Submitted by Nidhi, on May 23, 2022

Problem Solution:

In this program, we will create a Vector collection with string elements. Then we will get the first element of vector collection using the firstElement() method.

Program/Source Code:

The source code to get the first element of Vector using the firstElement() method is given below. The given program is compiled and executed successfully.

// Java program to get the first element of Vector 
// using the firstElement() method

import java.util.*;

public class Main {
  public static void main(String[] args) {
    Vector < String > vec = new Vector < String > ();

    vec.add("CAR");
    vec.add("BUS");
    vec.add("BIKE");
    vec.add("BUS");
    vec.add("TRUCK");

    System.out.println("First Element: " + vec.firstElement());
  }
}

Output:

First Element: CAR

Explanation:

In the above program, we imported the "java.util.*" package to use the Vector class. Here, we created a public class Main.

The Main class contains a main() method. The main() method is the entry point for the program. And, created a Vector collection vec with string elements. Then we used the firstElement() method to get the first element of vector collection and printed the result.
