   objArray.add(0,"common1"); objArray.add(1,"common2");
   System.out.println("Array elements of array1"+objArray);
   System.out.println("Array elements of array2"+objArray2);
   System.out.println("Array 1 contains String common2?? " +objArray.contains("common1"));
   System.out.println("Array 2 contains Array1?? " +objArray2.contains(objArray) );
