unequal strings

I want to know how to check if 2 strings are unequal. I know that if you want to check if user_input is equal to "show" then you would douser_input.equals("show") but how do you check the opposite?

# 1

if(user_input.equals("show") == false) {

// ...

}

which is the same as:

if(!user_input.equals("show")) {

// ...

}
