I’m trying to write a program which draws an `I` if no keys are pressed, and an `E`or an `F`if those keys  
are pressed. Use straight lines to draw these letters. The window size is (120,120).

very good idea,  
show us your code ( in \</\> formatter )  
and detail description of problems or questions.

Ok, ‘challenge’ accepted, Java right?  
(You know that theres text() and no need to draw with lines right?)

  else{

    line(width/2 ,20,width/2 ,height - 20);
    line(width/2 - 20,height - 20,width/2 + 20,height - 20);
  }
  
}

```

Remember to caps lock bc `key` is case sensitive

</div>

for the code, if no keys are pressed the program draws an I, but when I press E or F, it draws neither of those letters

use caps lock, i made it that if you press uppercase E and uppercase F, but you can add  
if(key == ‘E’ || key == ‘e’){}, so it works for lowercase too
