What is the difference in execution time between System.out.print() and Log.info() methods?

Answer from AI

The method System.out.print() directly outputs data to the standard output stream (console), which usually happens quickly but can block the thread if the console is slow.

Log.info() is a call to a logger (for example, from the Log4j or SLF4J library), which is generally more time-consuming because it includes:

  • Message formatting
  • Log level checking
  • Writing to a file, database, or remote server

Therefore, Log.info() is usually slower than System.out.print(), especially with complex logging configurations. In production, it is recommended to use loggers with proper level configurations to avoid unnecessary logging overhead.
