In this tutorial, I will show you how to get started with this new open source library from Amazon to build and deploy Deep Learning in Java.
In this quick tutorial, I will show you how to get started with Quarkus new Qute templating engine.
Quarkus is the new Supersonic Subatomic Java framework tailored for GraalVM and HotSpot.
Learn how to deploy Jakarta EE application to Google Cloud Platform (GCP) with Kubernetes.
In this tutorial, I will show you how to deploy Jakarta EE application to Kubernetes.
In this tutorial, we will learn how to create our first JavaFX application.
LinkedHashMap class extends HashMap class and implements the Map interface.
Java LinkedList is a linear data structure, which means the elements are linked using pointers.
Java TreeMap implements the Java Map interface and the key/value pairs in a TreeMap will be sorted in an ascending key order.
Java HashMap implements Map interface and is used for storing items in key/value pairs, and you access a value by its key, and HashMap keys must be unique.
Java HashSet is a collection that contains unique elements and implements the Set interface.
Java ArrayList are dynamic arrays that can grow as needed not like standard Java arrays which are fixed length.
The following statement will create an ArrayList.
To get the current date is really simple in Java, you just instantiate the Date object from the java.util package.
Methods in Java is a block of statements that must be in a class and can be executed by calling it from other places.
Arrays are a collection of elements having same type. To declare an array, we define the variable type with square brackets.
While-loop executes a block of code as long as a specified condition is true.
In this tutorial, you will learn how to create a for loop.
Switch Statement is used when we want to check equality of a variable against number of values.
If statement is the most basic way of test a condition. With the if statement you test if a condition is true or false.
In this tutorial we will learn how to write, compile and run our first Java program.
In this tutorial, we will learn how to secure our services using MicroProfile JWT and Keycloak.
Health checks are used to determine if the service is running, shutdown, lack of disk space or maybe issues with the database connection. In this tutorial, we will use Eclipse MicroProfile Starter to generate a new project.
Few weeks ago, I started to work on an Ebook called Building an API Backend with MicroProfile, you will learn how to create a simple RESTful API backend with MicroProfile.
The project is open source and hosted on GitHub and everybody can contribute to the project or download the ebook and start coding.
The new Eclipse MicroProfile Starter is live and it's really easy to generate a new project.
Go to https://start.microprofile.io/ and follow the steps below to generate a new project.
MicroProfile Rest Client is used to invoke RESTful services over HTTP and in this tutorial we will learn how to use it.
In this tutorial we will learn how to deploy our MicroProfile application on Heroku and we will use Payara Micro as our application server.
TomEE version 7.1.0 now supports MicroProfile and in this quick tutorial I will show you how to get started with MicroProfile Config using TomEE application server.
In this tutorial we will learn how to integrate tests with Arquillian using TomEE Application Server.
In this tutorial we will create a simple web application using MVC 1.0 (JSR 371), Thymeleaf, H2 database, JPA and Thorntail (Wildfly Swarm).
In this article we will learn how to use MicroProfile Metrics and Prometheus to collect metrics from monitored targets.
In this tutorial I will show you how to generate api documentation using MicroProfile OpenAPI and Payara Micro runtime.
Learn more about MicroProfile OpenAPI Specification
In this tutorial we will learn how to use MicroProfile Config API using Payara Micro
MicroProfile Config API can be used to retrieve configuration information from different sources.
In this tutorial we will learn how to create REST API using MicroProfile, MongoDB, Hibernate OGM and Thorntail (wildfly-swarm)
In this tutorial we will learn how to create a simple CRUD REST API with Java EE using H2 database and TomEE application server.
H2 is an open source relational database management system written in Java. It can be embedded in Java applications or run in the client-server mode and it is easy to install and deploy.
In this tutorial I'll show you how to get started with MicroProfile.
In this tutorial we are going to learn how to document our Spring Boot REST APIs using Swagger with Springfox.
In this tutorial, we are going to create a simple Spring Boot web application with Thymeleaf template engine and H2 database.
H2 is an open source relational database management system written in Java.
It can be embedded in Java applications or run in the client-server mode and it is easy to install and deploy.
With this tutorial I’ll show you how you can get started with Spring Boot.
