Hej! Jag har problem med datumhantering i en klass. I klassen hämtar jag dagens datum och dagens tid. Tiden räknar jag upp i en for-loop med en minut per varv. Koden ser ut som följer:

String dateOut;
DateFormat formaterare=DateFormat.getDateInstance(DateFormat.SHORT); //denna rad hör till den övre
Date idag=new Date();
dateOut=formaterare.format(idag);
String[]datum=new String[50];
for(int i=0;i<datum.length;i++)
{
datum[i]=dateOut;
}
int timma=idag.getHours();i
nt minuter=idag.getMinutes();
String [] tid=new String[50];
for(int i=0;i<tid.length;i++)
{
minuter=minuter + 1;
if(minuter>59)
{
timma=timma+1;
minuter=0;
}
tid[i]=timma+"."+minuter;
}

Problemet är att jag i samma klass har kontakt med en databas. Jag har därför importerat java.sql och java.util.
När jag så kompilerar klagar kompilatorn på att:"reference to Date is ambigious, both class java.sql.Date in java.sql and class java.util.Date in java.util match Date idag = new Date;".

Kan någon förklara vad jag skall göra åt detta?

Hello.

Jag antar att du borde kunna göra så här:

String dateOut;
DateFormat formaterare=DateFormat.getDateInstance(DateFormat.SHORT); //denna rad hör till den övre
java.util.Date idag=new java.util.Date();
dateOut=formaterare.format(idag);
String[]datum=new String[50];
for(int i=0;i<datum.length;i++)
{
datum[i]=dateOut;
}
int timma=idag.getHours();i
nt minuter=idag.getMinutes();
String [] tid=new String[50];
for(int i=0;i<tid.length;i++)
{
minuter=minuter + 1;
if(minuter>59)
{
timma=timma+1;
minuter=0;
}
tid[i]=timma+"."+minuter;
}

Alltså importera java.util.Date när du skapar Date objektet. istället för att importera Date-klassen i början av filen.

Jag vill minnas att classen List har samma dilemma... men jag är inte säker.

Vet inte om det finns en bättre/smartare lösning.
Men det bör funka :-Þ

Har sagt det förr och säger det igen - använd inte klassen Date!
Använd klassen:
com.ms.wfc.app.Time


Den har funktioner för att lägga till och dra ifrån olika tidsenheter, förutom
det så kan man använda alla metoderna. Klassen Date verkar vara på
väg ut i periferin för där är över hälften av metoderna ej rekommenderade
att användas. (se nedan:)
