Java Platform, Micro Edition (Java ME) provides a robust, flexible environment for applications running on embedded and mobile devices in the Internet of Things: micro-controllers, sensors, gateways, mobile phones, personal digital assistants (PDAs), TV set-top boxes, printers and more. Java ME includes flexible user interfaces, robust security, built-in network protocols, and support for networked and offline applications that can be downloaded dynamically. Applications based on Java ME are portable across many devices, yet leverage each device's native capabilities.
Java Platform, Micro Edition or Java ME is a computing platform for development and deployment of portable code for embedded and mobile devices (micro-controllers, sensors, gateways, mobile phones, personal digital assistants, TV set-top boxes, printers).[1] Java ME was formerly known as Java 2 Platform, Micro Edition or J2ME. As of December 22, 2006, the Java ME source code is licensed under the GNU General Public License, and is released under the project name phoneME.
The java agent and properties file configuration can be added to environment variables depending on the application server the application is running with, in order to be set on the jvm command line. Refer to the list below.
I had micro focus support jump in and have a look, and I had a few of their guys remotely controlling my server for well over an hour in a webex session and they coulcn't work it out so ended up raising a ticket.
You seem to be asking for this entire span of time as a count of milliseconds. Be aware this means data-loss as any microseconds or nanoseconds in the fraction of a second are truncated to milliseconds.
The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.
I saw on the Internet that I was supposed to use System.nanoTime() but that doesn't work for me - it gives me the time with milliseconds precision. I just need the microseconds before and after my function executes so that I know how long it takes. I'm using Windows XP.
Basically, I have this code that, for example, does 1 million up to 10 millions of insertions in a java linked list. The problem is that I can't measure the precision right; sometimes it takes less time to insert everything in the smaller list.
To be clear, the microseconds resolution asked in the Question is in between the granularities of milliseconds and nanoseconds. Number of places in a decimal fraction: millis is 3 (0.123), micros is 6 (0.123456), nanos is 9 (0.123456789).

Microservices have been quite popular in the Java ecosystem ever since Spring Boot and Spring Cloud made them easy to build and deploy. Things have gotten even easier in recent years with the proliferation of new Java frameworks built specifically for microservices: MicroProfile, Micronaut, Quarkus, and Helidon. Not only do these frameworks provide an excellent developer experience, but they also tend to have built-in Docker support. They even work with GraalVM, so you can compile your apps to native code!
Today, I'll show you how to build a Java microservices architecture that leverages micro frontends for the UI. The backend will use Spring Boot and Spring Cloud, while the frontend will use React. You can also use Angular or Vue if you'd like.
JHipster is an application generator that creates a Spring Boot backend. You can configure it to use SQL or NoSQL databases, plain ol' Spring MVC, or reactive with WebFlux. It also generates a UI for your REST API and offers you the choice of Angular, React, or Vue. Last year, I showed you how to build reactive Java microservices with Spring Boot and JHipster. In this tutorial, you'll build a gateway with Spring Cloud Gateway. Then, you create a blog microservice and a store microservice, each with its own database.
This microservices architecture had one major flaw: the UI for it is a monolith, with all its files on the gateway. This isn't good from a loose-coupling point of view because changes in a microservice might require changes in the UI. Instead of being able to deploy the microservice independently, you have to deploy the gateway too.
Today, I'm proud to show you how you can solve this problem with micro frontends. JHipster recently added support for micro-frontends. Microfrontends provide a way for you to remotely load and execute code at runtime so your microservice's UI can live in the same artifact without being coupled to the gateway!
Webpack's Module Federation is one of the best-known implementations for micro frontends. Its ModuleFederationPlugin allows a build to provide or consume modules with other independent builds at runtime. It even allows you to share libraries between frontends to reduce the size of remote bundles.
Zack Jackson is the creator of Module Federation and recently collaborated with Manfred Steyer to create Native Federation. This means you can use micro frontend concepts with any build tool, not just webpack.
I think micro frontends are a fascinating architectural concept. Microservices weave everything together on the backend with protocols like HTTP and gRPC. With micro frontends, it's all HTTP. You can see your app get stitched together by watching your browser's network console and seeing remote modules-load.
I've encountered quite a few monolith UIs in my time as a consultant. The backend was beautiful microservice architecture, but it was all tightly coupled on the frontend. There's a good chance many Java developers don't care about the UI because they just work on the beautiful backends. However, if you consider yourself a Java web developer, micro frontends are as revolutionary as HTML5!
The last two arguments are optional, but I expect you to use them for this tutorial. Without the monorepository flag, the gateway and microservices would have their own Git repos. The workspaces flag enables npm workspaces, which is kinda like having an aggregator pom.xml that allows you to execute commands across projects. It also makes it, so there's only one node_modules in the root directory. To learn more, I recommend egghead's Introduction to Monorepos with NPM Workspaces.
The gateway's webpack.microfrontend.js handles specifying the shared dependencies and components between apps. The src/main/webapp/app/shared/layout/menus/entities.tsx file contains the menu items for each micro frontend.
Now, Spring Security will be configured to use Auth0, and Consul will distribute these settings to all your microservices. When everything is started, navigate to :8080 and click sign in. You will be prompted for your Auth0 credentials.
I won't go into the nitty-gritty details of deploying a JHipster microservices stack to cloud providers with K8s, mainly because it's covered in previous blog posts. The first post below shows how to run Minikube locally, encrypt your secrets, and deploy to Google Cloud.
I hope you enjoyed this overview of how to use micro frontends within a Java microservices architecture. I like how micro frontends allow each microservice application to be self-contained and deployable, independent of the other microservices. It's also pretty neat how JHipster generates Docker and Kubernetes configuration for you. Cloud-native FTW!
View the Milky Way at 10 million light years from the Earth. Then move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. After that, begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, chromatin, DNA and finally, into the subatomic universe of electrons and protons.
Scientists examine things in particular ways using a combination of very sophisticated equipment, everyday instruments, and many unlikely tools. Some phenomena that scientists want to observe are so tiny that they need a magnifying glass, or even a microscope. Other things are so far away that a powerful telescope must be used in order to see them. It is important to understand and be able to compare the size of things we are studying. To learn more about the relative sizes of things, visit our Perspectives: Powers of 10 activity site.

I can't get the Supermicro IPMIView version 2.* (any of them) to launch the KVM Console either in the IPMIView windows program nor any browser. Java, is installed (version 8, update 131) and I'm running Windows 8.1 (though IPMIView 2 won't run on my Windows 7 laptop, nor any of the Windows 10 machines). All 3 machines have the same problem: The KVM Console simply will not run on any of them. I can connect to the Supermicro server, turn it off/on/reboot, read all of the sensors just fine. The ONLY thing not working is the KVM Console.
Helidon was the first microservice framework that supports EclipseStore. Both Helidon flavours, Helidon MP and SE provide a great EclipseStore integration. Helidon is a leading microservice framework for Java, powered by Oracle.
