Boolean in Mutator Method

Question

I have a project in which I'm working on a class that has mutator and accessor methods. For my mutator methods, I have to return a boolean. "True - indicating the height is within range and that the Object's value has been modified." False, obviously, if it isn't. Height being in range means it's between 1-10 inclusive.

I know how to write a boolean, but how would I do that inside a mutator method? Usually, and keep in mind I'm very new, I would write something along the following:

public void setHeight(int newHeight){
    height = newHeight;
}

How would I place my boolean inside of the mutator method, as well as ensure that the height is within its proper range? My boolean would be something along the lines of:

if (height >= 1 && height <= 10) {
    System.out.println("It's perfect!");
} else {
    System.out.println("Not right!");
}

You'll have to change the return type of your setter:

public boolean setHeight(int newHeight) {
    if (1<=height && height<=10) {
        height = newHeight;
        return true;
    } else {
        return false;
    }
}
