title: Deviding strings and integers of user input
body: <p>I'm new to coding. I want to try out a few things using java with eclipse. In this programm the user should be able to use a few commands. For example a command called "add".
  So when the user is typing "add 15 -200" the programm should call the add method and give it those to parameters. Sadly I have no idea how to properly read the integers and give them the "add" method. I just don't see how to devide the "add" string from the integers. Please help! Thanks in advance! 
  Take care</p>
