public static void main(String[] args) {
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");
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) );
}
}
Result:
The above code sample will produce the following result.
Array elements of array1[common1, common2]
Array elements of array2[common1, common2, notcommon, notcommon1]
Array 1 contains String common2?? true
Array 2 contains Array1?? false
