I have created Students individuals in Jena and stored them in a file. Every time students login, updates their information like GPA and updates stored in the file. Student.createIndividual(ns, stdName);
With this statement, suppose a student Neha is created with her information in the file. Next time, she login, again a new instance will be created when the application executes *Student.createIndividual(ns, stdName);?* *Is there any condition which states if the individual not already exists, create it otherwise skip createIndividual statement?*
