Previously in log4j 1.x I was able to to appender.setLayout() on and Appender but now in log4j 2.x there is no such method as setLayout(). How can I set a layout to an Appender object programmatically in log4j2 ?

Reconfigure Log4j Using ConfigurationBuilder with the Configurator. An alternative to a custom ConfigurationFactory is to configure with the Configurator . Once a Configuration object has been constructed, it can be passed to one of the Configurator. initialize methods to set up the Log4j configuration.
Layout class and overrides the format() method to structure the logging information according to a supplied pattern. PatternLayout is also a simple Layout object that provides the following-Bean Property which can be set using the configuration file: Sr.No.
Enumeration appenders = logger. getAllAppenders(); . . . fileBackupIndex = rollingFileAppender. getMaxBackupIndex();
Log4j2 RollingFileAppender is an OutputStreamAppender that writes log messages to files, following a configured triggering policy about when a rollover (backup) should occur. It also has a configured rollover strategy about how to rollover the file.
There is no setLayout() method. You will need to get the current Configuration and update it during runtime as explained in the documentation.
