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

Observable error and empty method
In this post under RxJava, I will introduce you to Observable class’s two static methods “error” and “empty” methods. The error method creates an Observable instance that will send the error thrown to the Observer/Subscriber. The empty method creates as Observable instance that will not send any item, it just generate completion event to the…… Continue reading Observable error and empty method
Observable interval method
In this post under RxJava, I will explain with example how to use the static “interval” method of Observable class. This static method generates a stream of numbers of data type long with a time gap between generation of numbers. They are two overloaded versions of “interval” method, one that accepts an intial delay in…… Continue reading Observable interval method
Observable range method
In this post under RxJava, I will explain with example how to use the static “range” method of Observable class. This static method generates a stream of integers which fall within the specified range. The method takes two arguments1) The starting integer2) The count of sequential integers from the starting integer. Below is an example…… Continue reading Observable range method
Creating Observable from collections
In this post under RxJava, I will explain with example how to create Observable instances from collections. The Observable api provides methods to create Observable instance from Java Array, Collections, and Streams. Below is an example of it Example 1 import java.util.ArrayList; 2 import java.util.List; 3 4 import io.reactivex.rxjava3.core.Observable; 5 6 public class Example2 {…… Continue reading Creating Observable from collections
Observable (Observable’s just method) With Simple Example
In this post under RxJava, I will explain what is an Observable with an example. An Observable is a push based stream of data/events. In other words an Observable pushes items of type T directly to the observer or indirectly to an observer through a chain of operators. Types of Observable They are four types…… Continue reading Observable (Observable’s just method) With Simple 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
