Converting Date instance to Instant instance

In this post under DateTime, I will show how to convert an instance of “Date” class to “Instant” instance. Below is the code to that will do the conversion. Date date = new Date(); Instant instant = date.toInstant(); As shown in the above code snippet, first we create a “Date” instance and store in “date”…… Continue reading Converting Date instance to Instant instance

Converting Instant instance to Date instance

In this post under DateTime, I will show how to convert an instance of “Instant” class to “Date” instance. Below is the code to that will do the conversion. Instant instant = Instant.now(); Date date = Date.from(instant); “now” static method of “Instant” class will return an “Instant” instance representing the current date time. Then we…… Continue reading Converting Instant instance to Date instance

Serializing and De-Serializing Date object to and from a custom pattern

In this post under Java, I will show with example how to serialize and de-serialize Date object using a custom pattern. In the previous post, we used “SimpleDateFormat” class to serialize and de-serialize Date object using a pattern obtained based on system default locale. This pattern was figured out by Java and was not provided…… Continue reading Serializing and De-Serializing Date object to and from a custom pattern

Serializing and De-Serializing Date object to and from pattern

In this post, I will show with example how to serialize and deserialize Date object. Java provides “SimpleDateFormat” class to serialize and deserialize Date objects. Below is an example Main class 1 package datetime; 2 3 import java.text.ParseException; 4 import java.text.SimpleDateFormat; 5 import java.util.Date; 6 7 public class Example1 { 8 public static void main(String[]…… Continue reading Serializing and De-Serializing Date object to and from pattern

Getting a list of ClassPath scanned by a Java Program

In this post under Java, I will post the code which will list all the paths a Java Program uses to search for linked jars and resources. Below is the main method Main class 1 package classloader; 2 3 import java.net.URL; 4 import java.net.URLClassLoader; 5 6 public class ClassPath { 7 public static void main(String[]…… Continue reading Getting a list of ClassPath scanned by a Java Program

Externalizing the logger and handler configuration to properties file

In all my previous posts under java logging, I have configured logger and handler programmatically. We can externalize those configurations to properties file also. The advantage of this approach is that we can change configurations at any time without recompiling java class. In this post I will show with example how to do that. Let’s…… Continue reading Externalizing the logger and handler configuration to properties file

BiConsumer’s andThen Example

In this post under Java, we will explain with an example the andThen method under BiConsumer functional interface. BiConsumer’s andThen method is used to chain one BiConsumer interface implementation with one or more BiConsumer interface implementations. Lets consider an example. I have a list of TCS employees with the class structure as shown below TCSEmployee…… Continue reading BiConsumer’s andThen Example

BiFunction’s andThen Example

In this post under Java, we will explain with an example the andThen method under BiFunction functional interface. BiFunction’s andThen method is used to chain a BiFunction interface implementation with one or more Function interface implementations. Lets consider an example. I have a list of employess with their salary and percent of bonus to apply…… Continue reading BiFunction’s andThen Example
