                + isExist + "\n");

        System.out
                .println("#########################################################"
                        + "\n");

        ArrayList<String> arrayList2 = new ArrayList<String>();
        arrayList2.add("Ram");
        arrayList2.add("Raju");

        System.out.println("ArrayList2 : " + arrayList2 + "\n");
        
        isExist =arrayList.containsAll(arrayList2);
        
        System.out.println("Is ArrayList2 elements are there in ArrayList : "
                +isExist );

    }
}

Output

ArrayList : [Ram, Dave, Peter, Julia, Akram]

ArrayList1 : [Ram, Julia]

Is ArrayList1 elements are there in ArrayList : true

#########################################################

ArrayList2 : [Ram, Raju]

Is ArrayList2 elements are there in ArrayList : false
