The Salīdzinot ar() metode ir Integer klases metode java.lang pakotne . Šī metode salīdzina divus veselus skaitļus objektus skaitliski. Tas atgriež vērtības 0 rezultātu, ja Vesels skaitlis ir vienāds ar argumentu Vesels skaitlis, vērtību, kas ir mazāka par 0, ja Vesels skaitlis ir mazāks par arguments Vesels skaitlis un vērtība, kas lielāka par 0, ja Vesels skaitlis ir lielāks par argumentu Vesels skaitlis. Šo metodi nosaka Salīdzināms Interfeiss .

Piezīme. Šo metodi nevar salīdzināt divus dažādu veidu argumentus, tāpēc gan argumentam, gan skaitlim ir jābūt viena veida.
