How to convert JAVA.SQL.DATE date in YYYY/MM/DD format into DD/MM/YYYY

Question

i am using informix database which accepts date value in the form of DATE format......
the other part of my application takes date from the field in DD/MM/YYYY format...so i have to convert my java.sql.date in YYYY/MM/DD fromat into DD/MM/YYYY fromat of same type before inserting into db......
but using parse method in SimpleDateFormat class can get the result only in java.util.date format...
and also using format method can result only in string conversion........

Maybe you mean Informix (fronted by JDBC) expects date values as java.sql.Date objects?
the other part of my application takes date from the field in DD/MM/YYYY format...
so i have to convert my java.sql.date in YYYY/MM/DD format into DD/MM/YYYY format of same type before inserting into db......I am not sure why you are talking about formats here.
There is no formatting inherent in a java.util.Date object
nor in a java.sql.Date object.
but using parse method in SimpleDateFormat class can get the result only in java.util.date format...
and also using format method can result only in string conversion........You can easily create a java.sql.Date object from a java.util.Date object.
String s = "31/12/2010";
java.util.Date ud = new java.text.SimpleDateFormat("dd/MM/yyyy").parse(s);
java.sql.Date sd = new java.sql.Date(ud.getTime());
ud = sd; // java.sql.Date extends java.util.Date so no conversion is needed
