我尝试使用java prepared语句从excel文件中读取。我是java的新手。我必须从excel文件中获取数据，并相应地在一些处理中填充mysql中的四个表。我的代码如下。没有抛出异常，但在读取第一行后，它会截断while循环
try{
String line;
BufferedReader br=new BufferedReader(new FileReader(filePath));
String reg="NOTHING",sub="NOTHING";
String data[]=null;
PreparedStatement pst=null;
int line_Cnt=0;
while((line=br.readLine())!=null)
{
//chekcing and terminating first line headers
if(line_Cnt==0)
{
line_Cnt=1;
continue;
}
//checking for an empty line
data=line.split(",");
if(data[9].toString().equals("Grand Total"))
{
sub="NOTHING";
try{
qry="insert into tbl_report(studReg,grandGrade,grandObtained,grandMax,creditsAwarded,gradeAverage) values(?,?,?,?,?,?)";
pst=cn.prepareStatement(qry);
pst.setString(1,data[6].toString());
pst.setString(2,data[12].toString());
pst.setInt(3,Integer.parseInt(data[13].toString()));
pst.setInt(4,Integer.parseInt(data[14].toString()));
pst.setInt(5,0);
pst.setFloat(6,0.0f);
pst.executeUpdate();
}
catch(Exception e)
{System.out.println(e.getMessage());}
}
else if(data[9].toString().equals("Credits Awarded")){
qry="update tbl_report set creditsAwarded=? where studeReg=?";
pst=cn.prepareStatement(qry);
pst.setInt(1,Integer.parseInt(data[14].toString()));
pst.setString(2,data[6].toString());
pst.executeUpdate();
}
else if(data[9].toString().equals("Grade Point Average"))
{

pst.setString(2,data[6].toString());
pst.executeUpdate();

}
else{

请有人帮助我.....
