How do I call docker container using java commandline?

Question

I'm trying to run docker container from inside a java application.

Code

String[] command = {"docker exec -it test_docker java -jar test.jar"};
ProcessBuilder pb = new ProcessBuilder(command);
pb.inheritIO();
Process proc = pb.start();

While running the code I am getting an error,

Exception in thread "main" java.io.IOException: Cannot run program "docker exec -it test_docker java -jar test.jar": CreateProcess error=2, The system cannot find the file specified
        at java.lang.ProcessBuilder.start(Unknown Source)
        at com.test.company.test.RunTask.main(RunTask.java:79)

        at java.lang.ProcessImpl.<init>(Unknown Source)
        at java.lang.ProcessImpl.start(Unknown Source)
        ... 2 more

Here is my container list,

$ docker ps
