Example

The following example shows the usage of java.util.Vector.removeRange() method.

package com.tutorialspoint;

import java.util.Vector;

public class VectorDemo {
   public static void main(String[] args) {

      // create an empty Vector vec with an initial capacity of 7      
      Vector<Integer> vec = new Vector<Integer>(7);

      // use add() method to add elements in the vector
      vec.add(1); 
      vec.add(2);
      vec.add(3);
      vec.add(4);
      vec.add(5);
      vec.add(6);
      vec.add(7);

      /**
      * Removing range of elements is not directly supported. However, it
      * can be done by using subList and clear methods.
      */
      System.out.println("Remove elements from 2nd to 4th");
      vec.subList(2,4).clear();

      // let us print all the elements available in vector
      System.out.println("Numbers after removal :- "); 
      
      for (Integer number : vec) {         
         System.out.println("Number = " + number);
      }           
   }    
} 

Let us compile and run the above program, this will produce the following result.

Remove elements from 2nd to 4th
Numbers after removal :- 
Number = 1
Number = 2
Number = 5
Number = 6
Number = 7
