    (1) 

       ArrayList list = new ArrayList <>();`     
   list.add("ffffd");
   list.add(2);
   list.add(11122.33);    
   System.out.println(list);

     ArrayList arraylist = new ArrayList();
 arraylist.add(5);        
 arraylist.add("saman");     
 arraylist.add(4.3);        
 System.out.println(arraylist);
