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 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 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
