java - 如何将引用数组传递给setter？

Question

编写一个名为 setTo5 的方法，该方法传递对整数数组的引用，并将该数组的内容设置为全 5。这是我到目前为止所拥有的，它在 public static void main(...); 之后的第二行给了我一个错误。如何成为更好的二传手？

public class Set5 {
    private static int n = 8;
    static int[] boop = new int[n];

    public static void main(String[] args){
        int[] roop = new int[n];
        roop.setTo5(5);

    }

    public void setTo5(int poop){
        for(int i = 0; i<n ; i++){
        poop = boop[i];

        }
    }

}

尝试这样的事情:

public class Set5 {
    private static int n = 8;
    static int[] boop = new int[n];

    public static void main(String[] args){
        int[] roop = new int[n];  

        //Create instance of Set5 class  to call setter
        Set5 set5reference = new Set5(); 

        set5reference.setTo5(roop);

        //All the values in roop will now be 5 as set by setter.

    }

    //change this method to accept array reference like this
    public void setTo5(int[] poop){
        for(int i = 0; i<n ; i++){
            poop[i] = 5;
        }
    }
}
