我想从.txt填充JList
我无法填充JList ...
这是代码:
.txt的格式类似于以下示例:
name1
name2
name3
JList以这种方式声明:
private javax.swing.JList jList1
这是用于逐行读取的方法:
private void visualizzaRosa(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
fileSquadra = squadra.getText();
try {
FileInputStream fstream = new FileInputStream("C:/Users/Franky/Documents....");
DataInputStream in = new DataInputStream(fstream);
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String strLine;
while ((strLine = br.readLine()) != null) {
Jlist1.add(strline); //to populate jlist
System.out.println(strLine); //to print on consolle
}
in.close();
} catch (Exception e) {
}
}
谢谢
最佳答案
尝试
DefaultListModel listModel = new DefaultListModel();
while ((strLine = br.readLine()) != null)
{
listModel.addElement(strline);
System.out.println(strLine);
}
jList1.setModel(listModel);
