Java program to remove the first occurrence of the specified element from Vector collection

Given a Vector collection, we have to remove the first occurrence of the specified element.
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 first occurrence of the specified element from vector collection using the removeElement() method.

Program/Source Code:

The source code to remove the first occurrence of the specified element from the Vector collection is given below. The given program is compiled and executed successfully.

// Java program to remove the first occurrence of the 
// specified element from Vector collection

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

Output:

Vector elements: [CAR, BUS, BIKE, BUS, TRUCK]
Vector elements: [CAR, BIKE, 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 removeElement() method to remove the first occurrence of "BUS" from vector vec and printed the updated collection.
