VectorExample.java

import java.util.Vector;

/*
 *  Example of indexOf(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);
        vector.add(40);
        vector.add(30);
        vector.add(50);

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

        /*
         * Returns the index of the first occurrence of the specified element in
         * this vector, or -1 if this vector does not contain the element.
         */

        int indexPosition = vector.indexOf(30);

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

    }
}

Output

vector  : [10, 20, 30, 40, 30, 50]

indexPosition  : 2
