How can I format this String with double x,y,total to two decimal places. String output = (x + " + " + y + " = " + total);
String ouput = String.format("%.2f + %.2f = %.2f",x,y,total);
System.out.println(output);
will give you the output with 2 decimal places or you can use DecimalFormat as well.
I've got a String variable for my time :
var $myTime:String;
//Some calculation
trace(myTime);
// Result is : 14:25 (for example)
I'm looking for a way to convert this string ("14:25" in this example) to a simple AM / PM format.
So in this example it would be, for example, 2 PM
Any idea how I can simply do that ?
You can use DateFormatter class to set your wished pattern.
You can write your code as follow:
var df:DateFormatter = new DateFormatter();
df.formatString = "YYYY-MM-DD L:NN:SS";
df.format(myTime);
Where L is HOUR with PM/AM; NN are the minutes SS seconds.
You can see the complete guide, about DateFormatter pattern, here
var myTime:Date = new Date();
var timeString:String;
if (myTime.getHours() > 12)
{
timeString = String((myTime.getHours() - 12) + ":" + myTime.getMinutes() + " PM");
}
if (myTime.getHours() == 12)
{
timeString = String(myTime.getHours() + ":" + myTime.getMinutes() + " PM");
}
if (myTime.getHours() < 12)
{
timeString = String(myTime.getHours() + ":" + myTime.getMinutes() + " AM");
}
trace(timeString);
That should do the trick.
I am trying to write an cron expression with a specific start time and end time everyday. i.e.
every minute from 10:15 to 17:35 everyday
One possible solution for this is writing 3 different cron expressions like this:
0 15-59 10 * * *
0 * 11-17 * * *
0 0-35 17 * * *
Is there any possible way to write this in one single cron expression ?
There is no other way to achieve it using single crone expression but to specify multiple crone expressions for specific startDate and endDate.
There is a slight modification in second crone expression though (highlighted one)
0 15-59 10 * * * (Every minute between 10:15 AM and 10:59 AM)
0 * 11-16 * * * (Every minute, between 11:00 AM and 04:59 PM)
0 0-35 17 * * * (Every minute between 05:00 PM and 05:35 PM)

Apologies, as I'm sure this is a stupid question, but...
Please could anyone explain to me why this:
public class java {
public static void main(String[] args) {
byte zero = 0;
short one = 1;
int three = 3;
long one2 = 1;
float onepointnought = 1.0f;
double onedotnone = 1.0;
char letterh = 'H';
char letterw = 'w';
char letterr = 'r';
char letterd = 'd';
boolean bool = true;
String output = letterh + three + one + one2 + zero + " " + letterw + zero + letterr + one + letterd + " " + (onepointnought+onedotnone) + " " + bool;
System.out.println(output);
} }
Is outputting:
77 w0r1d 2.0 true
I'm expecting it to say "H3ll0 w0r1d 2.0 true"
It's from the interactive online java tutorials over at http://www.learnjavaonline.org/
Thanks!
Neil.
In this sentence
String output = letterh + three + one + one2 + zero + " " + letterw + zero + letterr + one + letterd + " " + (onepointnought+onedotnone) + " " + bool;
the letterh contains 'H' whose ASCII value is 72 & the addition of three + one + one2 + zero is 5 because these are non-string variables, so it is displaying (72 + 5)77 in the result,
you must convert three , one , one2 , zero to sting variable
I'm reading from an oracle database a date in this format: dd/mm/yyyy HH24:mi:ss.
when i write a query i have to write the whole date with seconds and minutes.
i need a way to write a query without giving this HH24:mi:ss.
how can i enter a date like 4/7/2011 and get it in this format dd/mm/yyyy HH24:mi:ss
this is the query:
q = "select * from MPOS t where t.TRANSACID='" + n +
"'and t.REPORTDATE between to_date('" + st + "', 'dd/mm/yyyy HH24:mi:ss')"
+ " and to_date('" + end + "', 'dd/mm/yyyy HH24:mi:ss')";
where st and end are DateTime
try use ToShortDateString():
q = "select * from MPOS t where t.TRANSACID='" + n +
"'and t.REPORTDATE between to_date('" + st.ToShortDateString() + "', 'dd/mm/yyyy')" +
" and to_date('" + end.ToShortDateString() + "', 'dd/mm/yyyy')";
I think you will also have to change the order of dd and mm so it would be 'mm/dd/yyyy'
