  1. import java.util.*;
    class ArryLst{
    public static void main(String ...args){
    ArrayList al=new ArrayList();
    System.out.println("size= "+ al.size());
    }
    }
    Output: this gives size=0.
    here size() returns the number of element in the list.

    ////////////...............

    StringBuffer default size is 16.

  3. Your program returns 0 because there is no elements in your object al. The size returns the number of elements in the list.
