Is this preparedSatement possible?

Question

G'Day, G'day!!
I am just wondering if this is possible?
I am using MSAccess and have a practice table with 3 columns, a gui with 3 JTextFields and a button called save, when I click on save I want the preparedStatement to insert the values into the database. I'll post the relevent code.
if (e.getSource() == save){
//I'llskip the connection code for brevity
try{
boolean abool;
String a = textField1.getText();
if(a.equals("")){abool = false;}
if(!a.equals("")){abool = true;}
String b = textField2.getText();
Stringc = textField3.getText();
PreparedStatement pstmt = con.prepareStatement("INSERT INTO TIMESHEET VALUES ( "+
pstmt.setBoolean(1, abool);
pstmt.setString(2, b);
pstmt.setString(3, c);
pstmt.executeUpdate();
pstmt.close();
con.close();
}catch(SQLException ex){System.err.println("SQLException: " + ex.getMessage());}
As it runs now, I get the error:
SQLException: [Microsoft][ODBC Microsoft Access Driver] Optional feature not implemented.
I haven't run into this error before, does that mean that my driver does not support this function or am I doing something wrong?
I have used preparedStatements in the form of
PreparedStatement pstmt = con.prepareStatement("UPDATE TIMESHEET SET "+
"COL1 = ? WHERE NAME LIKE ?)";
pstmt.setFloat(1, 2.25);
pstmt.setString(2, myname);
pstmt.executeUpdate();
And this works perfectly fine, if anybody could offer a brief explanation that would be great. I have searched all 114 archives on preparedStatements and couldn't find an answer, and I am sure it is a simple one!!!!
Cheers and Thanks alot!! Oz.

Actually disregard,
I am really sorry to have wasted you time. I found the problem.
In my text program it was actually
boolean abool = true
String a = text1.getText();
if(a.equals("")){abool = true;}
if(!a.equals("")){abool = false;}
String b= text2.getText();
String c= text3.getText();
float f = Float.valueOf(c).floatvalue();
(the cols were -col1 bit, col2 varchar(10), col3 float)
and the pstmt was actually
pstmt.setBoolean(1,abool);
pstmt.setString(2,b);
pstmt.setFloat(3.f);
so I changed the last one to pstmt.setString(c) which is in the format of a float and it took it that way.
But I don't understand why it wouldn't take the setFloat, and gave the option new implemented error?
Once again i apologize, learners error!!!
