What does this mean?(Related to if statements)

Question

if(!(a>b)){
//some code for output
}
What does that exclamatory mark mean?

Edit0:I got the meaning but I have one question can't we just write b>a instead of this.

Edit1:Thanks to Sean And Abdul for the answer.

Answer 1

Same as
if (a<=b)

Answer 2

No, (b > a) isn't the same thing, but you could write (b >= a).

Answer 3

It means "not". Basically, it's checking if a is not greater than b.

Answer 4

Can't we just write b>a instead of this?

Answer 5

Thanks

Answer 6

@Abdul It's checking if a is not greater than b. For the if statement to work, b has to be greater than or equal to a. If a is equal to b, then it still fulfills the condition.

Answer 7

@Abdul ...Hang on, let me clarify.

Let's say a = 5 and b = 7. Thus, we can replace them like this:

if (!(5 > 7)) = true

Now let's say a = 5 and b = 5.

if (!(5 > 5)) = true

So the if condition still works if a and b are equal, so it's the same as:

if (b >= a)
