// Java code to show the implementation of
// isEmpty 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("Clothes", 400);
        properties.put("Mobile", 5000);

        // Print Properties details
        System.out.println("Properties: "
                           + properties.toString());

        // Checking if the Properties is empty
        System.out.println("Is Properties empty: "
                           + properties.isEmpty());
    }
}
Output: 
Properties: {Book=500, Mobile=5000, Pen=10, Clothes=400}
Is Properties empty: false
Program 2: Java 
// Java program to demonstrate
// isEmpty() 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();

        // Print Properties details
        System.out.println("Current Properties: "
                           + properties.toString());

        // Checking if the Properties is empty
        System.out.println("Is Properties empty: "
                           + properties.isEmpty());
