how to remove all elements from vector in java?


The java.util.Vector class implements a growable array of objects. Like an array, it contains components that can be accessed using an integer index. However, the size of a Vector can grow or shrink as needed to accommodate adding and removing items after the Vector has been created. It extends AbstractList and implements List interfaces.

The clear() method is used to delete or remove all elements of a vector at one call in java.

Example:

package com.codesjava;
 
import java.util.Vector;
 
public class Test {
  public static void main(String args[]){
	Vector<String> vector = new Vector<String>();
        //adding elements to the end
	vector.add("Jai");
	vector.add("Mahesh");
	vector.add("Hemant");
	vector.add("Vishal");
	System.out.println("Actual vector:"+vector);
	vector.clear();
        System.out.println("After clear vector:"+vector);
  }
}

Output

Actual vector:[Jai, Mahesh, Hemant, Vishal]
After clear vector:[]
