How do i use an if statement to check if a method has been called?

I'm trying to make a timer run so I can't constantly shoot, but then if I don't shoot for a long time, I still have to wait for the timer as it resets when it's done, not when I shoot. How would I make an if statement to check if my "fire" method has been called?

Do you mean this: 
if (timer != 0)

Well, My bullet fires repeatedly, but with a short recharge. Is there a way to make the recharge only reset when the method is called?

"method"? What method? Where called from?

Only reset it in the fire method.

It didn't work. This is the code: 
private void fire()
     {
         Bomb bomb = new Bomb();
         
         if (Greenfoot.isKeyDown("space"))
         getWorld().addObject(bomb, getX(), getY());
         bomb.setRotation(getRotation());
         timer = 15;
     }

You are missing brackets for your if block.

Also, you are creating a bomb every time the method is called -- unnecessarily. Create the bomb inside the if block. Where are you regulating creation of bombs based on the timer (if (timer == 0)?

Just realised I had no brackets in my If statement... Whoops.
