For this simple option parsing example, you can populate a file called Main.java with the standard minimal code: package import. java files, say C:introcshello, by typing the cd command below. To use the commons-cli library in your code, you must import it. With the command and the required arguments and then pass it to ProcessBuilder instance as command. From the Command Prompt, navigate to the directory containing your. If you have to run the same command as used above using ProcessBuilder, which is a much clearer way to do that, you can create a list The command-line arguments in Java allow us to pass.

Using the getInputStream() method of Process class output of the executed command can be printed by reading the stream. /c- Executes the given command and terminatesĮxecution of the command returns instance of class Process.public Process exec(String command) throws IOException - Executes the specified string command in a separate process.Ĭmd /c which is used with the command has the following explanantion.public static Runtime getRuntime() - Returns the runtime object associated with the current Java application.
The method must be declared public and static, it must not return any value, and it must accept a String array as a parameter.
It does this by starting the Java Virtual Machine (JVM), loading the specified class, and calling that classs main () method. Runtime.getRuntime().exec method is used to run the command. The java command starts a Java application. Here it can be seen that directory listing is displayed for the directory which happens to be the workspace directory
