Problem statement

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.

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("Hello World");

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


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


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

Vector elements : []


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.
