怎样得到Jlist或者说DefaultListModel已选择的项？

我在两个JList中分别添加了两个DefaultListModel，里面的选项是String类型的，怎样才能得到选择项的值？

Answer 1

通过JList，有单选或多选的两个情况

int getSelectedIndex()

a single item is selected in the list.
int[] getSelectedIndices()
Returns an array of all of the selected indices, in increasing
order.
Object getSelectedValue()
Returns the value for the smallest selected cell index;
the selected value when only a single item is selected in the
list.
Object[] getSelectedValues()
Returns an array of all the selected values, in increasing order based on their indices in the list.
