Let’s say we have Long object here.Long myObj = new Long("9879");Now, if we want to convert this Long to short primitive data type. For that, use the in-built shortValue() method −// converting to short primitive types short shortObj = myObj.shortValue(); System.out.println(shortObj);In the same way convert Long to another numeric primitive data type int. For that, use the in-built intValue() method −// converting to int primitive types int intObj = myObj.intValue(); System.out.println(intObj);The following is an example wherein we convert Long to numeric primitive types short, int, float, etc −Example Live Demopublic class Demo { public static void main(String[] args) ...

To check for Long overflow, we need to check the Long.MAX_VALUE with the subtracted long result. Here, Long.MAX_VALUE is the maximum value of Long type in Java.Let us see an example wherein long integers are subtracted and if the result is still more than the Long.MAX_VALUE, then an exception is thrown −The following is an example showing how to check for Long overflow −Example Live Demopublic class Demo { public static void main(String[] args) { long val1 = 70123; long val2 = 10567; ...

In this article, we will learn to display the date and time in uppercase using Java. Working with date and time in Java is a common requirement in various applications, logging, scheduling, or data processing. Different Approaches The following are the two different approaches to display the date and time in uppercase using Java − Using Formatter and Calendar Using DateTimeFormatter Using Formatter and Calendar The Formatter class in Java allows us to format date and time using the %Tc specifier. We can then convert the output to uppercase using ... Read More
