print ArrayList that contains StringBuffer objects

Question

I have an ArrayList, that stores objects of StringBuffer class. Now I want to print that ArrayList. How could I do that.

Iterator itr=al.iterator(); 
while(itr.hasNext())
{  
    System.out.println(itr.next()); 
}

This just prints the last object for al.size times. Also if you could please tell me why it only prints the last object's value

Answer 1

public class Test {

    public static void main(String[] args) {

        ArrayList al = new ArrayList();
        al.add(new StringBuffer("keshav"));
        al.add(new StringBuffer("sharma"));

        Iterator itr = al.iterator();
        while (itr.hasNext()) {
            System.out.println(itr.next());
        }

    }

}

Its working fine for me.

output:

keshav
sharma
