| Method | Description |
|---|---|
| equals(object obj) | It checks whether the two SocketPermission objects are equal or not. |
| getActions() | It returns the actions of this SocketPermission object in String format |
| hashcode() | It returns the hash code value for this object. |

Example:
Java
// Java Program to show the usage of// java.net.SocketPermission Classimport java.io.IOException;import java.net.SocketPermission;import java.security.Permission;import java.security.PermissionCollection;public class Socket { public static void main(String args[]) { try { // getting permission object Permission p = getPermission(); // print actions of permission p System.out.println(p.getActions()); // printing hashcode value of permission p System.out.println(p.hashCode()); // creating a permissionCollection object and // printing it PermissionCollection p1 = p.newPermissionCollection(); System.out.print(p1); } catch (Exception e) { System.err.print("Permission denied"); } } public static Permission getPermission() throws IOException { int port = 3000; String host = "localhost"; return new SocketPermission(host + ":" + port, "Connect,resolve"); }} |
