Help with knowing if .split()[1] exists

[trath]

I want to do that if somebody types "!say ABC" then it would be able to acess only "ABC" and do whatever to it.
so I have an

str.indexOf("!say")

, then to get "ABC" I do

str.split(" ")[1]

The problem is that if somebody types only "!say" with nothing that follows, the program crashes due to "out of bounds" or w/e. (because I am trying to access "str.split(" ")[1]" which doesn't exist).
What if statement can I use to check if ".split(" ")[1]" exists?


Thanks

String[] split = str.split(" ");
if(split.length > 1) {
   // split[1] exists
}
