ComboBox takes in String values. How can I use a loop to insert 1-10 (1 to 10) in a ComboBox?

Question

Just want to insert 1-10 values in a ComboBox. How to convert int i to string values?

    for(int i=1;i<11;i++){

        quantityCombo.addItem(i); //Not accepting int values
    }

Answer 1

 Use Generics and Try Like this....
     JComboBox<Integer>  quantityCombo= new JComboBox<Integer>();

        // add items to the combo box
         for(int i=1;i<11;i++){

                quantityCombo.addItem(i);
            }

Answer 2

You can use Integer.toString(i) to convert your integer into a String. Your code will look like this:

for(int i=1;i<11;i++){
    quantityCombo.addItem(Integer.toString(i));
}

Answer 3

When in doubt, read javadoc.

You are looking for Integer.parseInt(int), or toString(int). Plenty of choices.

And the real way of solving this is to give a model to the combo box. You don't want to add its "items" one by one; you create a data structure (for example an array) that you pass as one thing; see the official tutorial.

Finally: ComboBoxes accept a type parameter; so as khaja suggested, you can also create a ComboBox that will display only Integer entries. And when an Integer is expected, the compiler will do the work for your, and

quantityCombo.addItem(i);

works out of the box - because the compiler does auto-boxing to create an Integer object from the provided int value.
