Bonjour àtous !
I'm a new gcj user and I try a program which
does work with javac/java but rise an error
with gcj.
My first impression is very hopefull, and I hope
to use java(gcj) instead of c++.
My gcl version come from cvs about a month ago (not sure)
and I'm trying to do some test to compare C and GCJ
and the feature suported by gcl relatively to javac (jdk)
> gcj --version
2.97
(should'nt be a more verbose option like --version2
giving compil date and anything usefull for
version identification?)
My plateform is linuxppc on powermac blue G3 ( 2.2.17rms1)
(and I hope MacOS-X as soon as possible with X11 and full
gcc :-)
------------------------------------------------------------
I rise an error with date format in the following :
Hier is the code :
import java.util.*;
import java.text.SimpleDateFormat;
public class Test {
public static void main(String[] args) {
// on déclare des formateurs de date et de temps :
SimpleDateFormat df =
new SimpleDateFormat( "yyyy-MM-dd HH:mm:ss.SSSS");
SimpleDateFormat tf =
new SimpleDateFormat( "mm'mn' ss.SSS's'");
Date startDate = new Date();
System.out.println ("Début à: " + df.format(startDate) );
Date endDate = new Date();
System.out.println ("Fini à: " + endDate);
Date duree = new Date(endDate.getTime() - startDate.getTime());
// System.out.println ("durée : " + duree/1000 +
// "." + duree%1000 + "s");
System.out.println ("durée : " + tf.format(duree));
return;
} // main
}
