I have some values in List<SelectItem> selectedDividendYears
Now I want to make a string concatenating all the values of this list as csv.
< 强度 > 示例 :
selectedDividendYears = { 123 , sdf234 , 12 1234c }
现在我只想要一个字符串, 它会看起来像...
"123, sdf, 12 1234c"
Apache 公有语言,StringUtils.join.(选定的Dividid years, ) ; 。
StringBuilder str = new StringBuilder();
boolean first = true;
for (SelectItem item : selectedDividendYears) {
if (first) first = false;
else str.append(",");
str.append(item.toString());
}
String outputString = str.toString();
