This will put all alerts and command outout in same file
Code:
 
ps -eo pid,pcpu,args | sort +1n | grep -i java | nawk -v threshold=<VALUE> '$2 > threshold {print $1,"has crossed the threshold value of cpu";} $2 <= threshold {print;}' > outputFile

If you need it in different files then
All alerts in one file
Code:
ps -eo pid,pcpu,args | sort +1n | grep -i java | nawk -v threshold=<VALUE> '$2 > threshold {print $1,"has crossed the threshold value of cpu";}' > alertFile

Rest in another file
Code:
ps -eo pid,pcpu,args | sort +1n | grep -i java | nawk -v threshold=<VALUE> '$2 <= threshold {print;}' > outputFile

And content of alertFile can be sent as email using mailx command.
Something like (verify mailx path):
Code:
/usr/sbin/mailx -s "Your Subject" ADDRESS_EMAIL < alertFile
