主程序无法识别我的类方法java

我之前问过一个问题，但我没能解决。我试图创建一个

补遗

（类）数组，并将其存储在

杂志

（类）的单个对象中。尝试调用我的

fillArray

方法时，出现错误：

cannot find symbol: 
symbol: method fillArray(Supplement[])
location: javaapplication1

这有什么问题吗

主程序：

package javaapplication1;

public class JavaApplication1 {
    public static void main(String[] args) {


        Supplement[] supplements = new Supplement[4];

        fillArray(supplements);

        Magazine magazineobj = new Magazine("The Wheels Special", 35, supplements);
        magazineobj.printMagazine();

    }

}

您需要使方法

fillArray

static

在没有

Supplement

实例的情况下访问它，因为在

JavaApplication1

类中没有名为

fillArray

的方法是

static

或者可以通过静态上下文访问

使用：

publicstaticvoidfillarray（增补[]增补）{…}

电话：

Supplement.fillArray（supplements）；

您想做什么？在这里，您可以从静态上下文调用实例方法。。。它不能工作你应该使这个方法

静态
并这样调用它：
Supplement.fillArray（supplements）这似乎让我现在可以编译了。但是，没有打印出来。我在杂志上的印刷方法有什么问题吗？这似乎让我现在可以编译了。但是，没有打印出来。我在杂志中的打印方法是否有问题？这是因为
magazineobj
实例中的
magazineobj
字段为空。此外，您不会覆盖
toString
方法。您可以在
main
-方法中尝试
System.out.println（magazineobj）
，但如果不覆盖
toString（）
，则只会打印对象的名称和内存地址。
