当list中放入的是一个数组的时候

public static void main(String[] args) {
        
        
        List list = new ArrayList();
        List list1 = new ArrayList();
        int[] a = {1,2,3,4,5,6,7,8};
        list.add(a);
    
        for (int i = 0; i < list.size(); i++) {
            int[] b = (int[]) list.get(i);
            System.out.print("打出数组的内容：————>");
            for (int j = 0; j < b.length; j++) {
                System.out.print(b[j]);
                list1.add(b[j]);
            }
            System.out.println("");
        }
        
        System.out.print("打出列表的内容：————>");
        for (int i = 0; i < list1.size(); i++) {
            System.out.print(list1.get(i));
        }
    }
