How to declare a Combobox without using a string in its declaration?
What i mean to ask is how can i declare a combobox first and initialise the values later?
For example
JComboBox x= new JComboBox(); ... String s={"Alpha","Beta","Gamma"}; ... setSomething.JComboBox(s);
Is it even possible? From all the examples and tutorials so far i haven't found any which tells me how to do this.
Help will be very much appreciated!
