Your Input class is unneeded.

I was watching your tutorial and noticed that you created the Input class witch is largely unneeded. You can do the same thing it does more efficiently with

while (Keyboard.next()) {
    char key = Keyboard.getEventCharacter();
    boolean state = Keyboard.getEventKeyState(); // If the key is held down (true) or released (false)
   // TODO: Handle key clicks
}

Another thing to look into is using

int NUM_KEYCODES = Keyboard.getKeyCount();

instead of the current constant.

Actually, in his case, the Input class is needed. Since there are multiple components potentially retrieving input, Keyboard.next() will not suffice - the first Component.input() called that uses a while (Keyboard.next()) loop will hog all of the events, and none of the other components will be able to read them (unless they happen between the input() calls.
However, his Input class can be optimized using Keyboard.next() instead of checking every key indiviudally for its state.

Sorry, I was more referring to the loop covering all of the keys. Iterating over every key is unneeded.

I agree. If he had used Keyboard.next() instead it could potentially run faster.
