import java.util.*; public class MyClass { public static void main(String[] args) { //creating a vector Vector<Integer> MyVector = new Vector<Integer>(); //populating vector MyVector.add(10); MyVector.add(20); MyVector.add(30); //checking the presence of elements for(int i = 5; i <= 20; i += 5) { if(MyVector.contains(i)) System.out.println(i +" is present in MyVector."); else System.out.println(i +" is NOT present in MyVector."); } } }
