array used to store primitive
data type(i.e. int,char etc) while arraylist is used to
store objects.

Answer / sureshkumar
Using array we can stored value by using index.
Using arraylist we can stored value by using key.so we can
retrive the values by using key and we can remove the value
from arraylist by using key.So the array overflow problem
wont happen.
