Java Para Windows 11 64 Bits

[Katrine Freggiaro]

Entrelas ventajas que ofrece el lenguaje de programacin Java se encuentra la funcionalidad multiplataforma, la seguridad y algunas funciones prcticas como el multithreading, presente incluso en el nuevo Windows 11. Sin embargo, antes de instalar Java en Windows 11, deberas comprobar si necesitas la versin Java de 32 bits o de 64 bits.

Java es uno de los lenguajes de programacin de internet ms extendidos y populares, y resulta incluso interesante para usuarios que estn aprendiendo a programar. Al igual que en el actual Windows 11, tambin puedes instalar Java en Windows 10. En ambos casos, basta con descargar una copia gratuita desde el desarrollador de Java, Oracle Corporation.

Atencin: Desgraciadamente, los plug-ins de Java no son compatibles con el navegador Edge, por lo que no se puede utilizar Java en este navegador marca Windows. Sin embargo, hay otros navegadores en los que s se puede usar Java con su correspondiente plug-in o applet, como es el caso de Firefox y Safari. Asimismo, deberas tener claro si necesitas la versin de Java para Windows de 32 bits o de 64 bits.

Usa Java de la manera ms eficiente aprendiendo los comandos de Java y operadores de Java ms prcticos. El Software Development Kit, abreviado SDK, proporciona un prctico kit de Java. El JDK (Java Development Kit) incluye varias herramientas, servicios y el entorno de ejecucin de Java.

Java ha dejado de ser compatible con los sistemas de 32 bits, por lo que Java actualmente solo funciona en sistemas operativos de 64 bits. Sin embargo, en los sistemas operativos de 64 bits funciona sin problemas tanto la versin de 32 bits como la de 64 bits. Si utilizas tanto un navegador de 32 como de 64 bits, ambas versiones de Java son igual de recomendables. Oracle Corporation, por su parte, aconseja utilizar un navegador estndar de 32 bits y la versin de Java de 32 bits para obtener el mejor rendimiento.

Paso 1: Abre la pgina de descarga de Java de Oracle Corporation java.com en tu navegador habitual. En la pgina podrs ver una lista de las versiones actuales de Java para Windows, Linux, macOS e incluso Solaris.

Si no solo quieres utilizar Java en el navegador, sino tambin como lenguaje de programacin, puedes descargar el Java Development Kit (JDK) de la pgina web de Java. El JDK cuenta con herramientas y programas tiles como el editor de Java, un compilador e intrprete, un debugger, herramientas de catalogacin, clases API, archivadores, programas para firmar, herramientas para applets y monitorizacin del rendimiento as como un importador de servicios web. El entorno de ejecucin de Java (JRE) tambin viene incluido en el JDK.

Paso 1: Abre la pgina web de Java para desarrolladores. En la pgina principal vers el botn de descarga de la versin actual de Java (a fecha de 2022: Java 18). Si quieres usar el Java Development Kit, dirgete a la pgina web de Oracle para descargas de Java y descarga el archivo de instalacin correspondiente.

Paso 3: Dependiendo de la opcin de descarga elegida, extrae los archivos ZIP descargados o haz doble clic en el archivo ejecutable. El asistente de instalacin de Java te guiar paso a paso por la instalacin. En solo unos minutos ms tarde tendrs Java a tu disposicin.

This page provides basic JOSM installation steps and troubleshooting information.To start working with JOSM please see the Introduction and the Help pages. And for very complex issues see Installation Notes.

Every month the team of JOSM releases a tested version for download. The MS Windows and Apple macOS variants are built on this tested version.When you click on josm.jnlp to launch JOSM you will always get the newest tested version. Java's Web Start is the mechanism behind this.

Every night the build systems generate a latest version.These versions might have severe errors. But mostly they work well, too.For the latest version is also a Web Start variant available.

Strip translations

If download size is an issue, smaller files of the tested version are available. For downloads containing only English append ?lang=en to the URL. To include one translation replace en with the language code you want (lowercase first character, supported languages only). You can further reduce the file size by stripping the signing information off with appending ?unsigned=1.

This is our own package repository primarily for Ubuntu. It should also work with other Debian based (especially Ubuntu based) distributions, but we do not actively test and maintain any distributions other than Ubuntu.

