jTableから14行のデータをTextfieldに配置するのに問題がありますか？私はコーディングに新しいです。java.lang.ArrayIndexOutOfBoundsException：7> = 7
try {
String data = jSubject.getSelectedItem().toString();
Class.forName("org.h2.Driver");
Connection conn = DriverManager.getConnection("jdbc:h2:dist/Database/./h2database/recordDB", "test", "test");
Statement st = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_UPDATABLE);
String sql = "Select * from " + data;
ResultSet rs = st.executeQuery(sql);
DefaultTableModel a = (DefaultTableModel) jTable2.getModel();
a.setRowCount(0);
while (rs.next()) {
String q = rs.getString("Subjects");
a.addRow(new Object[]{q});
}
JTableHeader th = jTable2.getTableHeader();
TableColumnModel tcm = th.getColumnModel();
TableColumn tc = tcm.getColumn(0);
tc.setHeaderValue("Subjects");
th.repaint();
DefaultTableModel xa = (DefaultTableModel) jTable2.getModel();
// int selectedRowIndex = jTable2.getSelectedRow();
s1.setText(xa.getValueAt(0, 0).toString());
s2.setText(xa.getValueAt(1, 0).toString());
s3.setText(xa.getValueAt(2, 0).toString());
s4.setText(xa.getValueAt(3, 0).toString());
s5.setText(xa.getValueAt(4, 0).toString());
s6.setText(xa.getValueAt(5, 0).toString());
s7.setText(xa.getValueAt(6, 0).toString());
s8.setText(xa.getValueAt(7, 0).toString());
s9.setText(xa.getValueAt(8, 0).toString());
s10.setText(xa.getValueAt(9, 0).toString());
s11.setText(xa.getValueAt(10, 0).toString());
s12.setText(xa.getValueAt(11, 0).toString());
s13.setText(xa.getValueAt(12, 0).toString());
s14.setText(xa.getValueAt(13, 0).toString());
} catch (ClassNotFoundException ex) {
Logger.getLogger(CBL.class.getName()).log(Level.SEVERE, null, ex);
} catch (SQLException ex) {
Logger.getLogger(CBL.class.getName()).log(Level.SEVERE, null, ex);
}
私はそれは常に私にjava.lang.ArrayIndexOutOfBoundsExceptionを与えるコード実行するたび：7> = 7エラーが。
