Arduino compilling error with java

Projects Programming
1

Hellot everybody!
when I used this code:

const int LED=9;
const int BUTTON=2;

void setup() {
  pinMode (LED, OUTPUT);
  pinMode (BUTTON, INPUT);

}

void loop() {
  if (digitalRead(BUTTON) == LOW); 
  {
    digitalWrite(LED, LOW);
  }
  else {
    digitalWrite(LED, HIGH);
    }

}

the arduino IDE displayed me an error:

AND YET IT DISPLAYING BACKGROUND COLOR RED ON A FIRSTEST LINE OF CODE

doubt the above is the cause of java error, but the semicolon, ";" should be removed because it becomes the body of the if statement and results in an "else" without matching "if"

Why are you running a nightly build? They are test versions of software and might or might not work as expected.

Does the same oroblem show when you try to upload e.g. blink? If yes, I suspect that you have a corrupt installation.

Are you using the web based ide ?
