How can I store inputs given by the user from GUI to a string array in java? I am using java swing to create the GUI

Question

i have created a drop down menu and i want to store which option the user is choosing from the menu to an array of strings so that i can use the string array later. How can I do it?

Answer 1

您可以使用ArrayList并使用方法getSelectedItem（）存储选择。

Answer 2

Whenever possible try to use Collection framework in java, it gives more flexibility.

Example:

ArrayList<String> arr = new ArrayList<String>();
JComboBox jb = new JComboBox();
jb.add("Vivek");
jb.add("Vishal");



jb.addActionListener(new ActionListener() {

    @Override
    public void actionPerformed(ActionEvent arg0) {

        arr.add(jb.getSelectedItem().toString());
    }
});
