I am want to print this arraylist with out the null.
i


this is what I get:
The array is:
arr[0] = Papa Bill
arr[1] = Ali Baba
arr[2] = Ming the Merciless
arr[3] = Grandpa
arr[4] = Tornado
arr[5] = null

I also tried doing this with a toString().



in this I get NullPointerException..

There is no need to call toString() on the object you are printing. If you try this sort of thingYou will get whatever the toString method in the Foo class returns. You won't get any Exceptions, not even if you try to print null, as explained here (and here).
