total percentage of memory use for all processes with a given name

ps -eo pmem,comm | grep java | awk '{sum+=$1} END {print sum " % of RAM"}'
This command will add up RAM usage of all processes whose name contains "java" and output the sum of percentages in HRF. Also, unlike the original #15430, it wont fail on processes with a usage of >9.9%. Pleases note that this command wont work reliably in use cases where a significant portion of processes involved are using less than 0.1% of RAM, because they will be counted as "0", even though a great number of them could add up to significant amounts.
Sample Output
43.5 % of RAM
