Use shell variables in the script, set them in Java through the environment:

import java.util.Map;

class so1 {

    public static void main(String[] args) {

        try {
            ProcessBuilder pb = new ProcessBuilder("/home/...sh");
            Map env = pb.environment();
            env.put("VAR1", "something");
            Process p = pb.start();    
            p.waitFor();              
            System.out.println("Script executed successfully");
        } catch (Exception e) {
            e.printStackTrace();
        }

    }

}

In the script:

/usr/local/virtuoso-opensource/bin/isql 1111 dba dba exec="SPARQL CREATE GRAPH $VAR1;"&
