This class contains only static components and has been designed to run on Unix machines (even if porting to Windows architecure will be pretty easy it is enough to change the execution string "/bin/sh -c" whith the appropriate command.)
This class is basically based on the method Runtime.exec();

Method Detail

public static void main(java.lang.String[] args)

Routine used to test the class.

exec

public static int exec(java.lang.String[] param)

Executes a command and returns the stdOut and stdErr as strings.

Parameters:

param - way chosen way to pass strings.
In Java is not easy to pass String by reference. I chose to use an array of pointer to strings, You have to fill the first string with the command and this routine will fill other 2 strings with stdOut and stdErr

0 - in: command String
1 - out: StdOutput of the executed command
2 - out: StdError of the executed command

Returns:

the exit code of the command.
