how do I print the elements in the Arraylist without the null.

[sharon avitan]

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

public void printArray()
    {
        for(int i = 0; i<size; i++)
        {
           
            System.out.println("arr[" + i + "] = " + arr[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().

 public void printArray()
    {
        for(int i = 0; i<size; i++)
        {
            System.out.println( arr[i].toString());
         
         
        }       
    }

in this I get NullPointerException..

in other words...

If the element is not equal to null...
   print it

(that is a hint...)

There is no need to call toString() on the object you are printing. If you try this sort of thing

Foo f = new Foo();
 . . .
System.out.println(f);

You 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).
