问题描述
我想通过for循环将Objects
的Arraylist
中的项目中的toStrings
添加到Jlist
中.我尝试过了.
I want to add the toStrings
from items in an Arraylist
of Objects
to a Jlist
through a for loop. I tried this.
for (int i = 0; i < customer.slist.size(); i++) {
((DefaultListModel) checkOutList.getModel()).addElement(customer.slist.toString());//slist is an array of objects.
}
但是它没有用.另外,当我尝试
But it didnt work. Also NetBeans tells me .addElement()
is not a method for a JList
when I tried
checkOutList.addElement("anything")
推荐答案
而不是
customer.slist.toString()
customer.slist.toString()
尝试:
customer.slist.get(i).toString();
customer.slist.get(i).toString();
在您的代码中.
