Print a Vector in a comma-delimited list, in index order and surrounded by square brackets ([]) in Java

A Vector can be printed in a comma-delimited list, in index order and surrounded by square brackets ([]) by simply using System.out.println() along with the Vector object.

A program that demonstrates this is given as follows −

Example

import java.util.Vector;
public class Demo {
   public static void main(String args[]) {
      Vector vec = new Vector(5);
      vec.add(4);
      vec.add(1);
      vec.add(3);
      vec.add(9);
      vec.add(6);
      System.out.println(vec);
   }
}

The output of the above program is as follows −

[4, 1, 3, 9, 6]

Now let us understand the above program.

The Vector is created. Then Vector.add() is used to add the elements to the Vector. Finally, the Vector elements are printed in a comma-delimited list, in index order and surrounded by square brackets ([]). A code snippet which demonstrates this is as follows −

Vector vec = new Vector(5);
vec.add(4);
vec.add(1);
vec.add(3);
vec.add(9);
vec.add(6);
System.out.println(vec);
