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:
Program 1:
// 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 representation
System.out.println( "The String representation is: "
+ vector.toString());
}
} |
Vector: [Geeks, 4, Geeks, Welcomes, You] The String representation is: [Geeks, 4, Geeks, Welcomes, You]
Program 2:
// Java code to illustrate the toString() method import java.util.*;
public class GFG {
public static void main(String[] args)
{
// Creating an empty Vector
Vector<Integer> vector
= new Vector<Integer>();
// Inserting elements into the table
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 representation
System.out.println( "The String representation is: "
+ vector.toString());
}
} |
Initial Vector is: [10, 15, 20, 25, 30] The String representation is: [10, 15, 20, 25, 30]
