Hi people,
I am just learning java.I have been creating a project which involves JDBC Connectivity.I find that the statements,
String string_dob=text_dob.getText();
//Converting string to date
System.out.println(string_dob);
s.Info_DOB=Date.valueOf(string_dob);
runs perfectly fine in the method insert() and throws up an illegal Exception in the method UPDATE.This is the error I get when I pass a date "1979-05-02"
