          ArrayList objArray = new ArrayList();
          ArrayList objArray2 = new ArrayList();
          objArray2.add(0,"common1");
          objArray2.add(1,"common2");
          objArray2.add(2,"notcommon");
          objArray2.add(3,"notcommon1");
          objArray.add(0,"common1");
          objArray.add(1,"common2");
          objArray.add(2,"notcommon2");
          System.out.println("Array elements of array1" +objArray);
          System.out.println("Array elements of array2" +objArray2);
          objArray.removeAll(objArray2);
          System.out.println("Array1 after removing
