Det sammenligne med() metode er en metode i Integer-klassen under java.lang-pakke . Denne metode sammenligner to heltal genstande numerisk. Det returnerer resultatet af værdien 0, hvis Integer er lig med argumentet Integer, en værdi mindre end 0, hvis Integer er mindre end argument Heltal og en værdi større end 0, hvis Heltal er større end argumentet Heltal. Denne metode er specificeret af Sammenlignelig Interface .

Bemærk: Denne metode kan ikke sammenlignes med to forskellige typer argumenter, så både argumentet og tallet skal være af samme type.
