jcombobox holding array of int error

Question

Can a Jcombobox hold an int? because i tried this and got an error.

int[] timeSched = new int[] {200,300,400,500}; JComboBox Jcombo1 = new JComboBox(timeSched);

Answer 1

int[] is not the same as Object[].

Instead of int[] you can use Integer[] which is a wrapper class for the primitive int type, something like...

Integer[] timeSched = new Integer[] {200,300,400,500};

This allows the value to be passed to the JComboBox's constructor which is expecting a generic array of Objects.

Remember, generics in Java don't support primitives as there base class it defined off Object and primitives are a special (non-object) type in Java
