### Question:
LocalPermissioningConfiguration { public void setAccountAllowlist(final Collection<String> accountAllowlist) { if (accountAllowlist != null) { this.accountAllowlist.addAll(accountAllowlist); this.accountAllowlistEnabled = true; } }  List<EnodeURL> getNodeAllowlist(); static LocalPermissioningConfiguration createDefault(); void setEnodeDnsConfiguration(final EnodeDnsConfiguration enodeDnsConfiguration); void setNodeAllowlist(final Collection<EnodeURL> nodeAllowlist); EnodeDnsConfiguration getEnodeDnsConfiguration(); boolean isNodeAllowlistEnabled(); List<String> getAccountAllowlist(); void setAccountAllowlist(final Collection<String> accountAllowlist); boolean isAccountAllowlistEnabled(); String getNodePermissioningConfigFilePath(); void setNodePermissioningConfigFilePath(final String nodePermissioningConfigFilePath); String getAccountPermissioningConfigFilePath(); void setAccountPermissioningConfigFilePath(
      final String accountPermissioningConfigFilePath);  }### Answer:
@Test public void setAccountAllowlist() { final String[] accounts = {"1111111111111111", "2222222222222222", "ffffffffffffffff"}; final LocalPermissioningConfiguration configuration = LocalPermissioningConfiguration.createDefault(); configuration.setAccountAllowlist(Arrays.asList(accounts)); assertThat(configuration.getAccountAllowlist()).containsExactlyInAnyOrder(accounts); assertThat(configuration.isAccountAllowlistEnabled()).isTrue(); }
