Question

JAVA中getSelectedIndex()是什么作用

list中有l.getSelectedIndex()是什么作用
知道的亲，请告诉我
谢谢了，我急着知道

Answer 1

得到链表中所选项目的索引
没有一个项目被选中就返回-1
jdk文档里如下说：
public int getSelectedIndex()
Gets the index of the selected item on the list,

Returns:
the index of the selected item; if no item is selected, or if multiple items are selected, -1 is returned.
See Also:
select(int), deselect(int), isIndexSelected(int)

Answer 2

int getSelectedIndex()
Gets the index of the selected item on the list, //得到选中条目的号呀
没事多看看API 很好
