# Class NetPermission

java.lang.Object
java.security.Permission
java.security.BasicPermission
java.net.NetPermission

All Implemented Interfaces:
  `Serializable, Guard`

@Deprecated(since="25", forRemoval=true) public final class NetPermission extends BasicPermission
Deprecated, for removal: This API element is subject to removal in a future version.
This permission cannot be used for controlling access to resources as the Security Manager is no longer supported.
This class is for various network permissions. A NetPermission contains a name (also referred to as a "target name") but no actions list; you either have the named permission or you don't.

The target name is the name of the network permission. The naming convention follows the hierarchical property naming convention, typically the reverse domain name notation, to avoid name clashes. An asterisk may appear at the end of the name, following a ".", or by itself, to signify a wildcard match. For example: "foo.*" and "*" signify a wildcard match, while "*foo" and "a*b" do not.

  1.2
