java - unable to get the desired output while date formatting -

while running below java code

string v_date_str = "03/04/2015"; date v_date = new simpledateformat("mm/dd/yyyy").parse(v_date_str); dateformat formatter = null;  formatter = new simpledateformat("dd-mmm-yyyy"); date date_temp = null; date_temp = (date) formatter.parse("31-dec-2012"); // string of same format formatter out.println("output: " + formatter.format(v_date)); 

i expecting output below.

output: 03-mar-2015 

but getting output

output: 28-dec-2014 

please let me know going wrong , how can fix this.

thanks

you parsing date wrong format. d day in year, not day in month, d. y week year, not year, y. once fix format, code executes expect:

date v_date = new simpledateformat("mm/dd/yyyy").parse(v_date_str);
