"Too small maximum heap" Java error in Manjaro Linux running through terminal

Really don't know what to do about this one. I'm trying to start a minecraft server with more RAM but the commands in the terminal give me this error. The server works only if I go to the file manager and click on the server.jar file, it then boots up like normal with the GUI and everything. The problem is that I can't set RAM parameters through there, only through commands. I've tried: `sudo java -Xmx1024 -Xms1024 -jar server.jar` `sudo java -Xmx4096 -Xms1024 -jar server.jar` `sudo java -Xmx8164 -Xms1024 -jar server.jar` `sudo java -Xmx1000000 -Xms1024 -jar server.jar` `sudo java -Xmx3072 -Xms2048 -jar server.jar` `sudo java -Xmx2048 -Xms512 -jar server.jar` `sudo java -Xmx1024 -Xms512 -jar server.jar` `sudo java -Xmx512 -Xms256 -jar server.jar` All result in the exact same error every time: "Error occurred during initialization of VM" "Too small maximum heap" I've tried these with -nogui too, same error.
