private void originComboBox() {

        scheControl = new ScheduleControl();
        Schedule schedule = scheControl.getRecord();
        String origin = schedule.getDeparture();

        for(int i = 0; i < origin.length(); i++){
            originCB.addItem(origin);
        }       
    }

Answer 1

You are adding the same origin each time. Shouln't it be origin[i] ?

for(int i = 0; i < origin.length(); i++){
    originCB.addItem(origin[i]);
} 

Answer 2

String origin = schedule.getDeparture();

• Your getting single string only.
• you have to get array of values. Do
• the modification than you will get result as you need. you can use
• for-each loop to check the values of array.

Answer 3

you could try this

 for(int i = 0; i < origin.length(); i++){
    originCB.addItem(origin[i]);
} 

where origin should be Array .

    String origin[]={"A","B","C"};
