I have created a java form with NetBeans, a JFrame (Main), Dialog (Enrollment), Student Class, Student Manager Class. In Enrollment I have 2 comboboxes one for the cycle and another for the course, depending on that the txtcredito (Credito) and txtcostocredito (CostCredit) is filled according to the table:
This is the form:
I have done the programming for the calculate button (credit * costcredito) = montomatricula. and the summary button that shows you all the entered data (Name, Surname, Cycle, etc.).
Also perform the conditional with the combobox to fill the textbox but do not show it to me. There I require your support. I put the code to help me.
FrmCalculaMatricula (JDialog)
