Difficulty parsing a string with SimpleDateFormat

Question

I have a date string called allianceStartDate which has the value of

"1/7/2010"

I am trying to convert this date string to util Date object. The code which I have tried is as follows:

Date d = new SimpleDateFormat("dd/mm/yyyy").parse(allianceStartDate);

However the result of this operation is:

Fri Jan 01 00:07:00 GMT 2010

The desired result is a Date object in the format: "01/07/2010".

Thanks for any help offered.

Instead of using Date.parse(String) use Date.format(String). Also as said below, use MM for Month. — CoderMusgrove

Date.format only allows you to pass a Date object as a parameter. — LiamWilson94

It should be "dd/MM/yyyy" not "dd/mm/yyyy", We use mm for minutes not for Month in Java. You should use MM for month.

The date which is returned still is in the incorrect format... I would like it to be displayed as "01/07/2010" for example. I do not want the timestamp or the name of the month or day of the week.

@LiamWilson94 You need to format your printing format too. eg:

DateFormat df=new SimpleDateFormat("dd/mm/yyyy");         Date d = df.parse("01/07/2010");         System.out.println(df.format(d));

I thought that after the SImpleDateFormat parse, the Date object should now be in the correct format?

@LiamWilson94 parsing will give you a date object. it can represent in any format you want.

After parsing your initial text to obtain the Date object you will need to format it usig also a date formater in order to display it as a formatted text. Here is an exemple:

SimpleDateFormat SIMPLE_DATE_FORMATTER = new SimpleDateFormat("dd/MM/yyyy");

public String toSimpleDateFormat(Date d) {
    return SIMPLE_DATE_FORMATER.format(d);
}

Thank you, this explains the difficulty I was having. I thought that after initially parsing the date that it would be in the desired format.
