Check if RadioButton is NOT selected

I have this logic in my code

if(r40.isChecked()){ //do this }

It works great, but I needed the negative, "if rb.isNotChecked" or ".isChecked() = false"

But I cant see to find it, also I can't use the RadioGroup because all my RadioButtons are not inside one, I'm controlling them manually

I mean you COULD do
if(r40.isChecked() == false){ //do something }
BUT
if(!r40.isChecked){ //do something }
Is much better/cleaner

Try this: 

if (! r40.isChecked()) {    

       //Do something 
}

In more detail the exclamation mark added in this code reverses the following code in the same block, causing the code to mean:

if (r40.isNotChecked()) {

       //Do something
}

I hope this helped!

Try with negative check 

if(!r40.isChecked()){
     //do this
 }

this check if radio isn`t checked.
