java - 线程中的异常 "main"java.lang.ArrayIndexOutOfBoundsException : 101

Question

我试图查看数组的内容，但是当我运行时出现错误消息

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 101

有谁知道问题出在哪里吗？这是我的代码:

public final class KonversiQtoH extends DebitDiberikan{

public KonversiQtoH() throws SQLException{
    QBeriPintu1();
}
Connection c = KoneksiDatabase.getKoneksi();
Float[] fine;
public void QBeriPintu1() throws SQLException{
    try{
        List rowValues = new ArrayList();
        Statement s = c.createStatement();
        String sql = "SELECT LA40 from tabel_debit";
        ResultSet rs = s.executeQuery(sql);
        while (rs.next()){
            rowValues.add(rs.getFloat("LA40"));
        }
        rs.close();
        s.close();
        fine = (Float[]) rowValues.toArray(new Float[rowValues.size()]);
    }catch(SQLException e){
        System.err.println("QKanan, error");
    }
}
public static void main(String[] args) throws SQLException{
    KonversiQtoH j = new KonversiQtoH();
    j.QBeriPintu1();
    for (int i=0; i<=j.fine.length; i++){
        int a = i+1;
        System.out.println(a+". "+j.fine[i]);
    }
}
}

以下行会产生错误:

for (int i=0; i<=j.fine.length; i++) {

替换为:

for (int i=0; i<j.fine.length; i++) {
