JAVA program for Vector.indexOf() Method

This JAVA program is to demonstrate the use of Vector.indexOf() method.

The indexOf() method returns the index  of the element specified in the brackets.

Note : If the element at the index specified in the brackets is not present, then it returns -1.

Program

import java.util.*;

class v8
{
	public static void main(String args[])
	{
		Scanner sc = new Scanner(System.in);
		int i,n;
		Vector<Integer> v = new Vector<Integer>();				
		System.out.println("how many elements do you want to insert?");
		n=sc.nextInt();
		
		System.out.println("Start inserting the elements");
		for(i=0;i<n;i++)
		{
			v.add(sc.nextInt());		
		}
		System.out.println("Enter the element of which you want to find the index of");
		int el = sc.nextInt();
		System.out.println("Index Of element("+el+") in the Vector = "+v.indexOf(el));
	}
}
