Java program to remove a specified item from Vector collection

Given a Vector collection, we have to remove a specified item from it.
Submitted by Nidhi, on May 19, 2022

Problem Solution:

In this program, we will create an object of the Vector class to store different types of objects. Then we will add objects using add() method. After that, we will remove a specified item from the Vector collection using the remove() method and print the updated vector.

Program/Source Code:

The source code to remove a specified item from the Vector collection is given below. The given program is compiled and executed successfully.

// Java program to remove an item from 
// Vector collection

import java.util.*;

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

    vec.add(10);
    vec.add(20.5);
    vec.add(true);

    System.out.println("Vector Elements:");
    for (Object obj: vec) {
      System.out.println("  " + obj);
    }

    vec.remove(20.5);

    System.out.println("Updated Vector Elements:");
    for (Object obj: vec) {
      System.out.println("  " + obj);
    }
  }
}

Output:

Vector Elements:
  10
  20.5
  true
Updated Vector Elements:
  10
  true

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 an object vec of the Vector class. Then we used add() method to add items to the Vector collection. After that, we removed the specified item from the vector collection using the remove() method and printed the updated vector.
