Method getRunTime is used to get the reference of the current RunTime object. The exec method can be used to execute commands. You can also specify a file while opening Notepad, such as exec("notepad programming.txt"), where 'programming.txt' is the file you wish to open. If the file doesn't exist in the current working directory, then a dialog box is displayed to create a file.

You can launch other applications using the exec method. For example, exec("calc") launches the calculator application. If an application is present in a directory that isn't set in environment variable PATH, then you can specify the complete path of the application.

If you are still using Notepad for Java development, it's recommended to switch to some advanced text editor like Notepad++ or use a development IDE.
