JComboBox to string
提问by gabrielle fregil
I have a String array of names, and then I added it into an editable JComboBox.
我有一个字符串名称数组，然后我将它添加到一个可编辑的 JComboBox 中。
The user can either pick his/her name from the choices or just input his/her name if not in the choices.
用户可以从选项中选择他/她的名字，或者如果不在选项中，则只输入他/她的名字。
How do I put the user input into a new string variable?
如何将用户输入放入新的字符串变量中？
String [] chooseName = { Mark, John, Allison, Jessica };
JComboBox combo = new JComboBox (chooseName);
combo.setEditable(true);
String chosenName = /* how do i place what the user inputed here? */

I would add an action listener to the combo box. By doing it in the same block there, it will simply grab the default (I believe). This way we make sure we grab the value once selected.
我会向组合框添加一个动作侦听器。通过在同一个块中执行它，它会简单地获取默认值（我相信）。这样我们就可以确保我们在选择后获取值。
String [] chooseName = { Mark, John, Allison, Jessica };
final JComboBox combo = new JComboBox (chooseName);
combo.setEditable(true);
combo.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
String chosenName = (String) combo.getSelectedItem();
}
});
