Vector toString() method in Java with Example

The java.util.Vector.toString() is an inbuilt method of Vector that is used to get a string representation of the objects of Vector in the form of a String representation of entries separated by “, “. So basically the toString() method is used to convert all the elements of Vector into String.

Syntax:

Vector.toString()

Parameter: The method does not take any parameters.



Return value: The method returns the String representation consisting of the string representation of the elements of the Vector.

Below programs illustrate the working of java.util.Vector.toString() method:

// Java code to illustrate the toString() method
  
import java.util.*;
  
public class GFG {
    public static void main(String[] args)
    {
  
        // creating vector type object
        Vector<String> vector = new Vector<String>();
  
        // Inserting elements into the table
        vector.add("Geeks");
        vector.add("4");
        vector.add("Geeks");
        vector.add("Welcomes");
        vector.add("You");
  
        // Displaying the Vector
        System.out.println("Vector: " + vector);
  
        // Displaying the string representaion
        System.out.println("The String representation is: "
                           + vector.toString());
    }
}

Output:

Vector: [Geeks, 4, Geeks, Welcomes, You]
The String representation is: [Geeks, 4, Geeks, Welcomes, You]

        Vector<Integer> vector

        vector.add(10);
        vector.add(15);
        vector.add(20);
        vector.add(25);
        vector.add(30);
  
        // Displaying the Vector
        System.out.println("Initial Vector is: " + vector);
  
        // Displaying the string representaion
        System.out.println("The String representation is: "
                           + vector.toString());
    }
}

Output:

Initial Vector is: [10, 15, 20, 25, 30]
The String representation is: [10, 15, 20, 25, 30]
