Creating the PreparedStatement
-------------------------------------
=>By calling prepareStatement() method on the Connection object,
java.sql.PreparedStatement object is created.

PreparedStatement preparedStatement=connection.prepareStatement("SQL statement");

For eg.
PreparedStatement preparedStatement1=connection.prepareStatement("INSERT INTO ACCOUNT VALUES(?,?,?)");
PreparedStatement preparedStatement2=connection.prepareStatement("UPDATE ACCOUNT SET BALANCE=BALANCE+? WHERE ACCNO=?");
PreparedStatement preparedStatement3=connection.prepareStatement("DELETE FROM ACCOUNT WHERE ACCNO=?");
PreparedStatement preparedStatement4=connection.prepareStatement("SELECT BALANCE FROM ACCOUNT WHERE ACCNO=?");


Binding of Parameters
-------------------------
=>Supplying values to the place holders(question marks) is nothing but
binding of parameters.

=>By calling setter methods on PreparedStatement object, parameter binding
is performed.

For eg.   
          preparedStatement1.setInt(1,100001);
          preparedStatement1.setString(2,"Rama");
	  preparedStatement1.setDouble(3,50000);
             
Submitting the SQL Statement
-----------------------------------
By calling executeUpdate() OR executeQuery() method on the PreparedStatement
object, SQL Statement is submitted to the DBMS.
For eg.
preparedStatement1.executeUpdate();
