Java program to remove all elements of Vector collection using removeAllElements() method

Given a Vector collection, we have to remove all elements of it using removeAllElements() method.
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 all elements of the Vector collection using the removeAllElements() method.

Program/Source Code:

The source code to remove all elements of Vector collection using the removeAllElements() method is given below. The given program is compiled and executed successfully.

// Java program to remove all elements of Vector collection 
// using the removeAllElements() 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("Vector elements: " + vec);

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

Output:

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

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 removeAllElements() method to remove elements from vector vec and set its size to zero.
