ParseExeption with Date?

Question

I got an exception while parsing date format?

java.text.ParseException: Unparseable date: "10-10-2016"

at this line:

newSelection5 = DateFormat.getDateInstance().parse((String)CalDcB.getSelectedItem());

The date is set as: CalDcB = new DateComboBox(new SimpleDateFormat("dd-MM-yyyy", Locale.ENGLISH));

I tried also without Locale.English.

There was also a danger Alert "null".

Answer 1

You could construct a SimpleDateFomat that matches your format and use that.

DateFormat df = new SimpleDateFormat("dd-MM-yyyy", Locale.ENGLISH);
Date d = df.parse("10-10-2016");

Answer 2

tl;dr

LocalDate.parse( 
    "30-10-2016" , 
    DateTimeFormatter.ofPattern( "dd-MM-uuuu" ) 
)

LocalDate

FYI, you are using troublesome old date-time classes now legacy. Supplanted by the java.time classes.

The LocalDate class represents a date-only value without time-of-day and without time zone.

DateTimeFormatter f = DateTimeFormatter.ofPattern( "dd-MM-uuuu" );
LocalDate ld = LocalDate.parse( "30-10-2016" , f );

ld.toString(): 2016-10-30

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old date-time classes such as java.util.Date, .Calendar, & java.text.SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to java.time.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations.

Where to obtain the java.time classes?

• Java SE 8 and SE 9 and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • The ThreeTenABP project adapts ThreeTen-Backport (mentioned above) for Android specifically.
  • See How to use….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

Answer 3

Try this:

SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd-MM-yyyy", Locale.ENGLISH);
    Date date = simpleDateFormat.parse("10-10-2016");

Answer 4

Okay, it works without an exception.

I used:

DateFormat df = new SimpleDateFormat("dd-MM-yyyy");
newSelection5 = df.parse((String)CalDcB.getSelectedItem());

Thanks
