How can I get the text from a component in a JList?
提问by soldier.moth
I have a JListand I am wanting to get the text of an entry of that list at a specific index. Could someone inform me how to do this or should I restructure my code to getValuesinstead of getIndices?
我有一个JList,我想在特定索引处获取该列表条目的文本。有人可以告诉我如何做到这一点,或者我应该将我的代码重构为getValues而不是getIndices?

JList dataList=(...)
for(int i = 0; i < dataList.getModel().getSize(); i++) {
System.out.println(dataList.getModel().getElementAt(i));
}

Object[] temp = jList1.getSelectedValues();
temp[i] = the object you want.

DefaultListModel list = new DefaultListModel();
JList jl = new JList(list);
int i = 21;
Object = element;
String = yourElement;
element = jl.getModel().getElementAt(i);
yourElement = element.toString;
