Java Code

Aight twn, here you’ll find some example code.

Closing Sessions.

package titanium;
 
public class Principal {
 
    private static void escribirMenu() {
		//Code for escribirMenu()...        
		System.out.println("0) - End program.");
		System.out.println("1) - <Action>.");
		System.out.println("2) - <Action>.");
		System.out.println("3) - <Action>.");	
    }
      public static void main(String[] args) {
        int opcion;
         do {
            escribirMenu();
            opcion = Teclado.leerEntero("Opcion: ");
 
            switch (opcion) {
                case 0:
                    System.out.println("Cya1!");
                   ------------------------------------------
                   | ObjectDBUtil.cerrarFabricaConexiones();| <- //Here close connections  
                   ------------------------------------------
                    break;
                case 1:
                //case 1 code...
                    break;
                case 2:
                //case 2 code...
                    break;
                case 3:
                //case 3 code...
                    break;
            }
        } while (opcion != 0);
    }
}

As you can see, in case 0: is when the program ends, and there is where we need to add the command to close all sessions, if not, sessions will stay awake and consuming resources and maybe, crashing the whole program.
