实在是无聊到爆 public class Wuliao {

  public static void main(String[] args)
  {
  
  int x=3;
  
  while (x>0)
  {
  if (x>0)
  {
  System.out.print("a");
  }
  
  if (x==2)
  {
  System.out.print("b c");
  }
  
  if (x==1)
  {
  System.out.print("d");
   x=x-1;

  }
  x=x-1;
  System.out.print("-");

  }

} }

运行结果是 a-b c-d
