I am trying to format date with Integer but they both work separately fine but when I put them together it throws following error.
Exception in thread "main" java.util.IllegalFormatConversionException: d != java.util.Date
at java.util.Formatter$FormatSpecifier.failConversion(Unknown Source)
at java.util.Formatter$FormatSpecifier.printInteger(Unknown Source)

at java.util.Formatter.format(Unknown Source)
at java.util.Formatter.format(Unknown Source)
at java.lang.String.format(Unknown Source)
at Test.main(Test.java:10)
Code:
public class Test {
public static void main(String[] args) {
String format = "http://az.website.com/api/calendar/date/%1$tY-%1$tm-%1$te/user_id/%d";
Date date = Calendar.getInstance().getTime();
System.out.println(String.format(format, date, 23));
}
}
If I remove date format %1$tY-%1$tm-%1$te
then it starts working fine but together it throws IlelgalFormatConversionExpception
.
What's wrong with this code ?
Update
Code that runs but produces wrong out put.
public class Test {
public static void main(String[] args) {
String format = "http://az.website.com/api/calendar/date/%1$tY-%1$tm-%1$te/user_id/%2$%d";
Date date = Calendar.getInstance().getTime();
System.out.println(String.format(format, date) + 23);
}
}
Output: http://az.website.com/api/calendar/date/2014-01-30/user_id/%d23
Code that produce erros:
public class Test {
public static void main(String[] args) {
String format = "http://az.website.com/api/calendar/date/%1$tY-%1$tm-%1$te/user_id/%2$d";
Date date = Calendar.getInstance().getTime();
System.out.println(String.format(format, date) + 23);
}
}
Output:

Using Java 1.6 Android 4.3 also tried on
java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)
Update
@Sotirios Delimanolis is really a life saver. I was calling the method wrongly.
Wrong --> System.out.println(String.format(format, date) + 23);
Right --> System.out.println(String.format(format, date, 23));
