The equals(value) method of Properties class is used to check for equality between two properties. It verifies whether the elements of one properties object passed as a parameter is equal to the elements of this properties or not. Syntax:
public boolean equals(Object value)
Parameters: This method accepts a parameter value of this Properties type and refers to the map whose equality is to be checked with this map. Returns: This method returns a boolean value stating if the equality holds for both the object Properties. Below programs illustrate the equals(value) method: Program 1: Java
// Java program to demonstrate
// equals(value) 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("Properties 1: "
                           + properties.toString());

        // Create another properties and add some values
        Properties properties1 = new Properties();
        properties1.put("Pen", 10);
        properties1.put("Book", 500);
        properties1.put("Clothes", 400);
        properties1.put("Mobile", 5000);

        // Print Properties details
        System.out.println("Properties 2: "
                           + properties1.toString());

        // Checking the equality
        System.out.println("Are both properties equal: "
                           + properties.equals(properties1));
    }
}
Output:
Properties 1: {Book=500, Mobile=5000, Pen=10, Clothes=400}
Properties 2: {Book=500, Mobile=5000, Pen=10, Clothes=400}
Are both properties equal: true
Program 2: Java
// Java program to demonstrate
// equals(value) 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());

        // Create another properties and add some values
        Properties properties1 = new Properties();
        properties1.put("Pen", 10);
        properties1.put("Book", 500);
        properties1.put("Clothes", 400);
        properties1.put("Mobile", 5000);

        // Print Properties details
        System.out.println("Properties 2: "
                           + properties1.toString());

        // Checking the equality
        System.out.println("Are both properties equal: "
                           + properties.equals(properties1));
    }
}
Output:
Current Properties: {3=1000RS, 2=500RS, 1=100RS}
Properties 2: {Book=500, Mobile=5000, Pen=10, Clothes=400}
Are both properties equal: false
