I am new to the Cron Job, I am trying to schedule a Java program that print current Date on System.out every 5 minutes. I put inside the command line
is "java printBeep"
But the output I get from email is

Please tell me where I went wrong, btw the interface only permits 1 line of command to input, and I can't seem to put more lines of command lines.
Please help if can, thank you all.
Have a nice day!

use the complete path to the java file e.g. /usr/bin/java. I think
the cron job doesnt uses PATH variables, so you have to define the
absolute path

Or you can put whatever commands you like in a script file, and execute that from your "cron".

By the way, there is no System.out from within the cron job, as there is no terminal associated with the cron job.
Depending on how your cron environment is set up, you may get an email sent to you with the output that would have appeared on the screen if there had been a screen.
