You’re in luck, the Not Equals Operator != works the same with Booleans.

Boolean firstBoolean = true;
Boolean secondBoolean = true;
Boolean resultBoolean = firstBoolean != secondBoolean; 
// resultBoolean becomes FALSE, because they are the same

Boolean thirdBoolean = true;
Boolean fourthBoolean = false; //false this time 
Boolean resultBoolean2 = thirdBoolean != fourthBoolean; 
// resultBoolean2 becomes TRUE, because they are different

We can use this operator on the Boolean keywords themselves:

Boolean firstBoolean = true;
Boolean resultBoolean = firstBoolean != true; 
// resultBoolean becomes FALSE

Oh, but there’s a twist. There’s always a twist. With Booleans, we can use the ! operator (you can call this the not operator) by itself to negate a Boolean value. By negation here, we mean reversing the truth of a statement.

! turns a true statement false, and turns a false statement true. When we use it with a variable like so:

Boolean firstBoolean = !true; 
// Is the same as saying: 
Boolean firstBoolean = false; 

You can read this as “not true” - if something is “not true” it’s false. If something is “not false” it’s true:

Boolean tcvMatch = true;
tcvMatch = !tcvMatch; //“not true” is false
// tcvMatch is now false
tcvMatch = !tcvMatch; // “not false” is true
// tcvMatch is now true
