Replace Parameter with Explicit Methods

Replace Parameter with Explicit Methods

You have a method that runs different code depending on the values of an enumerated parameter.

Create a separate method for each value of the parameter.

        void setValue (String name, int value) {
                if (name.equals("height")) {
                        _height = value;
                        return;
                }
                if (name.equals("width")) {
                        _width = value;
                        return;
                }
                Assert.shouldNeverReachHere();
        }


        void setHeight(int arg) {
                _height = arg;
        }
        void setWidth (int arg) {
                _width = arg;
        }
