Question

From a web service i am getting a date format as 1994-09-11 in my android app i need to display this as Sep 11

My code is as follows

Date date_temp = null;
String d_temp = null;
DateFormat formatter;
static SimpleDateFormat datesdf = new SimpleDateFormat("yyyy MMM dd");

public String changeDateformat(String date_str)
    {
        Log.e("date_str ",""+date_str);
        try 
        {
            date_temp = (Date)formatter.parse(date_str);
            Log.e("date_temp ",""+date_temp);
            d_temp = null;
            d_temp = datesdf.format(date_temp);
            Log.e("d_temp ",""+d_temp);
        }
        catch (ParseException ex) 
        {
            ex.printStackTrace();
        }
        catch (java.text.ParseException e) 
        {
            e.printStackTrace();
        }
        return d_temp;
    }

When the above method is called, the first log value is been printed(the value which i get from the web), then my app gets crashed saying that

09-10 13:02:44.920: E/AndroidRuntime(3503): java.lang.NullPointerException
09-10 13:02:44.920: E/AndroidRuntime(3503): at xxxxxxxxxxx(Events.java:206)

Here line number 206 is the first line inside try catch of the above method.
What is wrong with my code, pls suggest me…..

Answer 1

DateFormat formatter; <– it is never initialized. so you are calling a methode on null.

Maybe you want to use:

static SimpleDateFormat datesdf = new SimpleDateFormat("yyyy MMM dd");

Instead of formatter.
