Is it possible to add a String to a JComboBox without using an array? I have an adding button that should add to combo box after clicking on it but I don't know how to do that.

Use DefaultComboBoxModel.addElement(E). More generally, see How to Use Combo Boxes.
使用DefaultComboBoxModel.addElement（E）。更一般地说，请参阅如何使用组合框。

Andrew is correct, you don't need to go to the model though. The jComboBox class provides an addItem method for you.
安德鲁是对的，你不需要去模特。 jComboBox类为您提供addItem方法。
