你最好使用具有内置选择功能的JList或JTable。这里是JTable的Oracle文档基础部分。
我建议在初学时使用JTable与DefaultTableModel。
英文:
You would be better off using a JList or JTable which have built in selection functionality. Here is the Oracle documentation on the basics of JTable.
I suggest using JTable with the DefaultTableModel when you are first getting started.

你可以使用一个名为 process 的方法来打开文件或执行操作。
using System.Diagnostics;
Process p = new Process();
ProcessStartInfo pi = new ProcessStartInfo();
pi.UseShellExecute = true;
pi.FileName = @"MY_FILE_WITH_FULL_PATH.jpg"; //c:\Desktop\example\sample.txt
p.StartInfo = pi;
try
{
p.Start();
}
catch (Exception Ex)
{
//MessageBox.Show(Ex.Message);
}
英文:
Well you can open a file or execute using a method called process
using System.Diagnostics;
Process p = new Process();
ProcessStartInfo pi = new ProcessStartInfo();
pi.UseShellExecute = true;
pi.FileName = @"MY_FILE_WITH_FULL_PATH.jpg";//c:\Desktop\example\sample.txt
p.StartInfo = pi;
try
{
p.Start();
}
catch (Exception Ex)
{
//MessageBox.Show(Ex.Message);
}
