Run and kill java program in background in Linux

Question

i have a little java program that i want to run in background (i don't want to block the cli). I want also have the possibility to kill it (without looking manually for the PID). I want to create to script: ./start.sh -> starts the java program in background ./stop.sh -> try to kill the java program (running in background).

Any ideas ?

kill $(cat /var/run/javaProgram.pid)
