The hashCode() method of Properties class is used to generate a hashCode for the given Properties containing key and values.
Syntax:
Java
Java
public int hashCode()Parameters: This method has no argument. Returns: This method returns the hashCode value for the given map. Below programs show the implementation of int hashCode() method. Program 1:
// Java code to show the implementation of
// hashCode 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: "
+ properties.toString());
// Getting the hashCode value
System.out.println("HashCode: "
+ properties.hashCode());
}
}
// Java code to show the implementation of// hashCode methodimport 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: " + properties.toString()); // Getting the hashCode value System.out.println("HashCode: " + properties.hashCode()); }}
Output:
Program 2:
Properties: {Book=500, Mobile=5000, Pen=10, Clothes=400}
HashCode: 548388082
// Java program to demonstrate
// hashCode() 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());
// Getting the hashCode value
System.out.println("HashCode: "
+ properties.hashCode());
}
}
