java將70個字符進行分割

?// 測試字符串

?String source = "012345678a012345678b012345678c012345678d012345678e012345678f01234";

?// 規定長度

?int needLength = 10;

?// 優化的結果集。

?// 也可以直接 List<String> resultList = new ArrayList<String>();

?List<String> resultList = new ArrayList<String>(source.length()

?% needLength + 1);

?String subStr;

?int endIndex = 0;

?while (source.length() > 0) {

?// 判斷截取的長度

?endIndex = source.length() > needLength ? needLength : source

?.length();

?// 獲得街區後的長度

?subStr = source.substring(0, endIndex);

?// 截取剩余的字符串

?source = source.substring(endIndex);

?resultList.add(subStr);

?System.out.println(resultList);
