java.lang.IndexOutOfBoundsException：索引 16 超出长度 10 的范围错误

Question

I encountered the following error during the posting paging process. I don't even use an array, but I don't know why I get this error. How can I solve this?

BoardCriteria is an object that stores the information needed to page the bulletin list.

java.lang.IndexOutOfBoundsException: Index 16 out of bounds for length 10

    List<BoardTotalBean> boardList = service.getBoardListAll(club_no, cri);

Answer 1

It seems there is a limit of 10 in BoardCriteria:

public BoardCriteria() {
    this.page = 1;
    this.perPageNum = 10;
}

This might pose a problem when you attempt to access item 16:

List<BoardTotalBean> boardList = service.getBoardListAll(club_no, cri);
log.info("@@@@@@@@@@@@"+boardList.get(16)+"");
