What is JCompiler?

This class considerably helps you to compile at the run time. For using it, you should inherit from the JCompiler class, then use the “addFileToWindowsRuntime”, create a new class. Afterward you can create an object from the created class by using JShooter.

Code:

********************
package mypackage;
import org.j2sos.shine.jshooter.Application;
import org.j2sos.shine.maplet.Maplet;
public class Engine extends Maplet {
   public String name;
   public String body;
   public void learning() {
       try {
           new Memory().addMethod("public String " + name +
               "() throws Exception {" + body + "}");
           out.println("Learned.");
       } catch (Exception e) {
           out.println(e.getMessage());
       }
   }
   public void request() {
       try {
           Application app = new Application();
           app.setObject(new Logic());
           out.println(app.invokeMethod(name));
       } catch (Exception e) {
           out.println(e);
       }
   }
}
