Unreachable statement

I'm getting this error and I can't solve it :( I still don't see anything wrong in my code. Can someone help me?

Picked up JAVA_TOOL_OPTIONS: -Xmx128m
Picked up _JAVA_OPTIONS: -Xmx128m
./Game.java:23: error: unreachable statement
boolean isHit = answer.indexOf(letter) != -1;
^
1 error

public boolean applyGuess(char letter){ if (misses.indexOf(letter) != -1 || hits.indexOf(letter) != -1);{ throw new IllegalArgumentException(letter + " has already been guessed"); }

boolean isHit = answer.indexOf(letter) != -1;
if (isHit){
  hits += letter;
} else {
  misses += letter;
}
return isHit;

}

You have placed a semicolon after your if statement declaration:

if (misses.indexOf(letter) != -1 || hits.indexOf(letter) != -1);

if statements should not have semicolons added. The semicolon tells Java that you are done with your if statement, which means that it treats the next block of code (which is supposed to be a part of the if statement) as regular code that should always run. Which means that your code will always throw an exception.

Once an exception is thrown the method stops executing, which means that the code below it is indeed unreachable. If you simply remove that semicolon that error should go away.
