java time  Java 8   You can also use the java time package in Java 8 and convert your java util Date object to a java time LocalDate object and then just use the getMonthValue   method   Date date   new Date    LocalDate localDate   date toInstant   atZone ZoneId systemDefault    toLocalDate    int month   localDate getMonthValue      Note that month values are here given from 1 to 12 contrary to cal get Calendar MONTH  in adarshr s answer which gives values from 0 to 11   But as Basil Bourque said in the comments  the preferred way is to get a Month enum object with the LocalDate  getMonth method
