How can I use Sublime Text 3 to launch a Java program?
Java is one of the most preferred programming languages used to develop software of all kinds. In case you need an easy and fast way to type and run your Java programs, Sublime Text 3 is the appropriate choice. It is one of the lightest weight text editors around, which can be configured to compile Java code. Let me show you how.
Why Use Sublime Text 3 for Java?
Sublime Text 3 is a lightweight, basic text editor. Many developers just love it because it is straightforward and can be extended easily. Although this is not an IDE in the full sense, which was expected if Eclipse or IntelliJ IDEA were chosen, it can be useful too for maintaining and running Java programs if you want something less bulky.
Step 1: Install the Java Development Kit (JDK)
Before you can run Java programs, you'll need to download and install the JDK. The JDK is a package containing everything you'll need to compile and run Java programs.
Download the JDK: You will have to go on an Oracle JDK website or should be using OpenJDK in order to download it.
Install JDK: You can follow through with the operating system you use, be it Windows, macOS, or even Linux.
Configure the Path: Add the JDK bin directory to your system's PATH. This allows you to run the Java commands from any directory using your terminal.
Step 2: Install Sublime Text 3
If you haven't downloaded Sublime Text 3 yet, here's how you get it:
Download Sublime Text 3: go to the Sublime Text website, downloading the version for operating system.
Install Sublime Text 3: Do an Installation process by following the installation instructions.
Step 3: Set Up Java in Sublime Text 3
To run Java programs in Sublime Text 3, you need to set it up properly:
Install Package Control:
Open Sublime Text 3.
Press `Ctrl+`` to open the console.
Paste the following code and press Enter: Copy the code: import urllib.request,os,hashlib; h = 'c7c3170dba8a36b8d3e4fb64cdbc5a1725dbbcfd93675e0b4ec9c1b58f01a4c6'; pf = 'Package Control.sublime-package'; ipp = sublime.installed_packages_path(); urllib.request.install_opener(urllib.request.build_opener(urllib.request.ProxyHandler())); by = urllib.request.urlopen('https://packagecontrol.io/' + pf.replace(' ', '%20')).read(); dh = hashlib.sha256(by).hexdigest(); print('Error validating download (got %s instead of %s), please try manual install' % (dh, h) if dh != h else open(os.path.join(ipp, pf), 'wb').write(by))
This installs Package Control, which helps you add other useful packages.
2. Install the Java Package:
Press Ctrl+Shift+P to open the Command Palette.
Press Enter after typing Package Control: Install Package.
Search for Java and install it. This package will add syntax highlighting and basic build system support for Java.
3. Set Up a Build System:
Go to Tools > Build System > New Build System.
Replace the default content with the following:
Save the file as Java.sublime-build.
Step 4: Write and Run a Java Program
Now that you've set up Java in Sublime Text 3, you can write and run your Java programs.
Create a New Java File:
Open Sublime Text 3 and go to File > New File.
Write your Java code. For example:
Save the file with a .java extension (e.g., HelloWorld.java).
Compile and Run the Program:
Press Ctrl+B to build and run the program.
The output will appear in the Sublime Text console at the bottom of the window.
Step 5: Troubleshooting Common Issues
If there is any kind of problem in running Java files in Sublime Text 3, then here are a few troubleshooting tips:
Path: The PATH environmental variable should contain the JDK bin directory.
Error Checking Follows: Sublime Text 3 is capable of detecting syntax errors, but you have to make sure and check for the common Java errors in your code as well.
Naming Conventions: The name of the java file should have the same name as that of the public class in your Java.
Conclusion
Using the right plugins and the build systems for Java, Sublime Text 3 is going to be lightweight but powerful software. Whether you are a professional or a beginner in this language, setting up Java in Sublime Text 3 is much straightforward and will significantly increase the quality of your coding experience. Just follow this guide, and in no time you will be running Java programs in Sublime Text 3.
By optimizing your work process in Sublime Text 3, you will be able to spend more time crafting fantastic code and less time learning some super obtuse IDE. Happy coding!
