Question

拼写错误，大小写错误，见下在面的改正：
import java.util.*;import javax.swing.*;public class LotteryDrawing

    public static void main(String[] args)  //pubilic
   
    {
      String input=JOptionPane.showInputDialog

                     n--;
                     }
                     
                     Arrays.sort(result);
                     
                     System.out.println  //system
