Learn how to use synchronous and asynchronous callbacks in Java—including callbacks with lambda expressions, CompletableFuture, and more.
There are various ways of interacting with Atlas. Since we are building a service using a serverless function in Java, my preference is to useMongoDB Java driver. So, let's add the dependency for the driver in thebuild.gradlefile. dependencies{implementation 'com.microsoft.az...

so I always like to remind developers that all of the interfaced defined in this package follow all of the standard, pre Java 8 rules for implementing interfaces. As such, you can incorporate the functional Consumer interface into your code simply by creating...
Sometimes, we may want to create functions which can have undetermined number of parameters. For one or two parameters, we can use optional parameters or default values. But what if number of parameters is not known, or can vary at runtime. ...
Just as in the predicate lambda, the above is the most explicit way to define and use a consumer so that you can understand it best. Functions Afunctionis used to transform a value which is passed as an argument. It has a methodapplywhich returns the transformed value. For example, you...
The output prints the second array element,e. Just as printing it, you could use it in any other way where acharvalue is suitable. Furthermore, you can also iterate over all the array elements using aforeachloop as explained in our tutorialHow To Use Loops in Java. A loop is a struct...
When executing an entity query (e.g. JPQL, HQL or Criteria API), you can use any SQL function without having to register it as long as the function is passed directly to the WHERE clause of the underlying SQL statement. However, if the SQL function is used in the SELECT clause, and ...
Objects and global objects in functions Speaking of objects and global objects, thethis keywordattains the value of an object when used inside a function and owns that function. When we call a function without an object and use this inside it, it automatically becomes the global object or atta...
In this tutorial, we’ll look at the challenges of using any RDBMS within a Lambda, and how and when Hibernate can be useful. Our example will use the Serverless Application Model to build a REST interface to our data. We’ll look at how to test everything on our local machine usingDo...
