Use the divide method to divide one BigDecimal to another in Java. The method returns a BigDecimal whose value is (this / divisor), and whose preferred scale is (this.scale() - divisor.scale()).If the exact quotient cannot be represented (because it has a non-terminating decimal expansion) an ArithmeticException is thrown.The following is ...

The “KK” format in Java Date is used to display hour in 00-11.. Use SimpleDateFormat("KK") to get the same format −// displaying hour in KK format SimpleDateFormat simpleformat = new SimpleDateFormat("KK"); String strHour = simpleformat.format(new Date()); System.out.println("Hour in KK format = "+strHour);Above, we have used the SimpleDateFormat class, therefore the ...

We have the following BigDecimal value −BigDecimal val1 = new BigDecimal("37578975587.876876989");We have set the decimal place to be −int decPlaces1 = 3;Now, we will use the ROUND_DOWN field to set the rounding mode to round towards zero −// ROUND_DOWN val1 = val1.setScale(decPlaces1, BigDecimal.ROUND_DOWN); String str1 = val1.toString(); System.out.println("Result = "+str1);To ...

Firstly, let us declare and initialize three long values −long val1 = 98799; long val2 = 98567; long val3 = 98768;Now, find the maximum of three long values using the following condition −// checking for maximum if (val2 > val1) { val1 = val2; } if (val3 ... Read More

Let’s create BigDecimal value with a stringBigDecimal val1 = new BigDecimal("37578975.8768"); BigDecimal val2 = new BigDecimal("62567878.9768");You can also set the above as −String str1 = “37578975.8768”; BigDecimal val1 = new BigDecimal(str1); String str2 = “62567878.9768”; BigDecimal val2 = new BigDecimal(str2);Now, you can also perform operations like −val1 = val1.add(val2); System.out.println("Addition ...

The Z means "zero hour offset", also known as "Zulu time" (UTC) in the ISO 8601 time representation. However, ACP 121 standard defines the list of military time zones and derives the "Zulu time" from the Greenwich Mean Time (GMT).TimeZone can be formatted in z, Z or zzzz formats.The following ...
