数组与List之间互转

1.1. 数组转List

 

List data = new ArrayList();

            for (int k = 2; k < sheet.getRows(); k++) {

                Cell[] row = sheet.getRow(k);

                data = Arrays.asList(row);  // 数组转List

            }

 

1.2. List转数组

 

    String[] arr = (String[]) list.toArray(new String[size]);
