Answer / ravindra reddy
The size of the arraylist will increase to 150 why because
in arraylist the elements are reach to initial size of the
array list then size will be increase to half of the
capacity

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..

Answer / srinu
Arraylist are growble nature.so present capacity of arraylist
100 then add an 101 element then that time current capacity
is formula
(101*3/2)+1=151

The Size of the arraylist will become 101 only once you call suppose al.size() but it will calculate it's capacity like below:
New Capacity = (current capacity*3/2)+1

Answer / saty
It is undocumented by sun/oracle. Also it varies from one
java cersion to another..... in Java 6==>
(100*3)/2+1
| Is This Answer Correct ? | 0 Yes | 3 No |
Answer / satish
from the Java Source code of ensureCapacity() API,
int newCapacity = (oldCapacity * 3)/2 + 1;
So, (100 *3)/2 + 1 will be the answer.

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.
