Question

I am trying to create a Date object from an input String. The code snippet that I have written is :

inputs are like : effDate = "03/09/2012" and ExpiryDate = "08/31/2012"

System.out.println("eff Date: " + effDate); 
SimpleDateFormat formatter = new SimpleDateFormat("MM/DD/yyyy");
Date date = formatter.parse(effDate);
System.out.println("Effective Date = " + formatter.format(date));

The output I get is :

eff Date: 03/09/2012
Effective Date = 01/09/2012

The same happens for the other input as well. like

exp date: 08/31/2012
Expiry Date = 01/31/2012

Does anyone know the reason why its changing the month value from anything(03/08) to 01 ??
Info: I am using jdk1.6 with Eclipse. And running this sample program through JUNIT 4.

Answer 1

new SimpleDateFormat("MM/DD/yyyy"); should be new SimpleDateFormat("MM/dd/yyyy"); (dd instead of DD)

• DD = Day in year
• dd = Day in month
