How To Run Java Program In Windows 10

Coffee is one of the most commonly used programming languages. It is too an IDE-intensive programming language, with tight integration with Eclipse. You can run Java programs from the Command Prompt for quick compiling and execution.

If y'all are just starting to learn Java, hither is a basic guide to help you starting time running the Java application from the Command Prompt in Windows.

Installing the Java Development Kit (JDK)

Before yous can run a Java program on your figurer, you'll need a dedicated compiler installed. This comes within the Coffee Evolution Kit (JDK). It's an essential tool for developing in Java on any platform.

The JDK is not the same as the Coffee Runtime Surroundings (JRE), which you lot'll already have installed if you've ever used a Java application on your automobile.

First, download the JDK from Oracle's website – the Windows version. Make sure non to download the "JRE to Server" editions.

Next, run the installer every bit you would for any other program and follow the instructions.

Running a Coffee Program from the Command Prompt

Create a simple Java program like the one below using Notepad or some other text editor. Make sure to salve the file with the extension ".coffee" rather than ".txt."

            public            class            HelloWorld            {            public            static            void            main(            String            [            ]            args)            {            Organization.out.println            (            "Hello, World!"            )            ;            }            }

Next, open the Command Prompt from the Windows Beginning Menu.

Use the cd control to alter your working directory to the directory containing your Coffee program.

            cd            Documents[Coffee-program-folder]

From here, locate the path to the version of the Coffee Evolution Kit (JDK) on your computer. For example, if you're running 64-bit Windows, that volition often be in "C:Program FilesJava."

Next, ready the path to the JDK with the set command:

            set            path=%path%;C:Programme FilesJavajdk-16.0.1bin

You may need to change the directory path to reflect the current version of Java. Make sure you're using the Java Development Kit (JDK) directory and pointing to the "bin" folder.

The Java Runtime Environment (JRE) folder also contains a "bin" folder but doesn't hold the Coffee compiler. If yous get errors around the compilation, make sure you're using the correct directory path.

Compile the Coffee plan with the javac control, as seen below:

Be warned that you'll see nothing happen. Though, if yous use the dir command, you'll notice a new file in your directory ending in the ".class" extension. This indicates the program has been compiled.

Finally, use the java command to run your program:

You'll run across the program run inside the Command Prompt window, merely at that place'southward one more task you can do to brand sure your Coffee program runs smooth – settings your path.

4. Select the Path variable, and so click the Edit button.

5. Click New to add together a new directory to your path.

6. Paste the directory path you used higher up into the text box. Once again, make sure you're using the Java Development Kit (JDK) directory and not the Coffee Runtime Environment (JRE) directory next to it.

Lastly, click OK to commit to the modify.
