在java中访问父类中的子常量

class ParentClass {
    public static final int CONSTANT = 10;
}

class ChildClass extends ParentClass {
    public static final int CONSTANT = 20;
}

public class Main {
    public static void main(String[] args) {
        System.out.println(ChildClass.CONSTANT); // 输出 20
    }
}

class ParentClass {
    public static final int CONSTANT = 10;
    
    public static int getConstant() {
        return CONSTANT;
    }
}

class ChildClass extends ParentClass {
}

public class Main {
    public static void main(String[] args) {
        System.out.println(ChildClass.getConstant()); // 输出 10
    }
}
