Java Question

The result set is not updatable java-Mssql

I am working with java and Mssql. But I am a beginner. I have connected sql but when I want to insert data in sql, I have a problem.

code:

private void jButton3ActionPerformed(java.awt.event.ActionEvent evt) {
try{
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
Connection con =DriverManager.getConnection("jdbc:sqlserver://localhost:1433;databaseName=Hastane;user=Test ;password=Sz04022010;");
Statement komut = con.createStatement();
ResultSet as=komut.executeQuery("select max(PersonelID) from dbo.tbl_personel");
int a=Integer.parseInt(as.getString("SicilNo"));
a++;
jLabel13.setText(Integer.toString(a));}
catch (SQLException ex) {
Logger.getLogger(Personel.class.getName()).log(Level.SEVERE, null, ex);
} catch (ClassNotFoundException ex) {
Logger.getLogger(Personel.class.getName()).log(Level.SEVERE, null, ex);
} }

Add as.next() between these rows:

ResultSet as=komut.executeQuery("select max(PersonelID) from  dbo.tbl_personel");
int a=Integer.parseInt(as.getString("SicilNo"));

ResultSet has a built-in index which by default is 0. the next() method increments that index allowing you to read values from the first row.
