With Orkes Conductor managed through Orkes Cloud, developers can focus on building mission critical applications without worrying about infrastructure maintenance to meet goals and, simply put, taking new products live faster and reducing total cost of ownership.

Modern software architecture is often broken. Slow delivery leads to missed opportunities, innovation is stalled due to architectural complexities, and engineering resources are exceedingly expensive.

Similar to how we used naturalOrder, we’ll use the reverseOrder method to generate a Comparator that will produce a reverse ordering of employees compared to the one in the naturalOrder example:

Please note, this is a table of rectilinear values, i.e. values for rectilinear lenses; fisheye field of view is a different beast.

The values for Field of View (FOV), sometimes sloppily referred to as "lens view" or better, "angle of view", come up frequently enough at the forums that I thought a list might be helpful for quick reference.

Whether you're just starting out or have years of experience, Spring Boot is obviously a great choice for building a web application.

There’s another option that facilitates overriding the natural ordering of the sort key by providing a Comparator that creates a custom ordering for the sort key:

The Comparator.comparing static function accepts a sort key Function and returns a Comparator for the type that contains the sort key:

The platform comes with interconnected out-of-the-box add-ons for report generation, BPM, maps, instant web app generation from a DB, and quite a bit more:

Again, as we did for int and long keys, let’s look at an example using Comparator.comparingDouble to consider a sort key of type double by ordering the employees array by the salary field:

To see this in action, we’ll use the name field in Employee as the sort key, and pass its method reference as an argument of type Function. The Comparator returned from the same is used for sorting:

The Comparator interface can also effectively leverage Java 8 lambdas. A detailed explanation of lambdas and Comparator can be found here, and a chronicle on the applications of Comparator and sorting can be found here.

We’ll also create an array of employees that we’ll use to store the results of our type in various test cases throughout the tutorial:

Now we can use the other version of thenComparing, thenComparingInt, by changing the lexicographical sequence to name followed by age:

In this section, we’ll cover the nullsFirst and nullsLast functions, which consider null values in ordering, and keep the null values at the beginning or end of the ordering sequence.

Let’s implement Comparable in our Employee class so that we can try the naturalOrder and reverseOrder functions of the Comparator interface:

Machinet's Unit Test AI Agent utilizes your own project context to create meaningful unit tests that intelligently aligns with the behavior of the code. And, the AI Chat crafts code and fixes errors with ease, like a helpful sidekick.

So let’s modify the test above. We’ll override the natural order of sorting by the name field by providing a Comparator for sorting the names in descending order as the second argument to Comparator.comparing:

I built the security material as two full courses - Core and OAuth, to get practical with these more complex scenarios. We explore when and how to use each feature and code through it on the backing project.

We’ll use the Comparator that sorts the employees by name and reverse it so that the employees are sorted in descending order of the name:

How to use the table: Hopefully the table is quite self-explanatory, but let's say you are looking for the Field-of-view of a 50mm lens mounted on an FX body. In the column "Lens Focal Length", go down to the row marked "50mm" and then over to the green area marked "35mm & FX format (1)". The FOV for a 50mm lens would be 39.6 degrees horizontally and 27.0 degrees vertically. Diagonally, the FOV is 46.8 degrees.

Get non-trivial analysis (and trivial, too!) suggested right inside your IDE or Git platform so you can code smart, create more value, and stay confident when you push.

Java 8 introduced several enhancements to the Comparator interface, including a handful of static functions that are of great utility when coming up with a sort order for collections.

There’s also a function, Comparator.comparingInt, which does the same thing as Comparator.comparing, but it takes only int selectors. Let’s try it with an example where we order employees by age:

Given the above logic to compare employees based on the name field, let’s use this function to obtain a Comparator which sorts the employees array in natural order:

Here the ordering will be done by age, and for the values with the same age, the ordering will be done by name. We can see this in the sequence we receive after sorting:
