If without else not running

I have a little code for testing a sprite, that I want to move with the mouse. When I click the screen, the sprite has to move to the clicked point. But something weird is going on.

I'm running it in a thread, called Controls, that extends to Thread and implements MouseListener, and using the following code, the sprite moves.

public void run() {
    while(true){
        if((int)point.getX() > player.getX()){
            while((int)point.getX() > player.getX()){
                player.moveX(1);
            }
        }
        else{
            System.out.println("Nah!");
        }
    }
}

Everything works as expected, but if i do this:

public void run() {
    while(true){
        if((int)point.getX() > player.getX()){
            while((int)point.getX() > player.getX()){
                player.moveX(1);
            }
        }
    }
}

It doesn't work. If i do this:

public void run() {
    while(true){
        if((int)point.getX() > player.getX()){
            while((int)point.getX() > player.getX()){
                player.moveX(1);
            }
        }
        else{

        }
    }
}

It doesn't work either. I have no idea of what is going on, any ideas?
