Vector removeAllElements() method java

Let’s learn vector removeAllElements() method in java.

Vector removeAllElements() method in java

removeAllElements() method removes all components from this vector and sets its size to zero.

Syntax

public void removeAllElements()

Example

import java.util.*;

class VectorRemoveAllElementsDemo 
{
   public static void main(String[] args) 
   {
      Vector<Integer> v = new Vector<Integer>();
      v.add(4);
      v.add(6);  
      v.add(3);  
      v.add(5);  
      v.add(2);  
      System.out.println("Vector elements : " + v);  
      v.removeAllElements();
      System.out.println("Vector elements after removeAllElements() method : " + v);  
      System.out.println("Vector size after removeAllElements() method : " + v.size());  
   }
}

Output:

Vector elements : [4, 6, 3, 5, 2]
Vector elements after removeAllElements() method : []
Vector size after removeAllElements() method : 0

import java.util.*;

class VectorRemoveAllElementsDemo 
{
   public static void main(String[] args) 
   {
      Vector<String> v = new Vector<String>();
      v.add("h");
      v.add("e");
      v.add("l");
      v.add("l");
      v.add("o");
      v.add("w");
      v.add("o");
      v.add("r");
      v.add("l");
      v.add("d");  
      System.out.println("Vector elements : " + v);  
      v.removeAllElements();
      System.out.println("Vector elements after removeAllElements() method : " + v);  
      System.out.println("Vector size after removeAllElements() method : " + v.size());  
   }
}

Output:

Vector elements : [h, e, l, l, o, w, o, r, l, d]
Vector elements after removeAllElements() method : []
Vector size after removeAllElements() method : 0
