permission = new PropertyPermission(“java.*", “read,write");
// Check permissions
checkFileReadPermission(“java.changfa");
checkFileWritePermission(“java.changfa");
}

private static void checkFileReadPermission(String path) {
// Check permission on read action
if(permission.implies(new PropertyPermission(path, “read"))) {
System.out.println(“Has permissions on “+path+" 読込み権限");
}
}

private static void checkFileWritePermission(String path) {

if(permission.implies(new PropertyPermission(path, “write"))) {
System.out.println(“Has permissions on “+path+" 書込み権限");
}
}
