Answer Posted / qim2010
The final Output is
size :4
Size after:2
While called ArrayList.remove() method, in remove method, we
can pass object or index number to remove.
// remove array list element by index number
list.remove(2); //will remove the second element
// remove ArrayList element by Object value
list.remove("2"); //will remove the element
