PropertyPermission Class hashCode() method

• hashCode() method is available in java.util package.
• hashCode() method is used to get the hash code value for this PropertyPermission object.
• hashCode() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
• hashCode() method does not throw an exception at the time of returning hash code.

Syntax:

    public int hashCode();

Parameter(s):

• It does not accept any parameter.

Return value:

The return type of the method is int, it retrieves the hash code value for this object.

Example:

// Java program to demonstrate the example 
// of int hashCode() method of 
// PropertyPermission

import java.util.*;

public class HashCodeOfPropertyPermission {
 public static void main(String arg[]) {
  // Instantiates two PropertyPermission object
  PropertyPermission prop_perm1 = new PropertyPermission("os.version", "write");
  PropertyPermission prop_perm2 = new PropertyPermission("os.name", "read");

  // By using hashCode() method is
  // to return the hash code of
  // PropertyPermission objects

  int hc1 = prop_perm1.hashCode();
  int hc2 = prop_perm2.hashCode();

  // Display hash code of prop_perm1
  System.out.print("prop_perm1.hashCode(): ");
  System.out.println(hc1);

  // Display hash code of prop_perm2
  System.out.print("prop_perm2.hashCode(): ");
  System.out.println(hc2);
 }
}

Output

prop_perm1.hashCode(): 1174476494
prop_perm2.hashCode(): -1228098475
