.class file not being created in Sublime Text: Java

Question

I am starting to learn Java and decided to use sublime text. I prepared a build system that would allow me to both compile and run the program. When I created my first file, it gave an error:

Error: Could not find or load main class Helloworld
Caused by: java.lang.ClassNotFoundException: Helloworld

My code:

public class Helloworld
{
    public static void main(String[] args)
    {
        System.out.println("Helloworld")
    }
}

The name of this file is Helloworld.java. I noticed one thing that the directory in which I saved this file didn't have the main class file. I am confused. Please help.

Build system code:

{
    "shell_cmd": "java $file_base_name"
}

javac $file_base_name (note the c) will compile your source file; java com.foo.YourClass will run it - note that the java command does not take a filename; it takes a class name.

More generally once you introduce packages and dependencies these scripts become impossible. Instead, use a build system and then if you still insist on using SublimeText (the vast majority of java programmers use IDEs such as Eclipse or IntelliJ), you can put mvn compile or mvn run in your compile/run scripts.
