About DateFormat from K&B

[Andry Dub]

Hi! This code

Date d1 = new Date(1000000000000L);
 
DateFormat[] dfa = new DateFormat[6];
dfa[0]=DateFormat.getInstance();
dfa[1]=DateFormat.getDateInstance();
dfa[2]=DateFormat.getDateInstance(DateFormat.SHORT);
dfa[3]=DateFormat.getDateInstance(DateFormat.MEDIUM);
dfa[4]=DateFormat.getDateInstance(DateFormat.LONG);
dfa[5]=DateFormat.getDateInstance(DateFormat.FULL);
 
for(DateFormat df :mrgreen: fa){
     System.out.println(df.format(d1));
}

on my machine produces this output:

09.09.01 5:46
09.09.2001
09.09.01
09.09.2001
9 Сентябрь 2001 г.
9 Сентябрь 2001 г.

which is different from

9/8/01 7:46 PM
Sep 8, 2001
9/8/01
Sep 8, 2001
September 8, 2001
Saturday, September 8, 2001

My question: will this play role on the exam that on my locale output is different? For example, i will check 09.09.01 5:46 while right answer is 9/8/01 7:46 PM

no.
don't worry, it will be clear what to chose.
My experience was that it was a fair exam that tests your knowledge of java, it doesn't try to trick you and make you lose points on unclear questions.
I said it once and I'll say it again, if you do good on K&B, you should do good (about 10% better actually) on the exam.

When you use DateFormat.getInstance(), it will get the default Locale.
On the real exam it's very clear. There no ambiguity about the Locale
to use. Don't worry !!!
But for the exam's preparation, i will suggest you to work with US locale.

Good luck !!!
