Submitted by Nidhi, on May 24, 2022

Problem statement

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.

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.
