Could someone tell me how can I assign 2 column values to the JComboBox from mysql database. I want to hide one of the column and show only the other one. however, when retrieving the selected value from the combobox, I want to get the hidden value associated with the selected item."
有人能告诉我如何从mysql数据库中为JComboBox分配2个列值。我想要隐藏其中一个列并仅显示另一个列。但是，当从组合框中检索所选值时，我想获得与所选项目相关联的隐藏值。“

Store objects in your combo box:
将对象存储在组合框中：
public class TwoColumns {
private String hiddenValue;
private String displayedValue;
// constructors, getters
@Override
public String toString() {
return displayedValue;
}
}
This is just an example: you should choose more meaninful names for the class and the fields.
这只是一个例子：您应该为类和字段选择更多有意义的名称。
