Answer / siri

remember.. there are 2 things involved.. capacity and size..
capacity represents how many max elements the list can
accomodate in it, size represents how many elements are
present currently in the list..the capacity is automatically
increased by certain amount (10, 20, 30..) based on the
current size once the size is equal to capacity..

if arraylist size is increased from initial size what is the size of arraylist...suppose initial i..

Answer / anjani

when we create the arraylist, we have two factors
1- inital size of array list,
2 - load factor (default is .75).

load factor means size of the arraylist will be doubled if
we fill 75% of the size availabe.

i mean if intial size of arraylist is 100 then when we will
insert 75th element in the arraylist, its size will be doubled.