On current versions of MS Windows by default Java is installed mainly in the C:\Program Files\Java\ directory. Additional parts are placed in C:\Program Files\Oracle\Java\. There is a .\javapath\ directory as target for the PATH environment variable. It is the home for the three virtual files java.exe, javaw.exe and javaws.exe. This files are symbolic links form the current Java installations.

On older versions of 64 bit Windows sometimes the 32 bit mode JRE was additionally installed. Also some browsers brought their own JVM with limited capabilities. In those cases a Web Start from the browser would not use your Java installation but that from the browser.

Check that there's no other javawebstart in \Windows\SysWow64. The Java control panel will not detect it and you can safely delete it. Perform cleanup and only keep the latest versions of each JRE (One or the 32-bit mode, another one for the 64-bit mode).

For shortcuts created on the desktop for JNLP and running the Javawebstart launcher , make sure to pass VM parameters prefixed with -J and no intermediate space before the VM option. If you have installed both the 32-bit and 64-bit version, you should pass the option "-d64" if you want to select the preferred 64-bit VM. Note that some Oracle documentation pages indicate the option "-D64" with the incorrect capitalization!)

jSerialComm is a Java library designed to provide a platform-independent way to access standard serial ports without requiring external libraries, native code, or any other tools. It is meant as an alternative to RxTx and the (deprecated) Java Communications API, with increased ease-of-use, an enhanced support for timeouts, and the ability to open multiple ports simultaneously.

One of the most convenient features of this library is that it allows you to simply include the JAR file in your custom project, and it will automatically select and load the correct native library for your platform and architecture. As such, you can make use of this library by simply copying the jSerialComm.jar file into your project directory and linking to it as you would any other JAR file.

To access the contents of the library in your project, make sure to import com.fazecast.jSerialComm.* into your java files. You can then generate a list of all available serial ports on your system (real or virtual), by calling the following static method:

This will return an array of SerialPort objects through which you can iterate. See the Javadoc Library Reference for a complete overview of this library and its methods. Alternately, if you already know the port descriptor of the port you wish to use (e.g., "/dev/ttyS0" or "COM3"), or if you are using this library with pseudo-terminals (e.g., "/dev/pts/14"), you can create a SerialPort object using the following static method:

Note for Linux users: Serial port access is limited to certain users and groups in Linux. To enable user access, you must open a terminal and enter the following commands before jSerialComm will be able to access the ports on your system. Don't worry if some of the commands fail. All of these groups may not exist on every Linux distro. (Note, this process must only be done once for each user):

Replace the username parameter with your current username. (If you are not sure what your username is, type whoami and it will tell you.) If you are using SUSE 11.3 or higher, replace the '-a -G' flags with a single '-A' flag. Log out and you should have access to the serial port after logging back in.

Additionally, if you are using an automated build system (such as Maven), you can import this library directly into your project as a dependency from the Maven Central Repository instead of copying the .jar file manually. Use one of the following dependency declarations depending on the build system you are using:

Although this library was designed to be as simple and flexible as possible, you can enable a number of different modes of operation via manipulation of the serial port timeout values and the interface through which you choose to access the serial port.

For a description of the various modes of operation available in this library, please refer to the Modes of Operation wiki article. For code-based examples of how to use this library in your own project, we provide a Usage Examples wiki.

To install OpenCV (with Java support) through Homebrew, you need to edit the opencv formula in Homebrew, to add support for Java:brew edit opencvIn the text editor that will open, change the line:-DBUILD_opencv_java=OFFin-DBUILD_opencv_java=ONthen, after saving the file, you can effectively install OpenCV:brew install --build-from-source opencv

Please, note: the following instructions are also useful if you want to compile OpenCV under Windows or macOS. Linux package management systems (apt-get, yum, etc.) may provide the needed version of the OpenCV library.

Now open the terminal, go to the build folder of OpenCV and compile everything with the command: make -j. Notice that the -j flag tells make to run in parallel with the maximum number of allowed job threads, which makes the build theoretically faster.Wait for the process to be completed...If everything went well you should have opencv-3xx.jar in the /opencv/build/bin directory and libopencv_java3xx.so in the /opencv/build/lib directory. The 3xx suffix of each file is a shortcut for the current OpenCV version, e.g., it will be 300 for OpenCV 3.0 and 330 for OpenCV 3.3. This is everything you need.
