 The Java class Process is used together with class Runtime. As explained by Oracle: "The Runtime.exec methods create a native process and return an instance of a subclass of Process that can be used to control the process and obtain information about it. The class Process provides methods for performing input from the process, performing output to the process, waiting for the process to complete, checking the exit status of the process, and destroying (killing) the process."​ (from the [[http://​docs.oracle.com/​javase/​1.4.2/​docs/​api/​java/​lang/​Process.html|Javadocs of version 1.4.2]]). The Java class Process is used together with class Runtime.

-After much tinkering, we decided manage ​to get [[MoDeC]] to work by using the "​new"​ class ProcessBuilder because "As of 1.5, ProcessBuilder.start() is the preferred way to create a Process."​ (according to [[http://​docs.oracle.com/​javase/​7/​docs/​api/​java/​lang/​Process.html|Oracle]] in a version of the Javadocs subsequent to 1.5). We modified essentially the code as follows:+After much tinkering, we managed ​to get [[MoDeC]] to work by using the "​new"​ class ProcessBuilder because "As of 1.5, ProcessBuilder.start() is the preferred way to create a Process."​ (according to [[http://​docs.oracle.com/​javase/​7/​docs/​api/​java/​lang/​Process.html|Oracle]] in a version of the Javadocs subsequent to 1.5).
