java – 重写超类的受保护方法

如果我错了,每当子类(BClass)覆盖超类(AClass)的受保护方法(即initClass())时,请纠正我.如果您实例化子类.超类必须使用子类指定的overriden方法.

public class Example {

    public class AClass {

        private String a;

        public AClass() {
            initClass();
        }

        protected void initClass() {
            a = "randomtext";
        }
    }

    public class BClass extends AClass {

        private String b = null; 
        private String c;          


        @Override
        protected void initClass() {
            b = "omg!";
            c = "gg";
        }

        public void bValue() {
            System.out.println(b);   // prints null
            System.out.println(c);  // prints "gg"
        }
    }

    public static void main(String[] args) {
        Example.BClass b = new Example().new BClass();
        b.bValue();

    }

}
