The Java toolset that comes with the JDK supports the execution and management of running Java applications as well. To have some program that we can manage while executing, we will need a code that runs not only for a few milliseconds but, while it runs, it also prints something to the console. Let's create a new program called HelloWorldLoop.java, with the following content:
