The book says the parameter int x is ignored. So x = 4. Why doesn't it use the input, 10?

Because on line 6, a new value of 4 is assigned to it. Line 7 will use the new value of 4, not the value of 10 that was initially passed in. You can declare the parameter x as final to avoid things like this, or just don't assign new values to x in the body of the method/constructor.
