From source file:Main.java

public static void main(String[] args) throws IOException {
    FilePermission fp = new FilePermission("C://test.txt", "read");

    // the canonical string representation of the action
    String s = fp.getActions();/*  ww w . ja  v a2  s.com*/

    System.out.print("Action: " + s);

}

From source file:Main.java

}

From source file:Main.java
