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.
