PropertyPermission Class implies() method

  • implies() method is available in java.util package.
  • implies() method is used to check whether this PropertyPermission implies the given permission (perm) or not.
  • implies() 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.
  • implies() method does not throw an exception at the time of check implicate the given permission.

Syntax:

    public boolean implies(Permission perm);

Parameter(s):

  • Permission perm – represents the permission object to be tested.

Return value:

The return type of the method is boolean, it returns true when this object implies the given permission otherwise it returns false.

Example:

// Java program to demonstrate the example 
// of boolean implies(Permission perm) method of 
// PropertyPermission

import java.util.*;

public class ImpliesOfPropertyPermission {
 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 implies() method isto
  // check whether this PropertyPermission
  // holds the given permission or not
  boolean status1 = prop_perm1.implies(prop_perm1);
  boolean status2 = prop_perm2.implies(prop_perm1);

  // Display prop_perm1 status
  System.out.print("prop_perm1.implies(prop_perm1): ");
  System.out.println(status1);

  // Display prop_perm2 status
  System.out.print("prop_perm2.implies(prop_perm1): ");
  System.out.println(status2);

Output

prop_perm1.implies(prop_perm1): true
prop_perm2.implies(prop_perm1): false
