I am just curious to know, what happens when System.out.print() is called in a servlet?
Where does it write the text?
Or is there any significant use of System.out in a servlet?

out. println does not print to the console, it prints to the standard output stream ( System. out is Java's name of the standard output stream). The standard output stream is usually the console, but it doesn't have to be.
out. println() Since the System object is part of the core Java objects, it can be used everywhere without the need to install any extra classes. This includes Servlets, JSP, RMI, EJB's, ordinary Beans and classes, and standalone applications.
out. printlns will start showing up in the catalina. out file. If you start tomcat with Catalina.sh run from a command line you will see the prints in the output.
How in Servlets, out. println writes the html text to container's response object where normally in System.
It depends on your servlet container.
For Tomcat :
When running Tomcat on unixes, the console output is usually redirected to the file named catalina.out. The name is configurable using an environment variable. (See the startup scripts). Whatever is written to System.err/out will be caught into that file.
For jetty, you can redirect standard output to a file :
It is possible to redirect all output sent to stderr and stdout to a file that can be rolled over [...]

System.out.print() writes on Server Console.
