    FilePermission fp1 = new FilePermission("C://test.txt", "write");
    FilePermission fp2 = new FilePermission("C://test1.txt", "read");
    FilePermission fp3 = new FilePermission("C://test.txt", "read");

    // tests if implied by this object
    boolean bool = fp.implies(fp1);

    // print
    System.out.println(bool);

    bool = fp.implies(fp2);
    System.out.println(bool);

    bool = fp.implies(fp3);
    System.out.print(bool);

  }
}
