Java program to remove an element from Vector collection based on the specified index

Given a Vector collection, we have to remove an element from Vector collection based on the specified index.
Submitted by Nidhi, on May 24, 2022

Problem Solution:

In this program, we will create a Vector collection with string elements. Then we will remove the element from vector collection based on the specified index using the removeElementAt() method.

Program/Source Code:

The source code to remove an element from the Vector collection based on the specified index is given below. The given program is compiled and executed successfully.

// Java program to remove an element from Vector collection 
// based on the specified index

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("Vector elements: " + vec);

    vec.removeElementAt(2);

    System.out.println("Vector elements: " + vec);
  }
}

Output:

Vector elements: [CAR, BUS, BIKE, BUS, TRUCK]
Vector elements: [CAR, BUS, BUS, TRUCK]

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 removeElementAt() method to remove an element from vector vec at index 2 and printed the updated collection.
