【问题描述】：

我做了一个铁路管理系统项目，想将文本字段和 Java 表中的值插入 MySQL 数据库。我怎样才能摆脱这个错误？请帮忙！！

int rows = jTable1.getRowCount();
for(int row = 0; row<rows ; row++){
    int index=1;
    String S_No = (String) jTable1.getValueAt(row, 1);
    String Name = (String) jTable1.getValueAt(row, 2);
    String Age = (String) jTable1.getValueAt(row, 3);
    String Gender = (String) jTable1.getValueAt(row, 4);
    String berth_preference = (String) jTable1.getValueAt(row, 5);
    String Quota = (String) jTable1.getValueAt(row, 6);
    String tno =(String) cb1.getSelectedItem();
    String tname =(String) cb2.getSelectedItem();
    String clas =(String) cb3.getSelectedItem();
    String tic= tick.getText();
    String frms=frm.getText();
    String tos=to.getText();
    String boarding=bp.getText();
    String reser=ru.getText();
    String jdate=date.getText();
    String pnr=l1.getText();

    try{
        Class.forName("java.sql.Driver");
        con=DriverManager.getConnection("jdbc:mysql://localhost/railway","root","ridhi");
        st =con.prepareStatement("INSERT INTO pnr(pnr_no,Train_Number,Train_Name,From_m,T_o,Date,Class,Reserved_Upto,Boarding_Pt,no_tickets,S_No,Name,Age,Gender,berth_preference,Quota) values(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)");

        st.setString(1, S_No);
        st.setString(2, Name);
        st.setString(3, Age);
        st.setString(4, Gender);
        st.setString(5, berth_preference);
        st.setString(6, Quota);

        st.executeUpdate();
        index++;

        this.setVisible(true);
        new payment().setVisible(true);
    }
    catch(Exception e){
        JOptionPane.showMessageDialog(null,e.getMessage());

    }
}

错误：

【问题讨论】：

标签： java sql jdbc jtable

【解决方案1】：

将此更改为此 jtable 列是基于零索引的。如果您有 6 个 jtable 列，则最大列索引是 5 而不是 6 。错误是因为这个，但如果您想获得第一行，则关心行索引 2 然后@ 987654321@不是getValueAt(1, n);

String S_No = (String) jTable1.getValueAt(row, 0);
String Name = (String) jTable1.getValueAt(row, 1);
String Age = (String) jTable1.getValueAt(row, 2);
String Gender = (String) jTable1.getValueAt(row, 3);
String berth_preference = (String) jTable1.getValueAt(row, 4);
String Quota = (String) jTable1.getValueAt(row, 5);// 5 not 6

您也应该在准备好的语句中具有相同的列数。

 st =con.prepareStatement("INSERT INTO pnr(pnr_no,Train_Number,Train_Name,From_m,T_o,Date,Class,Reserved_Upto,Boarding_Pt,no_tickets,S_No,Name,Age,Gender,berth_preference,Quota) values(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)");

.................................................. ....................................

 st.setString(1, S_No);
 st.setString(2, Name);
 st.setString(3, Age);
 st.setString(4, Gender);
 st.setString(5, berth_preference);
 st.setString(6, Quota);

你应该有，你错过了列电话号码火车号码

 st.setString(1, pnr);
 st.setString(2, tno );

【讨论】：

@ridhi 是的对不起 6 列表示第 0,1,2,3,4,5 列不是 1,2,3,4,5,6
@ridhi 将 6 更改为 5 后，能否发布新的错误消息。也可以将 JOptionPane.showMessageDialog(null,e.getMessage()); 更改为 e.printStackTrace(); 以避免弹出
@ridhi 如果你的 mysql 表有 10 列，那么你准备好的也应该有 10 个准备好的语句应该有。在你的代码中只有 6 个 st.setString() 你应该添加所有列，比如 setString 或 int对于电话号码？火车号码
@ridhi 是的，但是对应于st =con.prepareStatement("INSERT INTO pnr(pnr_no,Train_Number,Train_Name,From_m,T_o,Date,Class,Reserved_Upto,Boarding_Pt,no_tickets,S_No,Name,Age,Gender,berth_preference,Quota) values(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)"); st.setString(1,x) 的值，x 应该是 pnr_no 的值，即 pnr st.setString(2,x) ，x 应该是 pTrain_Number 的值，即 tno
@ridhi 它是st.setString(1,x) 因为它不是 jtable 它是用于准备好的语句，它从索引 1 开始

【解决方案2】：

当显示 ArrayIndexOutOfBoundsException 时：如果我们请求的索引为负数，或者大于或等于数组的大小，则 ArrayIndexOutOfBoundsException 被抛出。在你的情况下，java.lang.ArrayIndexOutOfBoundsException: 6 >= 6。
