Why the error is occurring? I have included:

 import java.util.*;
    import java.io.*;
    import java.sql.*;

1. the 2 param method in PreparedStatement for setDate takes a Calendar, not a String
2. the 2 param method in PreparedStatement for setDate takes a Calendar, not a String,
3. the 2 param method for setInt takes two ints, not and int and a String.
4. you already have another field in your main method called e.

The compiler tells you everything you needd to know:

setInt(int,int) in java.sql.PreparedStatement cannot be applied to (int,java.lang.String)

This means, you are passing a Value of Type String to a methods witch needs a int. The API-Doc of PreparedStatement will show you, that there is a Method setString(int,String) which will take a String as second Parameter.

Maybe you wanted to call ps.setInt(2, 88349);

There ist a valiable called e already defined in that scope.
