数组越界,数组只有2个元素,也就意味着只能用 0 和 1 取值,但你程序给的是2.com.test.chuchai.StoreData.duobiao(StoreData.java:76)
这行代码前后检查下
String sql0="select z_dl from dbxx where dbh='"+list0.get(i)+"'and yhh='"+it.getYhh()+"'";
PreparedStatement pstm0=cm2.prepareStatement(sql0);
ResultSet rs0=pstm0.executeQuery();
while(rs0.next()){
DianL dl=new DianL();
dl.setZ_dl(rs0.getFloat("z_dl"));
list1.add(dl);
}
}
这段去掉就没错了 敢问 这哪错了啊
提示很明确,是数组越界异常,请参照代码StoreData.java的76行,
楼主以前没玩过List吧?List的get(序号)是从 0 ~ size()-1
