The elements() method of Properties class is used to get the enumeration of this Properties object. It can be further used to retrieve the elements sequentially using this Enumeration received.
Syntax:
public Enumeration elements()
Parameters: This method do not accepts any parameters.
Returns: This method returns an Enumeration of the values in this Properties object.
Below programs illustrate the elements() method:
Program 1:
Java
// Java program to demonstrate // elements() method. import java.util.*;
public class GFG {
// Main method
public static void main(String[] args)
{
// Create a properties and add some values
Properties properties = new Properties();
properties.put( "Pen" , 10 );
properties.put( "Book" , 500 );
properties.put( "Clothes" , 400 );
properties.put( "Mobile" , 5000 );
// Print Properties details
System.out.println( "Current Properties: "
+ properties.toString());
// Creating an empty enumeration to store
Enumeration enu = properties.elements();
System.out.println( "The enumeration of values are:" );
// Displaying the Enumeration
while (enu.hasMoreElements()) {
System.out.println(enu.nextElement());
}
}
} |
Output:
Current Properties: {Book=500, Mobile=5000, Pen=10, Clothes=400} The enumeration of values are: 500 5000 10 400
Program 2:
Java
// Java program to demonstrate // elements() method. import java.util.*;
public class GFG {
// Main method
public static void main(String[] args)
{
// Create a properties and add some values
Properties properties = new Properties();
properties.put( 1 , "100RS" );
properties.put( 2 , "500RS" );
properties.put( 3 , "1000RS" );
// print Properties details
System.out.println( "Current Properties: "
+ properties.toString());
// Creating an empty enumeration to store
Enumeration enu = properties.elements();
System.out.println( "The enumeration of values are:" );
// Displaying the Enumeration
while (enu.hasMoreElements()) {
System.out.println(enu.nextElement());
}
}
} |
Output:
Current Properties: {3=1000RS, 2=500RS, 1=100RS} The enumeration of values are: 1000RS 500RS 100RS
