Submitted by Nidhi, on May 20, 2022

Problem Solution:

In this program, we will create a Vector collection with a different types of elements. Then we will remove all elements of vector collection using the clear() method.

Program/Source Code:

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

// Java program to remove all elements of 
// 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);
    vec.add("Hello World");

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

    vec.clear();

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

Output:

Vector elements : [10, 20.5, true, Hello World]

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 and add elements to it. Then we removed all elements from the vector using the clear() method and printed the updated vector collection.
