I have added comments to my post. If you still don't understand, you need to put some effort in learning the basics.

Well, you didn't get the answer. I hate to state the obvious; the script is checking each daemon and starting which ever is down. If 3 are running and 2 are down, it will start only those two. Why don't you bring down couple of daemons and try running it?

U can try this

====================================================
#!/bin/ksh
i=1
while [ $i -le 5 ];do

proc=java$i
JAVA=`ps -aef |grep -v grep| grep -c $proc`
if [ $JAVA == 1 ]
then
echo " $proc already running"
else
/test/java/scripts/daemons/startjava$i
fi
i=$(( $i + 1 ))
done
