Sublime Text is a very popular editor for writing code. For Java, it supports compiling a Java source file with the default build named JavaC. Click Tools > Build System > JavaC to set the default build type for Java:

Then you can compile the current Java source file by clicking Tools > Build or press the shortcut key Ctrl + B.

NOTE: To be able to compile and run Java source files in Sublime, the Java compiler (javac) and Java launcher (java) programs must found in the PATH system variable. See: How to set environment variables for Java using command line

If there’s a compilation error, Sublime captures and displays the Java compiler’s output right inside the editor like this:

The .class file is generated in the same folder as the source file.

In case the compilation is successful, Sublime simply displays the following message:

 

However, Sublime Text 3 doesn’t have build-in support for running a Java program. So to run a Java source file, we need to configure the build system a little bit.

Click Tools > Build System > New Build System… And in the untitled.sublime-build editor, type the code as follows:

Save this file as RunJava.sublime-build in the folder prompted by Sublime. Then you could see the new build appears in the menu like this:

 

Now, to run the current Java source file, set the default build as RunJava and press Ctrl + B. Sublime captures and displays the program’s output right inside the editor like this:

 

If you want to compile and run a Java program in just a single keystroke, modify the RunJava.sublime-build file as follows:

{
	"shell_cmd": "javac $file && java $file_base_name"
}

Save the file. Now, press Ctrl + B and you will see the magic happens: the current Java source file is compiled and then executed (if no compilation errors).

That’s how to compile and run a Java program with Sublime Text 3 in simple way. Happy coding!
