import java.util.Vector;

/*
 *  Example of  contains(Object o) method 
 */
public class VectorExample
{

    public static void main(String[] args)
    {
        Vector<Integer> vector = new Vector<Integer>();

        vector.add(10);
        vector.add(20);
        vector.add(30);

        System.out.println("vector  : " + vector + "\n");

        /*
         * Returns true if this vector contains the specified element
         */
        boolean isExist = vector.contains(20);

        System.out.println("is '20' Exist in vector : " + isExist + "\n");

        isExist = vector.contains(500);

        System.out.println("is '500' Exist in vector : " + isExist);

    }
}

Output

vector  : [10, 20, 30]

is '20' Exist in vector : true

is '500' Exist in vector : false
